sorry about taking so long to get back to ya i was up north camping with very little internet,the carb is from N R RACING -Carburetor, Honda GX390, Bored (24 mm) / Custom Header built by SPS Long Tail ,what you can do is call N R racing and he will tell ya just what ya need ,thats what i did ,i need to dust this one off and get it out and run it a while its been sitting while i was buildin the 1542 with the 23hp longtail ,but this set up really helped and can hit 20 and 21 mph B/C of it
This is east central Florida ,The footage when you see a bridge is the Halifax River , and when you see me gettin the speed on the GPS ,that's the St Johns River
Hello my friend , it is good to hear from you ,yes im surviving the COVID , and glad to hear you are as well ,and that it is about gone there ,, I have not been out on the water in a very long time ,, i hope to soon . I have been doing some much needed work on my old truck ,hopefully soon i can back out there .Thank you
Howdies ,,well i didnt do any internal engine work done ,,I got the Header from SPS ,i really like it ,and they make them ,now in not sure if they make them for ever engine or just the 14hp but its well wroth the time to contact them ,and find out if there is anyway you could get one for your engine somehow .even if they they to order one from Thailand i think its wroth the wait ,but that's me ,,but then asgain theres all sorts of things you can ,heck if you look at my last build where
what prop is that ? any idea about the weight of everything ? I just ordered a kit.. been looking at cheap 13 hp loncin or ducar 420cc engines.. I got a boat at around 150 kilos and Im 100 kg myself.. I wonder if it will plane :P Id be happy with anything above 10 knots ..
V bottom, flat bottom? Looks pretty damn cool to me! Are there plans or a kit available for that drive? I'd like to build one. It looks like allot of fun. That and you can get allot more hp out of those HF Predator engines.
I could never afford a predator engine so I got a Briggs and Stratton XC35 for £35 (lol) but ot was 150cc and only produced 3.5-4 hp. It moved the boat alright but it was a flathead and hated high rpms ( I could never put above half because it sounded like torture) and it had terrible fuel consumption being a 150cc...
then i picked up the mini filter for the vacuum from a discount auto store ,and thats it and the prop is the 8 and a 1/2 ,,i think the best thing for u may be ,something like this ,where u get a better header ,and the best carb set up for a stock engine ,and then if i were u i would jump up the the 9in prop ,you do all that and i bet you,,, you,ll see a increase ,that header was around $160 and the the whole carb set up was around $78,i should put all that in the description i think ,,,
Thank you ,i haven't been out in a while now , but Im making plans now that the weather has cooled off , ill see if i can get some new footage as well , thank you for watching
im puttin the 23hp vanguard on a 1542 tracker jon boat you see what i mean ,on that one i came up with the idea of using 30in Harley fish tails,and then i put in a old used set of stock Harley baffles,,i think there bad ass lol,,anyway then i called N R RACING,,there on line ,so i told them about the header im useing and that i want the best carb set up , in hopes of get a few HP out of the motor ,he told me to buy his Carburetor, Honda GX390, Bored (24mm) with the stack and air cleaner u see
good speed, thats about as fast as my 12 foot flat bottom boat and a 13hp. honda.with a thai clp or kkk. I allways use the engine throttle less hand strain dealing with any other throttle, usually full throttle anyway. nice vid
what size prop are you running? I got my 14hp built and ran for the first wet test, made 19mph with 2 passengers. Happy with overall speed, but im running the 8.5in prop and it felt like it had a hard time staying at the right depth in the water, felt like it wanted to climb out of the column. I have the 8 in prop and will test it out soon. Just curious what your thoughts were.
very sorry about such a late answer i think this build was a 8 1/2 , i just built a new one and it has a 8 1/2 on it now and im hitting from 15 to 18mph with all my gear but it runs along at 16 mph for the most part . the next time i go out i will be trying a 8 in , then i will upload a new video showing what if any difference there is , once again i am so very sorry for this later answer , im back now and up loading new videos as there ready so there will not be any more long waits for a answer ., on the mudmotorkit.com/ web site i think they have a answer on what to do when the motor does that , ill check also and see , and it will not be 2 years for a answer
Matt, very nice. I am going to put mud-skipper medium kit (with their 16hp) on my 1965 14ft starcraft. Do you know what speeds you were getting stock? I'm thinking around 15mph. How loud is your exhaust compared to stock. I was hoping to retrofit a car muffler so that it has the high flow but hopefully as quiet as stock (or quieter) exhaust note. Any advise there?
