If you're seriously interested in this particular engine setup, make sure you test drive the boat throughly. You may want to test drive some others supercharged boats as well just to compare. Keep these things in mind when making a comparison; Throttle response, idle quality, blower noise and start-up when engine is cold. Keep in mind that this engine is fuel injected and if something isn't right, then you're going to need a professional tech to make "any" changes. Sometimes these guys are hard to come by when you need them the most.
