Thread: Anyone built a mini jetboat? 3m?

You could literally stockpile a couple at that money/availability. I know of several that are super and/or turbo charged in sports cars and go like the hammers of hell.

I have a k24 turbo on ethanol in a 3.8m.It is a little more complicated than you make out but k24 is a good choice but depends on what you want in a boat.A $500 dollar motor is a drop in the bucket in the overall build price.