now this is only IMO ,but if you havnt bought the mud skipper , take a min and call SPS there number is on this web site mudmotorkit.com/ and let them explain why you should run there kits ,,, there more then happy to the answer any question you can think ,best customer service iv ever encountered ,,now i can tell you 1st hand there sps has a better design i ordered a mud skipper by mistake ,the sps kit is better, and well wroth the few extra dollars , but if you have it all ready then run it and enjoy getting out there bc the over all design of the longtail set up is great and i dont run anything else
Hey Matt was thinking about getting a bigger cam shaft and changing some stuff up to get the motor to make a lil bit more compression and was wondering if you took your governor off on your motor I know without the proper mods it can mess it up but was wondering if you took yours off thanks
very sorry for such a late reply but no the motor is stock , i changed the carb and put the header on it the header is from mudmotor.com and thats it , the carb is from NR Raceing -www.nrracing.com/ and here is the carb -www.nrracing.com/product-p/390marinecarb.htm , you must use this air fliter kit -www.nrracing.com/product-p/airfilterkit-390.htm , im back loading new videos so there will be no more wating for me to answer once again im sorry for taking so long to answer
Yah, visions of busting your own window and hot-wiring your won rig just to get home;-) nice looking motor anyway... What do you think about, the idea of; building an outboard completely from recycled/trash and bartered materials? with no real fabrication? I am developing my own 5-hp four cycle marine propulsion system the " paddle Boarder Outboard" An old push style gas mower, scrap wood and nails/screws...+a big bolt, some VERY VERY strong man made rope, and some springs/rubber tubing... the hardest part is cutting, bending and drilling the mower blade to service as an impulse arm...
what do i think ,,well i think you should go for it ,,but as you pointed out lol safety safety safety and yes would like to see it. so get footage and you load a video good luck.
Curious, what fuel mileage are you getting ?, planning a long river trip my 50hp 4 stroke gets around 10-11 mpg downstream at 25 mph 17' v bottom...if this set up can do better i would get one.
well Im sorry but i dont have any real info on this ,,thats just a small little one gallon tank ,and it just seems to run forever ...i can go out with the tank full and a small 3 gallon fuel can and run around on my backwaters all day ,thats alot of stop and go and drift fishing etc ,,,i know that wasn't much help but iv never checked how far i went on a tank full ,i will say that on the videos to come this summer i will take the time to get better info on subjects like this as well as some other topics ppl have questions on
Well i have a 23hp on a 15ft Jon-boat from Bass-pro and does great ,the Vhull helps with cuttin waves etc , but really flat bottoms are fine if not better , i haven't up,loaded videos in a while now, but im going to be getting a lot more up as soon as i can ,i found a old 12 foot v hull that i want to try this motor out on ,plus on my 15 footer im getting ready to build a front deck on it and also set it up so i can camp right on the Jon-boat ,have a few ideas like using solar yard lights at night setting up a tent on the deck as well as a type of rain protection,i don't want to go with the normal Bimini Top ,anyway once i start in on building that ill record the progress as well as the progress of bringing that 12 footer back to life,but V-Hulls vs flat bottom handle different that's all ,and your speed will always be affected by how heavy all the gear you have as well as what HP your running ,and IMO, the Flat bottom handles better ,there not made for cuttin waves but ,i hope i came close to getting a answer that helped
+Logan Cox this is fresh water out on the St Johns in Florida and that is where i go most of the time , iv ran both of em in saltwater in the Halifax river once in a while , in Thailand they run em non stop in saltwater and when the get to eat up they just throw em out , the shaft this is , there air cooled so thats the only thing in contact , well the salt air will rust things faster sure ,but anyway for as much as im in the saltwater i havnt had any issues ,if i run em in saltwater ill spray it all down with the garden hose when i get home.
