Get with Painterchic. Tonya is a master. And, yes, the vinyl does very well on rudders. Hulls too.

Re: pro charged a/c boats

On a boat that size I have to say you are setting yourself up for a world of heartache. Can it be done? Sure. Will it last? Doubtful. And, you will spend a fortune in avgas keeping that beast fed. Keep in mind that with a supercharged air-cooled engine you have to throw a bunch of fuel at it to keep...

Re: Tsi0540

I am by no means an expert on aircraft engines but I am a pilot and have some knowledge that might be useful. Yes, the lower compression pistons are to accommodate boost from the turbochargers and help prevent detonation. However, most, if not all, turbocharged aircraft engines are set up as what is...

Gauge Package

Finally putting my Thurman together. My instrument cluster allows three gauges. One is going to be voltage, one for oil pressure but not sure what to do with the third spot. Oil temp or cylinder head temp? What would you recommend? Also, for oi pressure, electric or capillary tube? It's a SV 540.

Re: Greetings from minnesota

I'm a Ford guy from way back but sometimes you have to go with the flow and in the airboat world, it's either aircraft or Chevy by a wide margin. That being said, if you must go with the 302, you can ditch the marine manifolds for headers; you won't need a water-jacketed exhaust. Also, what Gator sa...

Re: New AirRanger Set up ?

Owning a heavy DB with the LSA, I think I can weigh in here. First, you are leaving lots of power on the table by choking that engine down to 4,900 RPM. Whether that engine is a Levitator or Marine Power setup, it can safely turn 5,600 - 5,700 RPM. I'm running a 2.55 gearbox with a 4 blade 81" NGR a...

Here's a question that I've thought about for a while and can't seem to find a solid answer anywhere. The fact that pretty much all of us live in Florida and a large portion lives in South Florida, is there any real reason to run a multi-vis oil? Wouldn't it make better sense to run a straight 30?

Re: bulldozer prop.

So you say you can get 750 @ 5500 We will use that as a constant. At 2.0 that gives a theoretical mechanical advantage twice the input making 1500 At 2.55 that 750 leveraged by ratio can yield a theoretical 1912 When you get to building serious efficient engines and try to add in another 75hp the c...

You might consider the Excalibur. 72" 4 blade bowtie. Great push and good top end as well. They wok very well in direct drive applications. Just so happens I have one for sale.

Re: 6.0 Powerstroke in a river jetboat???

To some degree, I would echo what Seven3 said. The biggest flaw in the 6.0 design is the head bolts. When International designed the engine, they used a minimal amount of head bolts. To make matters worse, they used what's called Torque-to-Yield bolts. Millions of engines of all sizes have used TTY ...

Re: Need Help Selling an Airboat

Nice looking boat. My guess is two-fold; first, it's a bowhunting setup so you have a very limited market from the get-go. Second, like any other high cost 'toy', the initial depreciation is very dramatic. Given those two facts, if you need to get it gone, you're going to have to lower your price. A...

Re: Performance Unlimited

Mast is a good choice but put your money down and buy a Waterthunder. You won't go wrong. The engines are built from the crank up to be used in an airboat. Dave has put tens of thousands of hours into his designs and they work. If I had it to do over, I would have gone that route.
