I have a 2 cylinder 50hp Mercury. Which I've had some difficulty finding information on. I think it may be an OEM force motor.. Anyway I'd like to know what a "normal" output for water pump is. I'm assuming that it's out the exhaust because I can't find anything else that looks like a pee hole. I just bought this engine on a 24 foot Sun Tracker Party Barge that sat for 3 years. Finally got it running after some carb work and new gas but I'm concerned about the water pump.