Cactus Matt I noticed earlier you mentioned you used the race prepped carb from nr racing, it says choke removed on the site? Is that true? If so I'm curious the reason they remove it and how it affected cold starting or after sitting a while, as always great videos! Thanks!
no the choke is not removed , here is the carb i use www.nrracing.com/product-p/390marinecarb.htm and then you need to use this air fliter kit - www.nrracing.com/product-p/airfilterkit-390.htm - there is a Choke Lever hold down Bracket included so you remove the choke lever from the stock carb and reuse it on the new carb and the hold down bracket keeps it in place .very sorry for such a late answer , but im back now and uploading new videos so there will not be any more waiting for a answer , once again very sorry about that .
@@noflyzone13 what is the power difference from stock can you tell the difference I have the same setup on a flat bottom and been running it for years just never upgraded to carb or exhaust yet
@@jamesvaughn4747 sorry for the late reply , i can not say b/c i have never ran one stock , yet i had the same question and asked a few mechanics they all said that there is a slight increase but not much . a H/P or two from what i understand , and that anytime you allow a engine to breath easier with better fuel flow it helps , the real increases come from doing internal engine work combined with a upgraded exhaust and carb , , once again sorry for not replying sooner , i have not been able to keep up with the channel for a lil bit but i will be heading back out on the river soon looking to explore some new areas and also looking forward to building a larger v-twin set up sometime this summer ,thinking about using the the large v-twin from Harbor fright ,Even though im not a fan of having a engine that doesn't have a pull rope start on it , Ill still give a try b/c pf the the cost of the engine being a bit more affordable ,thanks for watching
sorry for late reply , yes governor is still in place , engine is stock except for the header type muffler and a new carb & high flow air filter form NR Racing
How did u get a squeeze throttle set up to work ? I have a sps long tail with 14 HP predator we found u can't get squeeze throttle to pull open throttle plate to get top speed iam running it on a 14 heavy deep v aluminum boat 64" beam this boat has 2 ft sides we managed with 3 guys a small cooler a battery extra 1 ga can of gas 15-16mph but once season came around I had to run only 2 guys with gear couldn't even get boat to plan out where looking at building a22hp surface drive now
the cable and throttle also came from SPS ,the carb & intake came from NR racing and the header also came from SPS the carb is set up to run with a header but there is nothing else done to the motor ..while i did have to keep adjusting it to get the full effect you can do it ,i really should of did a step by step on this one as well my 23hp v-twin ,as for the 23hp v-twin i still plan on doing that one ,i think possible the biggest thing was on this is making sure you have no slack in the cable as well as making sure you have the cable housing locked down tight,,in the video i mentioned how the new throttle handle really smoothed out the throttle ,i said that without explained that was important ,its b/c i also was having issues with the other options offered by SPS while they worked ok they just never seem to give my the full pull but after this was installed it made a world of difference yet i do remember having to adjust it often until i got where i wanted it im not sure if iv answered your question well enuff if not pls let me know im back now so this channel is checked often as well as videos also coming ,ill take a look at this one to see if there was any thing else i did while finding the sweet spot ,i give this away but ill be over where it is in a day or so ,At the moment im working out the details to get the 23hp taken out to 35hp ill have footage of that when it gets done
Thanks for reply yeh I called sps and they said I couldn't use there squezze throttle with 14 HP predator cuz of the throttle plate so I had to use the one that came with it which is very uncomfortable to use with heavy gloves on or even with out iam looking to put a twist style on mine or if I can some how a squeeze I've had a few problems with my sps mud kit the cable has broke and I've gone though 3 end bushings with only 16 hrs on it iam gona make a brass bushing for mine
well the squeeze throttle im using came from them unless your talking about a different kind ,but that one on there is great and had no issues bolting it on good luck
Its been a lil while ,,but Im sure i used- the Honda GX390, Race Prepped, 21 mm (Stock Bore),,when doing so it should be used with Open Element Air Filters or with Velocity Stacks.they are also on the site ,,what i ended up doing while i was trying to pick the right carb ,b/c i run the header from MudMotor as well was i called N&R he was very helpful ,,b/c i wasn't sure what it was talking about on the site when it said something about the choke could be removed ,i made sure that would not be the case ,,,he suggested that carb b/c the motor is stock yet im running the header ,
You are right it isn't the best set up but this was all I had when I built that longtail and even the ppl that sell the kits said its not the best set up for a longtail but would still get to where i wanted to go surprisingly it went very well with that 13hp haveing enuff power to get that boat up to 21 and 22 mph and here it is 2017 and that same boat and 13hp longtail is still running
Well ,i honestly do not know how properly answer that question,, im not a mechanic , but what i do on these 13 hp engines ,is change the carburetor to a 24mm Bored Carb and use a header pipe , it seems to give a boast in hp a little , i think if you can increase rpm,s (safely) then with at least this style boat motor ,meaning the longtail design ,bc the shaft bolts directly to the engines shaft then a higher rpm helps , im not a mechanic , as far as more torque ,sure i guess if it could be increased also i guess that would help,,but iv always just ran stock engines so i really dont know , but that said getting more overall power out of engine helps, not sure if that helps in answering the question ,but if i can help just ask and ill get back as soon as i can Thank You for watching,,at the moment im updating some gear needed ,working on the boat etc,, and ill be back out there soon ,got some areas i haven't been yet so Ill be uploading new video when i can .
