Why are these engines having so many problems with debris sticking in the thermostats. If I idle my 2007 opti 200 in anything shallower than 2 feet of water one of my t-stats sticks open and it will not get to operating temp. I took my thermostats out 7 times last year to remove small pieces of wood, weeds, or sand. Thats ridiculous!!! Last I checked this is an Outboard Engine... you know a motor designed to run in shallow water. Has this been a problem in all Merc outboards forever or just since the smartcraft guage came out to tattle tale the temperature. Anyone who doesnt have this guage doesnt even know they have stuck stats until their motor seizes.
