Re: Repower from volvo engine?
Having a 34 year old Volvo engine in my Newport, all I can say is they are rock solid operating (though they may be a little noisy at times). I would get it repaired before I would shell out the $ to replace it. You can replace the motor mounts yourself, if you know which end of the wrench is up, and as far as the mixing elbow, mine was fabricated from black iron by a welding shop locally for about 1/4 the price of what Volvo wants for it.
Good luck, and good sailing...