sorry for such a late reply ,but thats a old Harley Davidson clutch lever ,just go down to a H/D shop they,ll have one ,its all i use .but sps has change the tiller arm and with that comes a new throttle design , but i still use these ,just like em better
Thanks, I managed to find that an MSR clutch lever that will fit 7/8 and 1" bars. I built a custom z-bend tiller for my mud-skipper out of 3/4" threaded pipe (lowes/home depot). It was slightly over 1" diameter but I was able to easily hollow out the MSR clutch perch to fit.
While I've got you on the horn, I got the mud skipper kit already. Only getting 14 mph out of it with the stock mud-skipper 16hp motor. Doesn't matter if I run the 8.5" prop (which handles like shit) or the 7.5" (handles really good for a longtail), I can only get 13-14mph out of it, loaded or unloaded. Next step is increase engine RPMs. Looks like you have different header, have removed governor, probably changed/drilled jets, possibly new carb but at a minimum added the air flow adapter. Is there a link to all of your mods? The mud-skipper 16 is supposedly identical to the predator
(and we have the exact same boat. mine is a 1965. What paint did you use for the seats and how is it holding up? I was going to do something similar but carpet my seats)
i will get the links for ya ,the engine is all stock, all i changed was the carb and air filter (the carb does have a different size jet)and the header type muffler ,and will get the links for ya ,as for paint ,just blue paint from home depot , oil base , i built this one back 2013 ,ended giving the whole set up boat motor and trailer away , a buddy really wanted one and i had built another give it to em but long story short its still running strong ,,,,i have a 14x42 jon now that i normally have 23hp on but just recently built another on of these kits ,same exact set up , anyway give a little bit to track down the links and will get right back with ya, iv been off line a wee bit ,but im back, plus ill be gettin back out there soon .if ya have been thinking of making a video id like to see it, .ok ill get back with soon
Sorry for such a late reply ,, the motor is stock all i did was replace the carb that i ordered from N/R Racing and the muffler .the header came from SPS Longtail ,and the carb came from NR Racing ,I do not remember right now which one i used , i ended up calling them and asking which carb i should use on a stock engine with a header and then I ordered which ever one they recommended., i will try and find out which carb i used and get back to you .Thank you for watching
@@brennanmiranda9830 Well this was my very 1st build , , somewhere around 8 years ago , I should of made a video with this set up completely stock , then another one after i changed the carb and muffler, for a comparison , but i was i hurry to get on the water , i just wasn't thinking i guess . but honestly the performance upgrade , cant really be all that much ,after all the engine is completely stock , i am no mechanic ,but it is my understanding that any time you let a engine breath easier combined with a upgraded fuel delivery ,that in doin so you gain a few horse power , i just do not have any comparison
sorry i haven't bn on here in a min need to get all th toys out and use em, but go to swamprunner.com if you still any Q,s just call them best ppl you,ll ever work with
very sorry for not answering sooner , when you buy a kit from SPS longtail / mudmotorkit.com/ everthing is included .except the motor ,you can pick from kits that are small medium and large and there is a list of motors you can use with each kit on there web site . once again very sorry for not answering sooner .
