I would like to thank you for your videos. I have now converted my 15hp to 20hp and done all service tasks guided by your videos (never before have I done anything myself to my outboard) . Have a nice upcoming summer!
Thanks for all your intuitive videos on the 9.9 Suzuki. You did a great job on all of them. Your very motivated. Looks a little violent and overpowered with the 20 conversion. Almost Scary Fast. Another reason to have the 9,9 with conversion is for lakes that only let us run 10 hp max.
Yes its scary fast i dont run it full throttle all the time. Sure is overpowered but i like the fast takeoff get on plane so quick and stay at a cruising speed of 22mph max most of the time. Its nice to have the extra horses hahaha
Got to test the 20hp upgrade on my zk430 14' kaboat. I was averaging 26 mph with a top speed of 28 mph with me and my 6 year old son inside. I was using the 11 pitch solas alum prop. It is rock solid stable in this boat, which is a bit wider than the standard kaboat but also has the inflatable v-keel. Was able to even go WOT over some chop. I am very happy with the setup
Thanks again, I got my new Suzuki 9.9 out yesterday for the first time, on my heavy 14' jon boat. I need the extra horsepower as it barely gets on plane at 13 mph with just me aboard and the standard 9" pitch propeller. I wasn't even in the ideal rpm range at WOT. So I ordered the parts! It was also good to see your video and hear that your motor has the same whine that mine does. I was thinking something was wrong and even checked the lower unit just to make sure it had fluid in it.
@@laingej What is the maximum motor power indicated for your pneumatic boat ??? I have one very similar to your, 10.5 feet (3,20 meter) with a 20 HP top limite, and she flies and glides perfectly and safely at that speed.
Great videos. Without them I wouldn't have bought the Suzuki. I had to see someone solo put together the boat from the back of a truck to commit to it. I got my Zk430 in the water today with the stock 9.9 and it worked great. I am a strong guy, 6'4" 220, and it was still difficult to handle the motor out the back of my Yukon. It's awkward going sideways to vertical I almost dropped it lol.
Thank you for your vids. Based on them bought a base 20HP Suzuki in white. Nothing else on the internet came close describing what this motor is like inside and out. Very helpful.
Pff lol 18hp evinrude here cost 200$ with the fuel tank. Gets up to 25mph on my 12ft jon boat. No mods if I put a better prop on and trim the motor right I'll be able to touch the 30s easy. My entire setup has cost me less than $700 meanwhile u can't even buy one of these new for that
I've got a 15 hp Suzuki I'm considering upping to 20 after I saw another video about how simple it was but no one has mentioned the valve clearance. Adjusting the valve clearance is not a simple procedure and I have to wonder if the clearance is the same when you change the capacity of the motor. Seems like the water pump could be an issue as well. How is the motor doing after two years?
Was wondering what length your tiller extension is? I'd like to have a standing setup like yours but would need to move it quite a bit forward like you...
@@laingej Good engine i have same 20Hp great power and fuel economy on them engine. Solas amita 10 pitch best solution my 4.3 dinghy. I have removed hidrofoil big increases in speed as hidrofoil creating to much drag, boat takes few second slower to get plane but top speed way better. Your boat looks narrow so its harder to plain without hidrofoil. Its possible to get 50km/h speed with no hidrofoil.
I have the same exact engine but on a 1448 Grizzly tracker I'm debating whether to go up to the 11 if I got the 10 do you think the boat style it's South since it's different than yours makes a difference??
Man sorry about the loss! I just got a new motor…I got the 20… gonna put it on a 12’ Gregor…I’m wondering you think I should go to the 11” prop? Do you know what your idle speed happened to be?
Barefoot? You’re one tough hombre. I have a 20hp Tohatsu on a14 foot Bris with an aluminum floor and I only get about 21mph at max rpm. I guess on the bright side I didn’t lose my fish finder. Nice video.
I’m considering a 6hp just for the weight savings but really do want the efi, power, tilt trim, smoothness etc of your motor. How do you transport the outboard around? Do you pick it up and put in your vehicle by yourself? That’s heavy work?
