Hey guys hope you all are having a good holiday weekend, Yesterday was my first time out after flushing my coolant system, changing some hoses, getting my temp gauge in working order, also cleaned out my heat exchanger. 3.7 merc 165 with a closed loop cooling system. On muffs in the garage it never ran above 180 the whole time 30+ min. Now on the water I am running 190-210 ish with it being warmer at idle and slow rpms and temp reduces at high rpms. Coolant is full, no leaking from the engine. Outdrive water pump bad? my big thing is it never overheats per say, it stays right on the spot just runs hot. Also if the pump is bad can I change it without taking the outdrive off? I do align and grease gimbal every year so its all in check there, so if it is possible I don't see a need to pull it.
