Al Copeland watched while dogpaddling as his cat went up in flames. They didn't "engineer" the motor mounts properly and a broken housing allowed exhaust gas to blow-torch thru the bottom of the hull.

They're still loud, they're still fuel thirsty and they're still made for steady-state RPM operation. That's why in most large marine applications they're used in conjunction with diesels for maneuvering and low-speed operation. Solid, low-hour units are still very expensive.
The can mounts are what to use. Short for container.
They are what lycombing provides.
I assure you it is easier to rig then your piston counter part.
Pricing on two Turbines would be half the cost of two sterlings.
I am not refering to EBAY specials eithier.
How about two completely rebuilt with vibration analisys
and test cell sheets.

They are loud. I agree. But not really that louder then my
PSI 557,s were with 5 inch Stellings.

The bell housings crash boxes brakes are all available over the counter.
Exhaust gets a little custom its basicaly built for each application.

Beleave me I,m the biggest hack out there If I can do it
anyone can.

Have you seen the youtube video of the Turkey being thrown
through GE,s test Turbine.

Think about this it must pass and continue to run.
The next time your taking off in a plane watch out for
flying threw a flock of birds.

I've watched planes hit birds and fall from the sky- USAF.

Watched a T-38 on takeoff roll suck in a gull. Dropped like a rock. Since they were about to run out of runway, they tried to punch out- unsuccesfully. I was less than 1/2 mile away.

Turbines are wonderful devices but certainly not bulletproof or hassle-free.

what about the water cooled exhaust you see now. What affect does that have on the noise or anything? Warbird i believe was one of the first.

If I was to do it I would have one of the Marine Turbine Shops set it up the first time and I would just be doing the work from there on.

Yes I have a freshwater system. We are using distilled water also.

It is basically a onboard 40 gallon poly tank It has electric
zone valves feeding a water pump. This water outlet of the
pump is directed into a spray bar which feeds the intake
the water.

I have a few questions. First, what about insurance? Does Markel still cover you? Second, we float around alot just hanging out. If we get close to shore, I fire one motor and back away. How long is the start process? If you start them say, 6 times a day, will you smoke your batterys? Cheaper than blower motors? Thats interesting........
