"I have a problem with my 1987
"I have a problem with my 1987 272 Formula. I have excessive steam coming from my port side mercruiser 350. Here is the background.
alpha one outdrives, new impeller, new engine circulating pump, new exhaust manifolds and risers, new thermostat, boat is in a slip 4 months a year. The boat was used in a freshwater lake until I bought it 5 years ago. I installed perko flush kits immediately and use them everytime I go back to the dock. The engines are raw water cooled. I changed the plugs and none of them had any rust on them. The engine runs great except when idling down to the bay, i have to watch the temperature because sometimes it climbs way above 155, sometimes to almost 200. I immediately put the drive in neutrel and rev the engine and the temp drops down again. The temperature only rises at low idle. It is fine when cruising. But there is the constant steam coming from the silent thunder exhaust. (Basically a through hull exhaust.) Any ideas of help would be appreciated."
