Hey guys, just picked up my first boat. 13' western with a 1981 johnson 9.9 and 1988 johnson 2.5. both motors run strong, the trailer is nice, and the boat is pretty clean. I replaced the impellor and spark plugs in the 9.9 but on my first trip out I think it started to overheat...smoke coming from the motor. I shut it off instantly and let it cool. Made it back to the dock and now I'm trying to figure out what the next step is. Thermostat? Can I flush the cooling passages some how? Any advice would be greatly apreciated.