I considered the 6hp too. Though about it for months. Save $$ for the 9.9 totally worth it. The 6hp is a maxed out 4hp. Carb gives staring problems with tine. Its louder single cilinder vibrates more. The 9.9 is 40 pounds heavier. I pick it up by my self 100 lbs lay it on its side on the back of my truck. I wheel the boat as close as possible to the truck so not hard at all.
It was my fault .. i didnt clip it right.. had the clip backwards.. the quick release. Realized that when i got the new one and i paid attention to the instructions 😅
I just bought a New Suzuki 25 hp with elec start,tilt /trim. How much of a job was it to hook up to engine to get speed and RPM readings? Sorry about your loss, I will secure mine better hopefully.🤔
Thanks for showing your results from the prop changes. I'm getting about 24 mph with my 20 hp Tohatsu on my 12' Mars with 2 people and about 27 mph riding solo. I'm running the stock prop, not sure what pitch it is. It's really cool how you upgraded your 9.9 to a 20. I was curious about how to do it. Can't believe it's so simple. I think the 20 hp cost about $1000 more than the 9.9, which is crazy considering they're basically the same engine with a different tune. I have a 200 Honda on our tritoon which is the same engine as the 225 and 250. I wonder how much it would cost to upgrade it to a 250? I'll have to look into that.
@@ariebakhuizen5486 I believe the main thing, perhaps the only thing, is the ECU retune. The prop would be a separate thing to consider. You should do a search for "prop sizing" which would explain how to determine which prop you need. (I'm not an expert, but your basic goal is to dial in the correct engine RPM at top speed.)
Actually it was my fault it .. hard to explain but i had the mount upsidedown backwards on this model fish finder posible to do this mistake and the locking clip is not the best so the weight on the device itselft boncing can come off if its backwards so its a desing flaw but i didnt read the instructions. I got me a new one same one but the plus model. The mound is the same i make sure i have it the correct way (release clip down) and no problems wont come off.
we have a similar setup. converted 9.9 to 20 hp suzuki. 12ft saturn hd fishing inflatable. 2024 models. on a smooth lagoon with the original 9 pitch prop, i could only get 19mph. i spun the sola 10 pitch and am wondering if i could get more speed with it? or, is 19 the max i can get with 2 men [400 lbs]. any suggestions how high or low to mount the motor. i put a 1" block to raise the motor. i ran with and without the block and it made no difference. i ran with hydrofoil and without, no difference. just would like to get 25mph if possible. trim position 1 was the best results. with position 2 and 3 i hit the rev limiter. thoughts? and thanks for your vids! in the vid you typed the 9 pitch stock prop was 24mph. you also said the 10 pitch got 26 mph. an increase from 18mph. what setup was the 18mph result?
Enjoy the in-depth video series. Have you tried stainless steel? Maybe a future video to see if you gain speed or smoothness with it over aluminum same pitch.
Do you still run the 11 pitch prop? I too have a Suzuki DF20 that came with a 9.25 10 pitch. I was getting around 5800 with two peop at wot. We have a Truekit Discovery 4.0 meter caterman style pontoon like yours. (13 feet). I tried a 4 blade 9 pitch with four people but hit the rev limiter at around 6330. I noticed more vibration with the aftermarket Silas 4 blade in the tiller handle. I was thinking about going with the branded suzuki 11 pitch for one or two people. What are your thoughts
Yeah i still run the 11” prop but mostly im using my 10” because i like its faster acceleration and dont need the top end of the 11” . The 11 is going to be slower take off but higher top speed. And in my case a hydrofoil is needed with the 11” prop because it ventilates without it sometimes to close to surface for that high pitch. The 10 i can use without hydrofoil no problem. The suzuki props are better than solas more price thou. I use the 11 when i go by myself and want to go fast wot. I only tried one 4blade solas 7” prop once.. and was similar in performace to the 9” 3 blade solas. I did hit redline but no vibrations.. every boat is different i bet that 9” prop four blade would do fine on my boat. Its tricky you really need to try based on the data you have. Try the 11” suzuki let me know
@@laingej so I picked up a 9x9 prop from Turning Point called the Hustler. There clams to fame is a more cupped prop with more efficient exhaust. Unlike the Solas products the hub is not included. I am waiting for that to come in. I will do a review and let you know. I am betting that I will get closer to 6k without over rev
Awesome so cool, Thank you! Can i ask a question is the exu same in the 9.9 and the 15 hp? Is the the difrence only in the restrictor plate? THANK YOU!
