Default Jet Engine Powered Boat

I'm thinking of installing a small jet engine in a model boat. Either in a Rigger or an actual Unlimited scale boat. Thrust powered? Gearbox to a prop? Anyone have any experience / ideas / thoughts?[:-]

At the powerboat meeting in Heilbronn there was a guy (Thomas Hasenbein, I believe) who had adapted a Graupner helicopter turbine jet engine for his (monohull) boat, geared down to a surface piercing prop.
The boat ran very nice, not spectacular fast, but the flames from the exhausts sure were!

If I can find a link/pic/info, I'll post it.

Regards, Jan.

LOL!! They actually haven't released pricing but the $99,999 tag on the site might just scare a few!

WOW! That must be an error. Who would buy that for that kind of cash?????? I'm looking into $2K to $3K for a small jet and play with that.

Yep, that's the one I meant.

Here's another manufacturer:

Looks familiar?

If you really want to look at putting a turbine into a boat take a look at MHZ. They have finished their final testing of their turbine motor which drives a gearbox and runs to a prop, so no thrust is needed just a turbo prop. I cant paste the direct link for the boat so follow these instructions for the pics.

Go to MHZ's webiste [link]http://www.mhz-engines.com/[/link]

Then click on the top flag, german color.
Then click on "Galerie" blue tab
Then click on the "Action" light blue tab
THen finally click on "Turbinen Boot MHZ" tab

You can go to the american version of the site but its lacking some things, the boat that they placed it in I think is the muscle firewater shockwave which is 96.9" long.

If I remember the specs on the whole setup, the turbine spins at the above mentioned 118,000 RPM and is hooked directly into a gearbox that steps it down to around 21,500. When all is said and done, the torque is comparable to a Zen 260, but with more horses available. If I remember right, this thing burns(literally)70cc's of fuel(kerosene or diesel if memory serves)at idle per minute and 200cc's at WOT. And the $99,999 is a figure that IS on the website while the system is under development

There has been a scale Donald Campbell K7 world record attempt jet boat running in north east UK in 2004. Pure jet thrust, dont any more details, been some coverage in UK magazines. Maybe somebody can let us know more about it .
