Hi Guys
Have a little issue with the Stbd Thermocon 350Q in my 1975 35' Aft Cabin. Last fall I was coming back on the Main River when my buddy behind me called on the Radio to tell that my Stbd. engine seemed to be smoking from the exhaust. After inspection found that it was steam coming from the exhaust. Much more than on the Portengine.(Outside air temperature was about 40F.) Water flow seemed to be a little less, but as indicated water temperature was running normal I continued and planned to replace my impeller after docking.
Next day I removed the impeller only to find it was still in good condition. I had replaced at the beginning of the season (5 months prior). I checked the raw water filter which was also OK. Now I was starting to runout of ideas. One of my buddies thought it might be a plugged riser or manifold.
So...Now I have a brand new exhaust manifold with risers and still have a steaming exhaust. What I have noticed is that when I start up the engine everything is normal until the Thermostat opens. Now comes the extra steam.... Running out of Ideas again....Need help. Headgasket maybe????
Lokking to hear your this,