I have the same motor as you that I used you video to upgrade it to 20hp and on my kaboat, I'm getting what feels to be large air pockets getting caught under the air floor and are making their way back to the prop. Have you had any of these issues?;
What is the maximum motor power indicated for your pneumatic boat ??? I have one very similar to your, 10.5 feet (3,20 meter) with a 20 HP top limite, and she flies and glides perfectly and safely at that speed.
Max hp stamped on the plate is 9.9 but the website says its rated for a 15hp i wrote Them an email asking boatstogo and they told me yeah its rated for a 15 but people always go higher so if they stamp a 15 people will be putting a 25hp lol so they stamped it with a 9.9 and people puts on a 20hp lol.. yeah it handles fine a 20hp
@@laingej that is the Most Incredible !!! In Europe if one puts a superior power outboard motor in relation to the appropriate power to the boat... the only thing to expect, is to LOOSE the motor and get a Mulct, because there is no way to make a boat's Registration With a non Authorized Power mounted, and sailing with a non registered motor, it's asking for the Great Mulct, from 350 to 3500 US Dollar (300 to 3000 € ) AND SEIZED MOTOR !!! Unless you upgrade it After Registration, of course !
Never mind, I found the answer below "im afraid you cant.. 2010 thats the A series carburated model.. you can do this on the 2014 up fuel injected B series" It helpful others with older these motors are S.O.L. Thank you
So in the end what prop did you stick with? I'm going to do the upgrade to my motor from 9.9 to 20hp. This will be for a pontoon boat on a low hp lake. What prop size would you recommend? Thanks for the videos by the way...these have been a great help to me.
I use the 10” prop most of the time because its the right in the middle both 9.9 and 20hp can run it at a good rpm range. Both are fine 11” or 10” but my boat is small so you might be better of with the 11”
@@laingej That's the direction I was going to go but I wanted to get your thoughts as you've done the prop comparisons. Did you stick with the Solas or did you try the Suzuki props? Thanks for your input.
@@ML-vc8zs i have not tried a susuki 11” some people in forums claim they are better. I dont know if thats true. I got the suzuki 9” the 10” and 11” are solas. If there is a difference it has to be small i got no complain on solas. Very well maid. I tell you one thing the susuki prop seems softer alluminum i got a couple nicks on the 9” while nothing on the solas. Just a little paint wearing off.
Just wondering what altitude you're running at... It really makes a HUGE difference in motor performance. You lose a lot of hp when you go up high. You need to prop it differently at altitude as well. I'm wanting to put things in context, so I can figure out what to go with (both hp and prop) at 5000-9000 feet.
What you mean? Like spacer or washers? No ..fits fine with the stock washer and nut .. you could use a thicker washer just so castle nuts ends closer to the cutter pin but its fine.
The latest DF9.9AL comes with a 7"-11"P Propeller & the latest DF20AL comes with a 7"-12'P Propeller. If you want to improve you could go to a Suzuki Propeller - 8-20HP, Dia 9 1/4", Pitch 11" or Suzuki Propeller - 8-20HP, Dia 9 1/4", Pitch 12".
I have a 6hp 2 stroke on my sk470xl, .. question??, should i add a stabilizer to the outboard and in all honest, how well does the kaboat do in semi rough ocean conditions?, plans are to get out to our islands that are 11mi, 17 mil, and another is 23 miles out, your thoughts?, and thank you for your input!!!
