I need to replace the circulating pump on my engine, I plan to do it while the boat is in the water, anyone see any problem?
 
Closed Cooling System.... or Open System?
If closed, you can use the automotive short body version, and save a few dollars.... the circ pump will not know that it's been installed on a marine engine.
However, if "open", you'll want the Marine version.

Thank you very much for the quick response, I didn't think it would be a problem, being above the water line and no pressure.
Thanks - Good Forum
 
For future refference, best to post in the Merc forum. Not all the Merc guys frequent the other engine forums. Although there is a Volvo guy that does!! LOL
