I'm looking at getting a new jetboat, and I have to make the choice regarding the fuel delivery system. The base motor is a 350 carbed model. For another $1000, you get a throttle body and for an additional $400, you get a PFI. Now what should I do? I love the electronic fuel injection concept, but is it worth spending this $$$$. Also does a PFI engine have an injector at each cylinder? BTW - I'd love to have a boat with a Cummins - but the boat would be way to big for my applications, in both size and price.
