I LOVE threads on OSO when I learn stuff !!!
Please keep this thread going......
Questions-
1. I think I read somewhere that John Aruda was working on a Bio-fuel source for his turbine applications, that would be cheaper and burn cleaner ?
2. What happens if the turbine gets wet?
3. How do you slow these things down ? Is there some kind of brake on the shaft ?
These are proably very dumb questions...sorry

Man I'm glad I asked the question! The only way I would turbine power a boat would be from someone who is reliable and knows how to make them work for a boat. The reason I asked about reliabilty is the guys over at the Aqua Toy Store said you always had to mess with them.The boat they have was one of Turbine Marines first installs.

We did a project for the military that had our T-53 down to 65db at 100 feet.. the technology is readily adaptable to marine use...

Don't know if John has worked on a Bio-fuel source for his engines or not but we were contacted by the government a while back about that verry issue and managed to prove that it was at least a viable concept.
Fresh water wet is no big deal... we wash them down all the time... even when running. Salt water wet you better have a good bit of corrosion protection on the magnesium parts cause if not it looks a whole lot like the movie ALIENS when the badguy's blood drips on the steel floor... lots of holes...
This is a bad thing especially when you consider that the powder residue is radioactive. (Inlet housings of T-53 engines are very slightly radioactive.) So salt water exposure requires a fresh water washdown.
yes there is a brake system on the driveshaft. you can see in the picture below the brake at the top of the drop box. This allows the engine to run at idle, but prevents it from spooling up to 3000rpm when in neutral and making it impossible to get back into gear. These engines are what is called FREE TURBINE engines and the power section is free to rotate or stop independantly of the compressor section. This means that you can stop the powershaft completely, and still have the engine running.

Hope this helps

Actions speak louder than gossip. Aquatoy store just bought two more turbine boats so they must be pretty happy with Turbine Marine.
In fact Turbine Marine has 9 NEW Turbine boats on order right now.
Everything we learn on the race course concerning usability and reliability goes into the customers boat.