I have not put mine on saltwater yet but should not have a problem in the ocean. I dont think you need a hydrofoil with a 6hp.. but you can try. it might get on plane faster.
U know im have same thoughts, Have only run my motor through full break in and then a few more hrs,, Its about weight and putting it up front so you will get up on plane faster, Ive made a 2 ft extension to use on the throttle and steering, putting me up twards the middle of the boat
Thats because they been making the 9.9 much longer since the 90’s theres so many models that now the 9.9 is in the B series. The 20 is still with the A . The 9.9 A is carburated
@@laingej thank you for answer. Some lake in Poland have 10hp limit but on riwer i need some ekstra power and its great solution IF you wouldn't buy 2 engine. Anyway your movie on yt about engine is The best.
Can you please publish the full Model Code Sequence of your engine, with elect start, and Tiller steer wit 15" shaft, etc? I believe what you have is a DF9.9B series at is in the same class as the DF20A and DF 15A. I notice that there is a DF9.9A series which is in a different model group. Please clarify what you have. Please include the codes that follow the B Series designation. Thanks. Your videos sold me on getting a new Suzuki!.
I have the df9.9bthl2. I only changed the flash back arrestor and put a solas 11pitch stainless prop on it. Went from 12-15mph to 22-25mph on a 1442 grumman rogue flat bottom.
@@bassmankelly1744 you changed the flash back arrestor or removed it? If you changed it how so? That is an impressive gain Suzuki must have the exhaust very restricted.
@@jaridfuller2450 i removed the 9.9hp restrictor plate on the intake and replaced it with the flame arrestor for 20hp. There are videos on RUclips that show you how to do it.
You need a wider boat and more weight up front, the kaboat is too unstable to truly appreciate the power of a 20hp outboard. Awesome upgrade on the motor though!
@gowdaflow thanks! Yes, only on calm waters and with the hydrofoil on ..i can open it all the way.. its overpower for the kaboat but i dont think im steping back down to the 9.9 😅.. the take off is still great i dont have to run full speed all the time.
I feel it helps with handling.. feels more stable when steering ride flatter less tilting. Get to plane quicker and Doesnt affect speed in my case but the say on bigger boats make them slower
@san update: i took it out today without the hydrofoil and huge difference decreased performance. Slower to plane ..and easily oversteering at high speed, im putting it back and leaving it on for the 20hp. Setup. when it was a 9.9 didnt make much difference but helps alot handling the extra power

@ju depends on your boat size weight and hull too. Some people with ribs v hull go faster others slower but i love the power it has more that stop speed. It accelerates faster. O-to plane speed in a few seconds
Fue mi culpa no lu puse bien el gps. Compre otro modelo mejor. Si 20mph es la velocidad que lo corro mas rapido es peligroso esto no pesa despega como un avion 😅
LaingEj si para que mas ,,, lo compre para moverve cerca en los canales de la bahia de biscayne y ni tengo que mover el bote y tener los 300 encendido yo me e ahorrado horas y gasolina con el dinghy ,,,,
deep blue channel si muy buena idea! Yo vivi en west palm beach todavia tengo familia aya un dia de estos llevo el kaboat mio para pescar en agua salada.. me gusta spearfishing que haces yo hacia eso en honduras con arpones caseros que yo fabricaba
It could not handle the bumpy ride.. the mount is a cheap design from garmin’s part ..comes off easy and moves.. i will get a the same one but strap it down next time. Its a good unit with gps.
Glad to know i wont be wasting my time with that conversion, ill convert a 15hp to 25 any day. But this is just a waste of time, just buy a bigger motor to start with.

Looks a little violent and overpowered with the 20 conversion. Almost Scary Fast.
Another reason to have the 9,9 with conversion is for lakes that only let us run 10 hp max.
Yes its scary fast i dont run it full throttle all the time. Sure is overpowered but i like the fast takeoff get on plane so quick and stay at a cruising speed of 22mph max most of the time. Its nice to have the extra horses hahaha

I am waiting for that to come in. I will do a review and let you know. I am betting that I will get closer to 6k without over rev
Awesome so cool, Thank you! Can i ask a question is the exu same in the 9.9 and the 15 hp? Is the the difrence only in the restrictor plate?