Well i dont know , guess id have to say the 15hp Yamaha would win , although Im not restricted by water depth ,so i can do the same thing you see here in 9 inches of water , but im not really worried about how fast i get to where im going . ,Thank You for watching
@@noflyzone13 it look like yamaha 15hp engine need to revive in high rpm to get more torq , and the waterpump 13hp more torq in low rpm. I thought 13hp waterpump win in swamp area and Yamaha more to upper river used.
no in fact i will be putting that on a 12 foot V-hull very very soon and well ,when done fixing up the old boat ,will videos of it performing ,speeds etc etc ,,very sorry for taking so long to get back to you ,i will be posting this summers videos from here on and be answering all questions much faster .
well these prop,s are done by size not pitch , so this one would of been the 8 &1/2 in prop , this is one of the 1st few videos i made so i didnt put any info in the video description , in the new videos i had put all the links , and prop sizes etc, , with the new build of the same set up , on a different boat
i hope that helped , but pls feel free to ask anything,,i may not had explained that good enuff im not sure,,but i will always get back to you , sometimes you may have to wait a day or two ,in fact i just spent the last few days in hospital ... no worries, doctors were just being nuisance lol , you know how they get lol ,
I'm in Cambodia and there are plenty of long tails here but I'm am doing something sorta custom. Actually I have 45' long tail w/twin deisels but I working on a 15 footer with a 16 HP motor. The parts are soooo cheap and props are $6 a piece so I can play around with size and maybe attempt to play with the pitch's but it's tricky and precise work. These mech's are quite amazing and smart too.... Let's see what happens here and I will keep you up to date and can maybe send photos. The tansom is cut below water level and engine on deck (center of gravity) but I got a trick up me sleeve Maty. Hope your better from the hospital. I avoid doctors......
oh wow , that sounds awesome . yes please keep me updated , thats one of my goals , is to have a large set up ,like what your talking about , i would set it up just they look over where your at ,all painted up and everything , im even going to put the garlands or scarves at the front of the boat i have now ,, in honour of the spirits of the water and Mae Yanang the spiritual goddess of journeys , no one here in the U.S.A. would know what or why i was doing that , but i do care what they think lol
the the drive shaft with the prop is connected directly to the horizontal shaft on the motor, please feel free to ask anything , watch this video it might help explain some things,then afer you watch it pls feel free to ask any and all questions , i really enjoy helping ,so do not ever think you are askig to many too many questions ruclips.net/video/oRO4sFbs3SA/видео.html
Well ,My Friend , im not sure what it is you are asking,,, if your asking if i was in Manaus , as in the City in Brazil ..,no i wassnt ,,, i wish ,,, i would love to visit such a beautiful area to to explore the rivers and lakes.

good ballance and surface proping the thai way!!
Freakin awesome!
Good.i like video

Id be happy with anything above 10 knots ..
Great stuff :D

I'm curious if you used a flat bottom boat vs the VHull you did what the difference would be?
Well i have a 23hp on a 15ft Jon-boat from Bass-pro and does great ,the Vhull helps with cuttin waves etc , but really flat bottoms are fine if not better , i haven't up,loaded videos in a while now, but im going to be getting a lot more up as soon as i can ,i found a old 12 foot v hull that i want to try this motor out on ,plus on my 15 footer im getting ready to build a front deck on it and also set it up so i can camp right on the Jon-boat ,have a few ideas like using solar yard lights at night setting up a tent on the deck as well as a type of rain protection,i don't want to go with the normal Bimini Top ,anyway once i start in on building that ill record the progress as well as the progress of bringing that 12 footer back to life,but V-Hulls vs flat bottom handle different that's all ,and your speed will always be affected by how heavy all the gear you have as well as what HP your running ,and IMO, the Flat bottom handles better ,there not made for cuttin waves but ,i hope i came close to getting a answer that helped
Are you running in saltwater, and if so have you had any rust problems? Thanks
+Logan Cox this is fresh water out on the St Johns in Florida and that is where i go most of the time , iv ran both of em in saltwater in the Halifax river once in a while , in Thailand they run em non stop in saltwater and when the get to eat up they just throw em out , the shaft this is , there air cooled so thats the only thing in contact , well the salt air will rust things faster sure ,but anyway for as much as im in the saltwater i havnt had any issues ,if i run em in saltwater ill spray it all down with the garden hose when i get home.
