I have been out of boating for quite a few years and during the interim I have taken up Porsche 928’s as a hobby. For a brief period, Porsche dabbled in marine versions of their 928 based water-cooled V8’s. I have one of these marine conversion kits and want to build a jet boat around it. I’m sure I can get much more bang for the buck with American iron but the novelty of running the 928 engine is what this project is all about.
So now my questions to you, the experts:
In stock form, I have only 300HP @6500 RPM. Do I have any chance at all of reaching 70 MPH with a jet?
What type of hull will give me the best performance?
Anybody have any good candidates for sale? Glasswork and paint are no problem. I would prefer something without an engine but with a good pump setup in place.
Any and all help or advice is appreciated.