THANK YOU!
A meant to say the ecu, not the exu😊
Ecu for the 15 is different. Lets you rev higher to 6000 rpm
I have the same motor as you that I used you video to upgrade it to 20hp and on my kaboat, I'm getting what feels to be large air pockets getting caught under the air floor and are making their way back to the prop. Have you had any of these issues?;
You need to pump your floor up more or place a small 3/8 sheet of plywood under your floor at the stern to stop the bowing and air pocket
I have a 15 hp Suzuki .. 2017 model. My question is, can I also convert mine to a 20hp by doing the same thing you did?
Yes you can. Just need the 20ecu and flame arrestor.
What is the maximum motor power indicated for your pneumatic boat ??? I have one very similar to your, 10.5 feet (3,20 meter) with a 20 HP top limite, and she flies and glides perfectly and safely at that speed.
Max hp stamped on the plate is 9.9 but the website says its rated for a 15hp i wrote
Them an email asking boatstogo and they told
me yeah its rated for a 15 but people always go higher so if they stamp a 15 people will be putting a 25hp lol so they stamped it with a 9.9 and people puts on a 20hp lol.. yeah it handles fine a 20hp
@@laingej that is the Most Incredible !!!
In Europe if one puts a superior power outboard motor in relation to the appropriate power to the boat... the only thing to expect, is to LOOSE the motor and get a Mulct, because there is no way to make a boat's Registration With a non Authorized Power mounted, and sailing with a non registered motor, it's asking for the Great Mulct, from 350 to 3500 US Dollar (300 to 3000 € ) AND SEIZED MOTOR !!! Unless you upgrade it After Registration, of course !
Great Video. Question.. does anyone know the 'oldest year' Suzuki 9.9 that the '20 hp conversion' can be done successfully?
Never mind, I found the answer below "im afraid you cant.. 2010 thats the A series carburated model.. you can do this on the 2014 up fuel injected B series" It helpful others with older these motors are S.O.L. Thank you
Gutted for you bud hope you're get enough people watching so you can get a new one ;).
So in the end what prop did you stick with? I'm going to do the upgrade to my motor from 9.9 to 20hp. This will be for a pontoon boat on a low hp lake. What prop size would you recommend? Thanks for the videos by the way...these have been a great help to me.
I use the 10” prop most of the time because its the right in the middle both 9.9 and 20hp can run it at a good rpm range. Both are fine 11” or 10” but my boat is small so you might be better of with the 11”
@@laingej That's the direction I was going to go but I wanted to get your thoughts as you've done the prop comparisons. Did you stick with the Solas or did you try the Suzuki props? Thanks for your input.
@@ML-vc8zs i have not tried a susuki 11” some people in forums claim they are better. I dont know if thats true. I got the suzuki 9” the 10” and 11” are solas. If there is a difference it has to be small i got no complain on solas. Very well maid. I tell you one thing the susuki prop seems softer alluminum i got a couple nicks on the 9” while nothing on the solas. Just a little paint wearing off.
Just wondering what altitude you're running at... It really makes a HUGE difference in motor performance. You lose a lot of hp when you go up high. You need to prop it differently at altitude as well. I'm wanting to put things in context, so I can figure out what to go with (both hp and prop) at 5000-9000 feet.
Do you need any accessories/hardware for the solas 10” prop in order for it to fit on the 9.9?
What you mean? Like spacer or washers? No ..fits fine with the stock washer and nut .. you could use a thicker washer just so castle nuts ends closer to the cutter pin but its fine.
Thanks. I just ordered the parts for my 2016 9.9... ordered the ecu and flame arrestor for the 2016 20A
The latest DF9.9AL comes with a 7"-11"P Propeller & the latest DF20AL comes with a 7"-12'P Propeller. If you want to improve you could go to a Suzuki Propeller - 8-20HP, Dia 9 1/4", Pitch 11" or Suzuki Propeller - 8-20HP, Dia 9 1/4", Pitch 12".