Cactus Matt I noticed earlier you mentioned you used the race prepped carb from nr racing, it says choke removed on the site? Is that true? If so I'm curious the reason they remove it and how it affected cold starting or after sitting a while, as always great videos! Thanks!
no the choke is not removed , here is the carb i use www.nrracing.com/product-p/390marinecarb.htm and then you need to use this air fliter kit - www.nrracing.com/product-p/airfilterkit-390.htm - there is a Choke Lever hold down Bracket included so you remove the choke lever from the stock carb and reuse it on the new carb and the hold down bracket keeps it in place .very sorry for such a late answer , but im back now and uploading new videos so there will not be any more waiting for a answer , once again very sorry about that .
@@noflyzone13 what is the power difference from stock can you tell the difference I have the same setup on a flat bottom and been running it for years just never upgraded to carb or exhaust yet
@@jamesvaughn4747 sorry for the late reply , i can not say b/c i have never ran one stock , yet i had the same question and asked a few mechanics they all said that there is a slight increase but not much . a H/P or two from what i understand , and that anytime you allow a engine to breath easier with better fuel flow it helps , the real increases come from doing internal engine work combined with a upgraded exhaust and carb , , once again sorry for not replying sooner , i have not been able to keep up with the channel for a lil bit but i will be heading back out on the river soon looking to explore some new areas and also looking forward to building a larger v-twin set up sometime this summer ,thinking about using the the large v-twin from Harbor fright ,Even though im not a fan of having a engine that doesn't have a pull rope start on it , Ill still give a try b/c pf the the cost of the engine being a bit more affordable ,thanks for watching
@@noflyzone13 thanks for getting back with me on that but I like mine cuz I can go anywhere and it's fun to explore with them
Where did you pick up a muffler for the predator engine?
Brandon Olzenak go power sports
Randy
Was this in alabama
Do you still have the governor in place or have you taken it out?
sorry for late reply , yes governor is still in place , engine is stock except for the header type muffler and a new carb & high flow air filter form NR Racing
What size K&N is that on the carb?
How did u get a squeeze throttle set up to work ? I have a sps long tail with 14 HP predator we found u can't get squeeze throttle to pull open throttle plate to get top speed iam running it on a 14 heavy deep v aluminum boat 64" beam this boat has 2 ft sides we managed with 3 guys a small cooler a battery extra 1 ga can of gas 15-16mph but once season came around I had to run only 2 guys with gear couldn't even get boat to plan out where looking at building a22hp surface drive now
the cable and throttle also came from SPS ,the carb & intake came from NR racing and the header also came from SPS the carb is set up to run with a header but there is nothing else done to the motor ..while i did have to keep adjusting it to get the full effect you can do it ,i really should of did a step by step on this one as well my 23hp v-twin ,as for the 23hp v-twin i still plan on doing that one ,i think possible the biggest thing was on this is making sure you have no slack in the cable as well as making sure you have the cable housing locked down tight,,in the video i mentioned how the new throttle handle really smoothed out the throttle ,i said that without explained that was important ,its b/c i also was having issues with the other options offered by SPS while they worked ok they just never seem to give my the full pull but after this was installed it made a world of difference yet i do remember having to adjust it often until i got where i wanted it im not sure if iv answered your question well enuff if not pls let me know im back now so this channel is checked often as well as videos also coming ,ill take a look at this one to see if there was any thing else i did while finding the sweet spot ,i give this away but ill be over where it is in a day or so ,At the moment im working out the details to get the 23hp taken out to 35hp ill have footage of that when it gets done
Thanks for reply yeh I called sps and they said I couldn't use there squezze throttle with 14 HP predator cuz of the throttle plate so I had to use the one that came with it which is very uncomfortable to use with heavy gloves on or even with out iam looking to put a twist style on mine or if I can some how a squeeze I've had a few problems with my sps mud kit the cable has broke and I've gone though 3 end bushings with only 16 hrs on it iam gona make a brass bushing for mine
well the squeeze throttle im using came from them unless your talking about a different kind ,but that one on there is great and had no issues bolting it on good luck
Cactus Matt Which carb and intake from NR Racing did you use?
