Upgrade HP on 2003 GTX Super Charged 185
My friend at the marina wants to give me a 2003 gtx blown engine. When I rebuild/replace the powerplant, what is needed to upgrade the 185HP to perhaps 250? I am thinking about getting it this weekend and this type of craft runs well in the bay compared to the older 98 GTXL.

Major undertaking and $$$ to say the least, cast pistons, SC gearing, injectors, small tunnel, 155mm pump, 7650 rpm ECU, on and on and on.......

Find a used 255 engine and drop it in. You would need electrical components but other then that you should only have about 3K in it with little work.
