If you are handy with tools, there's always another route to take. There's a gentleman on here that goes by loudmouse. He uses a setup where he basically takes a 6.0 LS pullout, slaps two turbos on it along with the tune he's developed and goes. If he wears out the engine, no big deal; less than $2,...

L&LLandServices welcome to SA! :salute: If I am spending your money, it's hard to beat a Watherthunder engine! "We have devolved a complete line of LS1, LS2, LS6, L92 and LS7 all aluminum Small Block Chevy's starting from 400 horsepower all they way up to 900 horsepower. These Engines range from 34...

The power you can get from an LS is more than enough for a 14' boat. As far as hp/gear/prop, number one question is 'what are you going to do with the boat most of the time?' Sure, we all want that boat that will climb the Ridge fully loaded but is that practical for the couple times a year you need...

The software I use is called Diacom from Rinda Technologies. They have interfaces for almost every marine product out there (including PCM, Mercury, Marine Power, Seven Marine, and many others). Looking at their site, I see that the adapter used on Marine Power is the same used on PCM so the plugs ...

The software also allows you to do a number of different system tests, the most valuable of which is cylinder contribution test. You can also do test runs and record the results. This is useful because you can see trendlines developing; changes in oil pressure, fuel pressure, fuel consumption. In fa...

I can't say specifically for a Levitator but on the Marine Power version, the data port is at the front of the engine near the supercharger intake. It isn't an OBD II style plug; it's flat. You might look there.

I just wanted to give the folks at Buttraxx a shout out. I emailed them on Monday because I had one of my rain slips blow off. Shortly after the email, I was called and I explained what happened. The lady I spoke to (Mich?) said she had my order in front of her and clarified that it was the slip for...

I’m no engineer, but I don’t think this is practical for many reasons. A few are: 1) yes it will be quieter underwater, but the noise to power a tanker with air props will be unbearably loud above water; 2) you will lose reverse, which ships need; 3) it is probably a lot more expensive in fuel sinc...

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

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...

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...

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.

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...

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...

Does your analysis provide information on blade flex? If so, how closely do the analyses meet real world measurements? Just a dumb CE wondering out loud.

Oh boy. Here comes the pickle parade.

Looks like we're both going to be ready to hit the Swimming Hole soon! I'm thinking the day after your next boil at Mack's!

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? E...

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...

Sorry to hear. My condolences to all who knew him.

If you are running out in the grass in the Everglades, a flag is mandatory, regardless of what type of boat it is. From FWC: "No vessel shall be operated outside of Water Management District canals unless it is equipped with an orange rectangular flag at least 10 inches wide and 12 inches long and d...

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.

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 ...