I have a 6hp 2 stroke on my sk470xl, .. question??, should i add a stabilizer to the outboard and in all honest, how well does the kaboat do in semi rough ocean conditions?, plans are to get out to our islands that are 11mi, 17 mil, and another is 23 miles out, your thoughts?, and thank you for your input!!!
I have not put mine on saltwater yet but should not have a problem in the ocean. I dont think you need a hydrofoil with a 6hp.. but you can try. it might get on plane faster.
@paul, I'm local to you and have similar goals for my kaboat, you want to trade notes? I could benefit as I'm pretty green
U know im have same thoughts, Have only run my motor through full break in and then a few more hrs,, Its about weight and putting it up front so you will get up on plane faster, Ive made a 2 ft extension to use on the throttle and steering, putting me up twards the middle of the boat
How did you make the tiller extension? It looks awesome.
I got a video for it ruclips.net/video/zOILfEvqOlk/видео.html
Do you put this video on when you’re heading out to go dancing at the club?
Hello. Great video. I have the 2010 suzuki 9.9 hp 4 stroke. Can I convert mine to 20 hp? Thanks.
Hey thanks.. im afraid you cant.. 2010 thats the A series carburated model.. you can do this on the 2014 up fuel injected B series
@@laingej thank you bro :(
Whats the difference between the letter B amd The A. After the 20 there is a A and after the 9.9 there is a B why is that?
Thats because they been making the 9.9 much longer since the 90’s theres so many models that now the 9.9 is in the B series. The 20 is still with the A . The 9.9 A is carburated
LaingEj thank you very much!
liked n sub
What was the approximate cost of the parts to make it into 20 hp?
$417 exact cost
So you improved the 99 to a 20? I have a 25 and would like to make it a 30. How do yo do it?
Yes, you can do it to with the newer models .. 25 and 30 same motor. As easy as this swapping few parts
I'd like to see that motor on a sea eagle fast cat 14
How much you pay for the boat?
Hello, is beter engine 9,9 i can change to 20hp Then suzuki? Will you buy again suzuki?
@piotr i love my suzuki. Definitely will buy it again. Yeah you can get the 9.9 then convert to 20
@@laingej thank you for answer. Some lake in Poland have 10hp limit but on riwer i need some ekstra power and its great solution IF you wouldn't buy 2 engine. Anyway your movie on yt about engine is The best.
My AB glass vbotton and a yamaha 15hp 2 stroke does 39mph.
What’s the max rpm rating on that as a 20hp?
6300 rpm as a 20hp
Can you please publish the full Model Code Sequence of your engine, with elect start, and Tiller steer wit 15" shaft, etc? I believe what you have is a DF9.9B series at is in the same class as the DF20A and DF 15A. I notice that there is a DF9.9A series which is in a different model group. Please clarify what you have. Please include the codes that follow the B Series designation. Thanks. Your videos sold me on getting a new Suzuki!.
Df9.9bes2
I have the df9.9bthl2. I only changed the flash back arrestor and put a solas 11pitch stainless prop on it. Went from 12-15mph to 22-25mph on a 1442 grumman rogue flat bottom.
@@bassmankelly1744 you changed the flash back arrestor or removed it? If you changed it how so? That is an impressive gain Suzuki must have the exhaust very restricted.
@@jaridfuller2450 i removed the 9.9hp restrictor plate on the intake and replaced it with the flame arrestor for 20hp. There are videos on RUclips that show you how to do it.
@@jaridfuller2450 restrictor is not it the exhaust its on the intake manifold
You need a wider boat and more weight up front, the kaboat is too unstable to truly appreciate the power of a 20hp outboard. Awesome upgrade on the motor though!
@gowdaflow thanks! Yes, only on calm waters and with the hydrofoil on ..i can open it all the way.. its overpower for the kaboat but i dont think im steping back down to the 9.9 😅.. the take off is still great i dont have to run full speed all the time.
