Hi Everyone,

I'm new to this game, bought a Scat Hovercraft (wreck)last year, I have been doing it up since. I had it running for a short while then the engine packed in. Discovered the crank seal and bearings were worn. Took the crank to SEP at Kegworth nearly 4 months ago, they say the conrods are worn and need replacing but can't get hold of any.

Does anyone know where I can get hold of a good crank and/or conrods for a Cuyuna 430? if not I'm looking at replacing the engine with a Rotax 447 which with a gearbox retails at over 2 grand.

I came to a few race meetings last season and really enjoyed it, I was hoping to get this heap restored and race next season,

Any advice or help is greatly appreciated, thanks.

Cheers Stu (Notts). http://hovercraft.org.uk/images/icons/smiley_icons/icon_redface.gif
