My 90hp force L drive is overheating at idle. Replaced water pump, hoses, heat sensor and power head but still overheats! Any ideas... Is this a chronic problem?
I would check to make sure you have sufficient waterflow through the engine. the thermostat is right on the head. there is a plastic screw thing on the head that goes to the thermostat. ive read that sometimes the lines and passages can get clogged. I have the same engine and i found my problem was a blown head gasket. couldnt tell till i took the head off. you can view my thread if you look under my name.