What trim position do you usually use?
The outboard trim position? The very last pin hole. All the way down.
@@laingej ok. Thank you. If you had 4 adults would you prop down to 9 or 8 pitch?
DF20 in stock goes with 12 pitch prop. Try it, you will be surprised...
Have not tried a 12 pitch on this boat. it will spray too much water. The 11 sprays alot maybe because of the tubes extending on the back
All that for only 22mph? My 12ft jon boat with an 18hp evinrude gets up to 25mph and i haven't even changed the prop or got the trim dialed in yet
Did you think that the hyrda foil helps? Good video mate
I feel it helps with handling.. feels more stable when steering ride flatter less tilting. Get to plane quicker and Doesnt affect speed in my case but the say on bigger boats make them slower
@san update: i took it out today without the hydrofoil and huge difference decreased performance. Slower to plane ..and easily oversteering at high speed, im putting it back and leaving it on for the 20hp. Setup. when it was a 9.9 didnt make much difference but helps alot handling the extra power
@@laingej that's really interesting.
LaingEj good to know that the foil helps.
@LaingEj what hydra foil did you get?
Nice I have same setup. Are you on any of the inflatable boat Facebook groups?
You know what, im not.. im in a couple kayak groups because i had kayaks before but i will look for inflatable groups to join
@@laingej I am having trouble finding some launch wheels for mine. Are you using any?
Kacper Nowotynski yes you can see them in my other video ruclips.net/video/1pR_qjMFXrk/видео.html min 6:43

@@laingej nice I was looking at those. I ordered the seamax ones but I was worried that they won't fit, the engine turns quite a bit left to right.
So you get about 50% more speed for 100% more hp? I guess that’s normal right, given the other non motor variables?
@ju depends on your boat size weight and hull too. Some people with ribs v hull go faster others slower but i love the power it has more that stop speed. It accelerates faster. O-to plane speed in a few seconds
Man that sucks! Cool video tho!
Go with a 10 inch stainless your best bet
il keep my aluminum v that rubber ducky flops all over
Basically you increased your speed by 50% by changing the prop.
Not just the prop alone, engine was deresteicted. Replacing ecu. Went From 9.9hp to 20hp
@@laingej: Yeah, I knew that from your other video...Great Job!!!
esa velocidad esta vien para que mas .....se perdio el gps para la proxima hay que ponerle un flotador
Fue mi culpa no lu puse bien el gps. Compre otro modelo mejor. Si 20mph es la velocidad que lo corro mas rapido es peligroso esto no pesa despega como un avion 😅
LaingEj el dinghy nuebo que tengo es de piso de aluminio duro y coje con el yamaha 8hp 17 millas y va en el aire camina vien con el mar en calma😀
Que bien corre buena velocidad mas que suficiente 👍
LaingEj si para que mas ,,, lo compre para moverve cerca en los canales de la bahia de biscayne y ni tengo que mover el bote y tener los 300 encendido yo me e ahorrado horas y gasolina con el dinghy ,,,,
deep blue channel si muy buena idea! Yo vivi en west palm beach todavia tengo familia aya un dia de estos llevo el kaboat mio para pescar en agua salada.. me gusta spearfishing que haces yo hacia eso en honduras con arpones caseros que yo fabricaba
Crikey...I'm get 16 mph with a 6 hp 4-stroke Merc on a SK385XL...
Nice! good setup. Power to weight ratio. almost matches the 9.9hp on the sk470xl does 18mph
Throttle not trottle
Brilliant observation
All this experimenting so that we won't have to and you lost your fish finder.... So sorry man.
It could not handle the bumpy ride.. the mount is a cheap design from garmin’s part ..comes off easy and moves.. i will get a the same one but strap it down next time. Its a good unit with gps.
Glad to know i wont be wasting my time with that conversion, ill convert a 15hp to 25 any day. But this is just a waste of time, just buy a bigger motor to start with.
CAN'T BACK UP A TRAILER ? lol
that transom sucks
What a waste of time that was.
