Re: Merc 3.7
That's great link and intro to the 3.7 that Ziggy posted! Check to see if you have the 4" heat exchanger and alternator conversion kit. If not, plan doing those ASAP ~ about $500 for the Sierra Alternator kit or $300 for the Breezeworks alternator conversion kit. The 4" heat exchanger I have been looking for used to save a few bucks but have not been able to find. A new one will run you about $550 - $650. I didn't do this yet and have been fighting high temp issues all season long!
Good luck with the boat!
