Ok, I have my factory 225 Merc (1999) on my 27-foot Bayliner Trophy center console.

The engine is strong and generally reliable. I'm concerned about the water pump or thermostats. I have the water pump replaced every season and every season a good jet of water comes out the pee hole on the motor.

Only after a few hours it stops. Even when I plug the garden hose in the clean out port is stops coming out the hole when does so easily with the new water pump.

Motor never seems to get hot, over heat nor does the high temp alarm trip.

Did I miss something? Or is the motor just not getting warm enough for the termos to open?
