- Опубликовано: 5 сен 2024
- Today we finally get to finish the video series on the Swamp Rat. This was a 14' flat bottom jon boat that we installed the Mudskipper 7.5hp surface drive kit on. We then built the engine with a performance cam, billet rod, billet flywheel, upgraded valve springs, and Mikuni carb. The engine doubled its Hp but how did it perform on the water? Stay tuned to find out!!!

Braxton got one hell of a deal on his trade. That stratos with that engine is capable of 70 mph and a good rig. As for the mud motor yes it needed to be propped to wrap in the power band at wot.
Sounded to me like you had too much pitch on the prop to let the RPM come up. A lower pitch prop would let the RPM come up and put less stress on the belt. Also you would get a better hole shot and more likely more speed. Kind of like changing gear ratios.
True, the prop is a major tuning tool in a boat. Diameter/pitch/number of blades/blade shape. The prop needs less diameter and or pitch to get the rpm up on the motor, then you’ll know the true potential with that motor.
If your building a mud motor, i suggest beaver dam stuff. Ive had a 6hp mudskipper for 10 years and recently got the beaver dam for a 440 duro and its built way better.
Welcome back I kind of missed you guys it's been a long time almost about a year and a half like to see this on the boat see how it goes
They never wen't away. But maybe you did? So welcome back to you.
Ready to see yours!!!
It was great to see Skidmark back in the shop,and to know he's doing well. Miss that smile and the fun addition to the chatter.
Big v twin build 999cc can't wait to see the hp figure when you get round to it
Im really excited to see your boat build
I 100% agree with what you say I went down the same road built a motor was to much for the kit went and got one with electric start does just fine for duck hunting.
Can I suggest asking Matts Offroad Recovery to join you at Winrock for a collab? or would the big vehicles place the smaller ones at risk?
Your videos are awesome.Keep up the great work.I put a 212 on a kayak but the fake mikuni carburetor was acting up so I was only able to go full speed and when I slowed down it will shut off.
I've been looking at doing this Wednesday on a cheapo aluminum boat for the heck of it.
your rite about the RPM vs.hp limit etc.. with these 212's on the water.. Theres a certain point of no-return with these engines in the water world..
youll get too a point, were more hp, rpm, more power, different props, really wont make more speed.. Theres certain sweet spot' that is different on every setup.
I tried different style props, sizes, more rpm, more cam, more carb, more exhaust, and i never did get over my 20 mph goal "(with my flat bottom 10ft boat) my best was 18mph, and at 4800rpm.. and im happy with that for now..
your rite about every thing you said with top speed (with this motor drive setup anyway)
Ive heard the only true way too get more speed, is a TRUE -LONGTAIL, and or, a big block.etc.
you need too get the prop figured out, and get it back farther behind the boat, like they do in Thailand. and then power and rpm will make more speed.. also theboat design, andthe wake it makes behind it..andwere the prop is in the water etc..
Because these "shorttail motors hit a limit.
real lean should be around 12s
I wanna see Isaac bang John or Charles bang John or a 3 sum between them that would RULE 😂
A predator 224 stage one with billet rod shaved head valve job and ratio rockers would be perfect
A year ago 😳man duh time flies ☮️
Sir the red beard code does not work for me on go power sports
lets see some more 212-clone water builds.... try changin props and try a true' LONGTAIL.
He's a grown young man now damn I feel old I know you do
HP = How hard you hit the wall.
TQ = How far you take the wall with you.
Amen
The broken belts sound like a bummer, especially since one broke even on the stock motor. I really wish these kits were chain driven.
Do yall do builds for customers
I wanna see John get freaky with Isaac
God bless RBG
Love the verses
Where is your boat build?
I built my own kit with clutch and chain drive
Would you do an innengine?
How does the boat drive system work i have a 16ft john boat and needs a motor
I feel like people have been misled (myself included) by the stock Tillotsons 212 10 HP claim. The cam mic's the same as the Hisun 196.
What evidence do you have that the Tillotson 212 is not 10hp? Also, where do Tillotson claim 10hp? I can't see the claim on their website. Private sellers might make hp claims, but resellers are not Tillotson.
@@SportbikerNZ of the 6 karts and one mini bike I own. Having run (2x) Tillotsons and a number of Predators (hemi and non/stock-stage3), I can tell you for sure the ol butt gauge does not lie. And I should clarify. GPS claims 9+ HP on their inertia Dyno. It's not happening on a std Tilly 212. Can't wait till RBG pits it on his Dyno
@@SportbikerNZ what's your experience with them?
@@igokarts4510 Exactly - Tillotson has not made the horsepower claim. GPS has, based on their dyno.
Butt dyno doesn't really count.
I see GPS show some dyno vids on their channel. I doubt there is any reason to mistrust their figure.
@@SportbikerNZwhat's your experience with the Tillotsons?
Slm❤suka sangat bagus luarbiasa.
Muda mudahan aku dapat ini.
Was there any head porting or compression increase with this engine?
عالی پرفکت
عالی
It seems up to speed to me
Thumbs up for Hebrews 10:22!
That’s just insane. Someone traded a bass boat for a John boat they didn’t know what they had💀
just changed the size of the head ache by swapping down cheaper to fix and run a 212 verses a 150hp engine also
The torque peak is at a good afr but beyond that it’s absolutely too lean mate 100%
Build you a motor cover . Cut down on sound
hey, your HP means nothing. go learn about HP and TQ. Your max TQ is at 4500rpm. you need constant torque on a boat. Your engine is happiest at its max torque rpm, because that is the rpm where the engine is the most efficient.
You need to learn by watching the video. It's like you didn't even listen to him.
@@SportbikerNZ LMAO. By listening I commented earlier. perhaps you need continued education into
****reading comprehension skills*****?
why is braxton getting rid of the boat that doesnt make a lot of sense to me
and be sure the kid knows that boats are like cars and girls you never forget your first and will always regret
lastly the kid should know beforehand again like cars selling boat is a money losing deal
Bout dang time, we been waiting on another dyno video :|
