Re: New to Iboats and boating
The good news is that it is basically a Mercury outboard motor.
I don't know what parts are unique to that drive train though as there were not many models with that setup. Mercury had a boat with that setup. I know nothing about the jet unit...that could be universal (?).
Other manufacturers made similar boats but with different setups. This is where you're going to get bit - having to to the dealer for parts. Hopefully you don't run into NLA parts. Once you get it together though, it'll be a cool ride.

Don't get discouraged (yet).
