Diesel acting up, ideas?
First, I am taking the boat to the local yard I trust since I have not touced the diesel on my own yet (18-month owner). Second it's a bit long winded I wanted to get it all in.
Engine is Universal M12 with Hurst transmission. Boat is ina river off the Neuse river/Pamlico. I assume we have fresh to brakish water. A month ago I ran the engine for ~30 min to clean it out and charge the batteries, al in the slip. No problem.
Last weekend was clean-up day and I was spraying mildew killer everywhere. I took one of he side panels off the engine compartment and sprayed the fiberglass underneath. I did not spray the engine directly but I'm sure it got enough incidental. Did not start the engine that day.
Next day, we take the boat out (left engine cover off). Engine coughs a bit but starts and runs fine. On the way out the channel the buddy helping me out is steering and I am putting things away, etc. Notice HOT smell, stick my head down companionway, smoke everywhere. I look at the gauges, temp off the scale. I put the engine in neutral (can't remember if I throttled down) and engine dies. I am unhappy. Furtunately wind is blowing into marina, so we float back top the end of the dock and tie up.
I notice the engine control panel (which is on the sidewall of the cockpit footwell, over the engine) is all steamed up. No smell of burning rubber or oil and I can actually touch the oil filter. After 15-20 min we turn on the ignition and temp down to bottom on gauge. So now I am thinking the water from yesterday steamed (steam, not white smoke) and faked out the temp gauge. We start the engine, watching the temp gauge and looking for smoke. Nothing. I crawl into the q-berth and I see a few white wisps, but now I am thinging it's steam.
We go out the channel, all OK. finally throttle down to put up the sail, look down: Temp off the scale; look below, smoke everywhere and now it's burning my throat (still coudl not identify it as burning oil or rubber).
By now we are outside and sails are up. So we sail around a bit to calm down. On the way back I sailed almost to the slip (involves a u-turn and backing in) started the enging to push boat back and turned it off pretty quickly, so never got a chance to heat up.
