This sailing season I've noticed a slight odor coming from my Universal M25XP on my 1988 E -32-200 when it has been running for a fair amount of time (45 minutes or more). Initially I thought it was coming from the breather hose but was not really concerned since it was a fairly faint odor. This weekend it became strong, to the point of almost overwhelming and there appeared to be a light haze (smoke) in the cabin. At first I thought I had cooked my alternator since the smell almost had an "electrical" odor but I'm still reading 13.7 volts output on the alternator. Today the odor smelled more like burning oil. The engine has been running at about 175 degrees at about 2200 RPM. I believe this is a normal temperature, correct? I pulled the engine cover when the engine was running and could not pinpoint the source of the smell. It's definitely coming from the engine someplace. I'm not losing oil as far as I can tell. Any suggestions on what this might be or things I could check?