Its been a lil while ,,but Im sure i used- the Honda GX390, Race Prepped, 21 mm (Stock Bore),,when doing so it should be used with Open Element Air Filters or with Velocity Stacks.they are also on the site ,,what i ended up doing while i was trying to pick the right carb ,b/c i run the header from MudMotor as well was i called N&R he was very helpful ,,b/c i wasn't sure what it was talking about on the site when it said something about the choke could be removed ,i made sure that would not be the case ,,,he suggested that carb b/c the motor is stock yet im running the header ,
Lol I got the same motor for a little trike I'm working on
need buy this engine 🤧
It is a 13HP Predator engine from Harbor Freight ,they are great little motors .
whats the point of that set up on a v bottom?
You are right it isn't the best set up but this was all I had when I built that longtail and even the ppl that sell the kits said its not the best set up for a longtail but would still get to where i wanted to go surprisingly it went very well with that 13hp haveing enuff power to get that boat up to 21 and 22 mph and here it is 2017 and that same boat and 13hp longtail is still running
Sometimes us smaller folk cant afford a new outboard, these mud motors are less than half the price of a similar horsepower outboard
what is best camshaft tuned for boat? do we need high rpm or more torque?
Well ,i honestly do not know how properly answer that question,, im not a mechanic , but what i do on these 13 hp engines ,is change the carburetor to a 24mm Bored Carb and use a header pipe , it seems to give a boast in hp a little , i think if you can increase rpm,s (safely) then with at least this style boat motor ,meaning the longtail design ,bc the shaft bolts directly to the engines shaft then a higher rpm helps , im not a mechanic , as far as more torque ,sure i guess if it could be increased also i guess that would help,,but iv always just ran stock engines so i really dont know , but that said getting more overall power out of engine helps, not sure if that helps in answering the question ,but if i can help just ask and ill get back as soon as i can Thank You for watching,,at the moment im updating some gear needed ,working on the boat etc,, and ill be back out there soon ,got some areas i haven't been yet so Ill be uploading new video when i can .
Cactus Matt thanks for the answer man. 😊
Matt, do you have a link to the lever you are using for the throttle? I can't find one that fits the large stock mud skipper handle.
sorry for such a late reply ,but thats a old Harley Davidson clutch lever ,just go down to a H/D shop they,ll have one ,its all i use .but sps has change the tiller arm and with that comes a new throttle design , but i still use these ,just like em better
Thanks, I managed to find that an MSR clutch lever that will fit 7/8 and 1" bars. I built a custom z-bend tiller for my mud-skipper out of 3/4" threaded pipe (lowes/home depot). It was slightly over 1" diameter but I was able to easily hollow out the MSR clutch perch to fit.
While I've got you on the horn, I got the mud skipper kit already. Only getting 14 mph out of it with the stock mud-skipper 16hp motor. Doesn't matter if I run the 8.5" prop (which handles like shit) or the 7.5" (handles really good for a longtail), I can only get 13-14mph out of it, loaded or unloaded. Next step is increase engine RPMs. Looks like you have different header, have removed governor, probably changed/drilled jets, possibly new carb but at a minimum added the air flow adapter. Is there a link to all of your mods? The mud-skipper 16 is supposedly identical to the predator
(and we have the exact same boat. mine is a 1965. What paint did you use for the seats and how is it holding up? I was going to do something similar but carpet my seats)
i will get the links for ya ,the engine is all stock, all i changed was the carb and air filter (the carb does have a different size jet)and the header type muffler ,and will get the links for ya ,as for paint ,just blue paint from home depot , oil base , i built this one back 2013 ,ended giving the whole set up boat motor and trailer away , a buddy really wanted one and i had built another give it to em but long story short its still running strong ,,,,i have a 14x42 jon now that i normally have 23hp on but just recently built another on of these kits ,same exact set up , anyway give a little bit to track down the links and will get right back with ya, iv been off line a wee bit ,but im back, plus ill be gettin back out there soon .if ya have been thinking of making a video id like to see it, .ok ill get back with soon
whats all done to the motor rebuild wise
Sorry for such a late reply ,, the motor is stock all i did was replace the carb that i ordered from N/R Racing and the muffler .the header came from SPS Longtail ,and the carb came from NR Racing ,I do not remember right now which one i used , i ended up calling them and asking which carb i should use on a stock engine with a header and then I ordered which ever one they recommended., i will try and find out which carb i used and get back to you .Thank you for watching
@@noflyzone13 no problem man thanks for the reply can u tell the performance difference with the upgrade
@@brennanmiranda9830 Well this was my very 1st build , , somewhere around 8 years ago , I should of made a video with this set up completely stock , then another one after i changed the carb and muffler, for a comparison , but i was i hurry to get on the water , i just wasn't thinking i guess . but honestly the performance upgrade , cant really be all that much ,after all the engine is completely stock , i am no mechanic ,but it is my understanding that any time you let a engine breath easier combined with a upgraded fuel delivery ,that in doin so you gain a few horse power , i just do not have any comparison
what I need to build a machine like that. where you get the parts from
sorry i haven't bn on here in a min need to get all th toys out and use em, but go to swamprunner.com if you still any Q,s just call them best ppl you,ll ever work with
plus feel free to ask me anything as well
how did you mount it to the transom?
