should i keep quick slip or polly the boat Again, that all depends on what you use it for. If you don't plan on running much dry ground, slick bottom is fine. The more dry you run, the more often you will have to reapply the slick bottom, and slick bottom does nothing to protect you hull. If you pl...

Birddog247 on this site runs an old 350 that he pulled from a van, 2:1 gearbox, 2 blade R, on an aluminum hull, and I've yet to see him sruggle on the hill with 2-3 people. The belt box in question weighs more than his gear box, but the combo operates the same. Set-up would dictate how it performs, ...

500lbft/ 400hp turns way way less prop and makes way less thrust than 400lbft/500hp according to my AC pocket protected fuzzy math excel calculator the engines have equal power and both exceed waterthunder thrust expectations :salute: I challenge any CM calculators to prove me wrong!! :stirpot: :fi...

Need more info, how is it mounted? Electric fuel pumps are designed to push fuel, not draw it from the tank. The closer to the tank you can mount it the better. Does the tank have a pickup tube that draws from the top, or is the outlet mounted low (gravity fed). I run a Carter on one boat (car motor...

Looks like a great little boat, should serve your purpose well. If your future plans are just riding with your wife, it may be all the boat you'll ever need. Would be a nice frogging boat also.

I said the same thing to him Greg, if Kyle's boat got stuck going to the treehouse, mine might as well stay on the trailer (lol)

I had the same issue with a Blueprint 383 we purchased (used). The #7 piston had a broken ring land when we tore it apart. I replaced the piston, but honed all 8 cylinders and installed all new rings and bearings (crank and rods), reassembled, set the timing at 34 degrees total, and it's been runnin...

Like Rick's, mine is on the side of the case just below the base of #2 & #4 cylinders (IO-0470-L). A little tough to see and get to.

What prop is on it now? If it was a 350ci, I would suggest a 70" Q prop, and keep the rigging light and it would run the hill ok. Being a 305ci, I would venture to say a gear reduction of 2:1 and a 78" - 80" 2 blade would be needed at a minimum for it to perform anywhere near what you...

Different strokes for different folks as they say. I understand a lot of folks don't have the means/ability/room to build and work on their own boats, but in my case, I take a lot of pride in the fact that I build most of my own stuff, from my airboats to my trucks and cars. I make a pretty decent l...

call me CM curious at this point SG keep your man-card punched! don’t be drinkin that CM kool-aide, that’s all smoke n mirrors, high rev low torque blah blah, never see those guys deep in the sheet where the real AC guys hang, they’re all the time gettin towed in, rebuildin their junk, spewin ani-f...

Great video Kyle, glad to be a part of this again, looking forward to Earth Day next year!

670 Holley Street Avenger on my Son's direct drive, no issues at all, turns a 70 Q 2900rpms all day long.

We run a "Cadillac batwing" style cleaner on my Son's small block. Should he get caught in the rain, he can just spin the air cleaner 180 degrees so the intake duct faces the back. Not the best setup, but works fine.

As far as who to call? My suggestion is to join one (or more) of the many airboating clubs in Florida. Post on here when and where you are riding, to see if any others may be riding that particular day. Another good source is Southern Airboat Facebook page if you do the Facebook thing. Always better...

Glad it's working out to your expectations, lot of time and money but looks like it was worth the effort!

[quote="Slidin Gator"]Finally, it looks like I have another book to read, I just ordered a copy of "Everglades Patrol".

I read it a few years ago, great read!

Sorry I couldn't make it this year (I made it the last 2 years), sometimes life (and work) gets in the way! Looks like ya'll had a great time. Looking forward to next year's get together!

Sounds like your initial disappointment turned 180 degrees! There was no doubt in my mind it would perform much better than your previous setup! Like mentioned previously, I think there's still some left on the table as far as the camshaft selection, but sounds like your pretty happy with the water ...

As far as BPE goes there are guys who get by running them but more have problems as they are not built for the severe duty application an airboat exposes it to. My neighbor runs the same BPE383 so they will work if you take timing out and run blended fuel. Usually it is the Pistons or flat tappet c...

We found the same thing tearing down our Blueprint 383, broken ring land on #8, piston skirts were scuffed pretty bad, only difference was ours has Keith Black hypereutectic pistons. We were able to minimize the damage and got by replacing the 1 piston, and bead blasted the others, replaced the cran...
