Re: Need Prop Advise for SBC 383

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 ...

Mitch Kline. Don't have his number but I'm sure somebody on here does. Better break out the wallet, though. He builds top notch hulls and charges for it accordingly.

Re: Fuel Pressure Issue

Something to check I run a aeromotive boost reference regulator and I've had to replace the diaphragm twice now in a year. Gets a pin hole in it and starts leaking fuel out the vacuum port. I'll have to check that. My regulator does have the boost reference port but I do not have it hooked up (I wa...

Fuel Pressure Issue

I have diagnostic software that allows me to monitor virtually any aspect of engine performance. I'm running an Aeromotive Eliminator fuel pump with an Aeromotive Bypass Regulator. When I originally installed the engine, and up to about 100 hours ago, I had 63 psi fuel pressure that would drop to ab...

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.

Re: 15x7 engine choice

I have a 15' DB that originally had the 8.1 Vortec on it, rated at 465 H.P. I managed to blow that engine and replaced it with an aluminum block LS engine. Made a huge difference in the way the boat rides. The 8.1 weighs 765 lbs, the engine I installed weighs approximately 500 lbs. Running dry is no...

Re: Does the dark side really have cookies????

Second on the 5.3. My buddy just recently put a 5.3 on a 14 ft Panther with stainless rigging. I think he paid about $700.00 for the engine, I gave him a cam I had out of my LSA, he bought a Holley FI system and bought headers from Norman Clay. All in he's got less than $3,500.00 into the engine and...

Re: Hull Taper

The older thurman hulls had heavy taper to drop the nose farther, those boats were built specifically to have a proper sized drawer on each side to haul a certain size package(s) that were extracted from certain areas back in the good ole boy days, wink wink. :lol: :lol: :lol: :lol: This guy.

Here's my setup. Triple in the back, side by side driver, double jump in front.

Re: Gearbox power reduction question

So what you're saying is you believe that a gear box has more parasitic losses than a transmission, at least 2 u-joints, a differential, axle bearings and tire/surface interface? Or are you saying 500 whp is more than 500 crank hp? If the latter, duh. Do you think so? [emoji12] Sent from my SM-G950U...

Re: Asking for opinions here

Here's a link to the article my buddy had. I was a bit off on the specs. The 5.3 with the LSA cam made 389 HP at 5,600 RPM, not 385 at 6,200. Pretty interesting article. Could give you some good ideas to work from.
