That was a few years ago, and they don't seem to have been very popular. There's a bit more information (mainly negative and speculative) here: New Scorpion

How about Trimax?

These are prob the biggest makers of surface drives.

There was also an interesting looking drive fitted to a Pascoe at Ribex one year - can't remember the name - think they were Scandanavian origin. JK will know as I posted photos of them when he asked a while ago.

Even you should know that oil rigs don't plane very well.

Eco-drive I think. Brief mention here: Revenger 715

How about the Yellowfin VSD? I don't know when it's going to be on the market but they seems to have quite a few prototype installations. More here: Anyone Fitted Yellow Fin?

Ok i think my mind is made up on this one, jets are the way to go. The best jets "Hamilton" are made in NZ , easy for parts plus there local so thats what ill be using.

the problem i face then is getting over 50kts, hamilton say its pretty hard . pressmans ribs has a hamilton do you know what speed he gets (around 35-40)

Read a few past post about jets and Alan Pridy thinks they are crap in a big swell. I went out on a jet boat a week ago and it was blowing 40kts but here that means around 5m, geuss what? it was fine, whats he on about? have you experianced Jets going to pot in a side on swell? i have spoken with a few manufacturers that have installed hamiltons and they all seem very happy.

have you used both then coders? i have not seen many ribs with Rolls Royce jets. hamilton seem well used in NZ's commercial relm, i have to say i am not an expert on jets so all comments are taken into consideration.

madmat do you run on surface drives?

Jhon i am right in thinking the yellow fin never got off the ground, am i not?

thanks
