I have a 96 75hp 3cyl merc #0g395022 the water stream coming out is steady and has a decent flow, the pee stream starts almost as soon as the engine starts, I have replaced the thermostat also and I dont know if its related to this but at an idle the motor seems to run rough as hell but allways starts and runs out as smooth as glass. Why would the water be this cold even after running for awhile. Thanks for any help.
