Re: NEW boat build- weighing my options

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,...

Re: NEW boat build- weighing my options

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...

Re: Diagnostic port on 6.2

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).

Re: Diagnostic port on 6.2

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...

Re: Diagnostic port on 6.2

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.

Re: Powering oil tanker with airprops (is it possible)?

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...

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.

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...

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...

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 ...