very sorry for not answering sooner , when you buy a kit from SPS longtail / mudmotorkit.com/ everthing is included .except the motor ,you can pick from kits that are small medium and large and there is a list of motors you can use with each kit on there web site . once again very sorry for not answering sooner .
13hp waterpump engine vs outboard yamaha 15hp who will win
Well i dont know , guess id have to say the 15hp Yamaha would win , although Im not restricted by water depth ,so i can do the same thing you see here in 9 inches of water , but im not really worried about how fast i get to where im going . ,Thank You for watching
@@noflyzone13 it look like yamaha 15hp engine need to revive in high rpm to get more torq , and the waterpump 13hp more torq in low rpm. I thought 13hp waterpump win in swamp area and Yamaha more to upper river used.
what length shaft did you go with ? 85 or 100
on that kit they are 85
Thanks
What size prop are you running?
that is the 8 & 1/2 prop
Please tell me if that's a 15" or 20" transom?
dale3858 ,,heck i dont know ill have to check ,,,just give me a lil,, i get back with ya i promise
15 , very sory for such a later answer ,
dua hom
Would that motor b to much on a 12 ft?
no in fact i will be putting that on a 12 foot V-hull very very soon and well ,when done fixing up the old boat ,will videos of it performing ,speeds etc etc ,,very sorry for taking so long to get back to you ,i will be posting this summers videos from here on and be answering all questions much faster .
What's the prop pitch I am doing the same right now
well these prop,s are done by size not pitch , so this one would of been the 8 &1/2 in prop , this is one of the 1st few videos i made so i didnt put any info in the video description , in the new videos i had put all the links , and prop sizes etc, , with the new build of the same set up , on a different boat
i hope that helped , but pls feel free to ask anything,,i may not had explained that good enuff im not sure,,but i will always get back to you , sometimes you may have to wait a day or two ,in fact i just spent the last few days in hospital ... no worries, doctors were just being nuisance lol , you know how they get lol ,
I'm in Cambodia and there are plenty of long tails here but I'm am doing something sorta custom. Actually I have 45' long tail w/twin deisels but I working on a 15 footer with a 16 HP motor. The parts are soooo cheap and props are $6 a piece so I can play around with size and maybe attempt to play with the pitch's but it's tricky and precise work. These mech's are quite amazing and smart too.... Let's see what happens here and I will keep you up to date and can maybe send photos. The tansom is cut below water level and engine on deck (center of gravity) but I got a trick up me sleeve Maty. Hope your better from the hospital. I avoid doctors......
oh wow , that sounds awesome . yes please keep me updated , thats one of my goals , is to have a large set up ,like what your talking about , i would set it up just they look over where your at ,all painted up and everything , im even going to put the garlands or scarves at the front of the boat i have now ,, in honour of the spirits of the water and Mae Yanang the spiritual goddess of journeys , no one here in the U.S.A. would know what or why i was doing that , but i do care what they think lol
Where you find that headermuffler lol no other name to call it lol
sorry for such a late reply, but i bought that from the ppl at SPS Longtail
Sorry, mais comment avoir de la puissance sans boite de vitesse! Sinon, super le GPS good idea!
the the drive shaft with the prop is connected directly to the horizontal shaft on the motor, please feel free to ask anything , watch this video it might help explain some things,then afer you watch it pls feel free to ask any and all questions , i really enjoy helping ,so do not ever think you are askig to many too many questions ruclips.net/video/oRO4sFbs3SA/видео.html
