I have a 200hp 4 stroke. I was running it on muffs today. Muffs on lower unit plus a hose to the flush port. The water coming out of he tell tale was hot. I just replaced the theromostates. The temp gauge was indicating just lift of the center line. I ldont recall it being hot before. Is this normal? I dropped the lower unit and checked the water pump it looked ok. Any ideas.
