Smoke on the Water
my yanmar single started smoking out of the harbour a few weeks ago, out of the exhaust through hull ( raw water cooled). Was down a bit of oil so topped up; ran a few more times, shorter runs but no problem, checked the oil, then again the other night it started smoking down in the engine comp.... almost had a battery smell to it ..
there are no obvious leaks on the manifold, or block, oil level seems ok....
could I be cooking the batteries? What about the smioke out of the exhaust ???
It has given me no trouble in the last three years exept when I blew an impellor, and sort of overheated it once two years ago...
there is a squeeking noise coming from down below, I ad attributed to the stuffing box which is not dripping as it should, but doesn't seem to get hot ? and ther is a small amount of filings in the trans case oil, which is over filled.
I have noticed a bit of oil dripping on the bottom of the block area, but it's always been there....
Any suggestions as to where to start would be appreciated.
