I had a brief love affair with a jet boat, years ago. I'm picking up a new hull and was thinking of installing a pump, Dom 12S. Set back? Why, just for more room in the boat or is there a performance gain? Is the plate and shoe going to do any good with a 500 hp +- power plant, or are they just for big motors. Would a loader be any better than the shoe? I would put a droop and diverter on it, is this where the plate would make more sense?  Thank you for your informative responses.
