Default Turbinator Turbine Powered Catamaran

Eventually got started again on the turbine cat after many setbacks.
If all goes to plan and I pull my finger out she should be ready for the water this year.
I created a little web site to document the build.

I was wondering when we would get to see this.

Nice and clean installation.

I see your containment blanket


How did you know what height to install the drive?

oh It was already rigged prior?

Hot shaft engine is much more boater friendly

Fuel tanks have been moved down into the sponsons to keep the CG as low as possible.

I spoke with Rik at Arnesons about mounting the drive, I have managed to get the prop level and just below the spray rails.

I wish I had started with a better hull but choice was limited at the time I started the build, there is one thing for sure she is light the whole package is around 3 ton.

What size water pickup are you going to use?
I used one inch and had so much water pressure it blew
the double clamped hose right off and began to sink the boat
at 140mph.


I ended up adding a 1- 1/4 dump with check valve right out of
the strainer.

Another note I never really have had to use the manual
circulation pumps.
Even in long no wake zones the oil temp would be below
190 degrees.

I have been thinking about this, so far I have rigged it with a 1.25" hose double clamped. I went with a large circulation pump originally because I was going to water cool the exhaust.

I decided to keep it simple for a first project and ditched the water cooled exhaust due to the work needed to pull this off.

Looks like I will have to fit a pressure dump to the stariner to keep the hoses in place.
Not sure if I will be running at speeds of 140+ but we will have to see how stable she is when in the water. I am little concerned about the torque steer on a single engine setup.
But there is only one way to find out!

Not having water cooled exhaust can be dangerous. What are your plans to minimize the danger of fire?

Aluminum boat and a short stack should do it along with fireproof insulation on the lower section of the exhaust.
