I committed to buy a 2000 Chaparral 240 Signature. It has a Volvo Penta SX outdrive. Y pipe is present, complete engine was pulled and got seperated from boat. Came with 5.7GS Vortec. I need a used powerplant with all accessories to bolt on to existing outdrive. What can I or can't I use. Kids want to tube, I just want to be out on the water. I have a 4.3 Mercruiser 1988 that needs to be freshened up with Alpha outdrive, but don't think I want to swap that much original components. Go easy on me, my wife has already pointed out all my faults.
