hi. I have a 1988 200hp suzuki. I'm having an overheat problem with only one side of my engine. I put a new water pump in. I also removed both thermostats. one side runs cold the other gets hot. I removed the thermostat cover of the side that is overheating and it runs cool, put the cover back on and it runs hot again. I removed the cylinder head to look inside and it looks pretty clean. Thats where im at now. Thanks!
