Just finially got the boat in the water after working on her for the last 9 months and the starboard engine is over heating and the port running a little warm. I have replaced both water pumps on the outdrives and they were pumping fine on the muffs and ran only a little warm on the starboard side and a little over the middle on the port side. I have read a little on this so the first thing I'm going to do is replace the closed coolant reserivor caps as they feel like their not seating tight. The next thing I'm going to do is check and make sure I haven't kinked the water inlet hoses when I reinstalled the outdrives. Then the thermostats and then the heat exchanger. Is there anything else I should be looking for? The coolant doesn't overrun into the reservoir as it would if the coolant was overheating. Starboard engine does seem to run a little rough when idling and smooths out a bit after it warms up.
