Re: 26' Airboat

Anyone on here know the boats story?

I would think there has to be a story or two about something as unusual as this boat.

Kind of curious as to it performance too

Re: New AirBoat Owner

Full deck nice! That should be a good safe rig for a beginner.

Make sure you have multiple bilge pumps on independent float switches...my2cents

Re: Belt drive replacement belt

The BlackHawks were originally designed for high horsepower application where the standard materials would fail. If you don't have a high power engine say 500hp plus or use nitrous the standard belt should work just fine.

Sweet price on your find Coon very fair

Re: 7.3 diesel engine on airboat?

There were a few built at ridiculous cost back before the economy crashed. Then after things tanked they would pop up on eBay or craigslist for sale. You know when that happens it ain't good. Last one I saw for sale was somewhere up North like New Jersey being sold as is at auction. Maybe it was rep...

Re: Converting from car engine to aircraft.

If you had a 13ft boat and a 1.7 drive you would be very happy. Going to a 16ft and putting weight in it requires something upgraded if you plan to run any dry loaded. At a minimum to go on a drive you need to upgrade the timing set and get a shaft rocker system. Even doing that your at a bare minim...

Re: Converting from car engine to aircraft.

My experience was a 74 inch Q was the better Caddy length. Your L33 / 425 sounds strong for stock? Have you tried letting it idle for a "full minute" prior to shut down? What is the idle rpm? Factory spec was 500 rpm How do you have it timed? (Fatal error to push advance in a Caddy) Try adding in a ...

Re: Cadillac 500 - HOLY GRAIL

Later this week it will be at the Branch shop for a quick inspection. Then we will fog the cylinders with oil and put this baby into a cradle stand for storage. We will see where this one goes but I think it should stay together for now. It ran really good and the carburetor is desirable in GM facto...

Re: 76" NGQ RPM

You don't spin a 76 NGQ with winglets like you do some other shorter slick blade prop. Set it at 2750 on the trailer if you want to try a different setting and that should have you at 2850 on the water apx. We found the prop liked pitch and taking pitch out only favored a weak engine or an engine wi...

Re: re-power to a bigger motor

If your swapping to a V8 sbc and going "gear drive" the best power for the dollar is probably going to be a 383 crate motor. While not a purpose built engine the price and availability make it attractive to many. A lot of folks have had better than fair results using the Blue Print roller version. E...

Re: 76" NGQ RPM

It is hard to say if going up in rpm and down in your pitch will yield a gain in push. I would strive to put it at 2750 if it was me. I ran a 76 NGQ on a Branch 514 with Nitrous. We would choke it down around 2600 so when on the power adder we were under 2900 rpm. That prop liked pitch. If you set i...

Re: 350 DD boat

Looks good kid! I always run a spring (2 of them) on the carburetor. You don't want it pulling to hard fyi but stiff enough to ensure a sharp snap of the throttle.

Jordan if your just starting out the advice I would give is build yourself a real boat not a mini. A 12ft traditional hull is mini enough when you get to looking at it. There are a few low cost power options from a direct drive car motor, salvage LS carb conversion to using the new GM computer contr...

Re: Gheenoe Airboat

There have been countless attempts in the past 60 years to turn small boats into airboats. It never works very well. If you look up the old "Air-Boy" system you will see it was a commercially produced unit. Maybe look into a mud motor it would be more effective if the weight doesn't limit you. The l...
