I have a barely used 1997 Wellcraft Excel 21S. Bought with 16 hours on it and went to drive it home and blew the head gasket. Didn't know the thermostat was stuck and there she blew..In need of one a.s.a.p. If another motor is available, i.e. 305, 350 and so on, that you know are compatable w/ Volvo/Bravo One then please let me know. Very non-knowlegeable on swapping or interchanging..Let me know if I can put a different one in or if you have an avenue for a longblock.. ophillys@verizon.net Chris
