Today I removed about 1/4 of a quart of oil
from my Yanmar
using the "oil extractor" I purchased from West Marine
- a very nice product. Once I removed this oil
, the level on the dipstick read about 3/4 of the distance between the "low" and "full" lines.
I went to start the engine
and right away on the first turn it started. No black smoke whatsoever.
I ran the engine
a little while giving it a little gas every now and then and the engine put out no more exhaust
than usual. I believe it may be fixed. After running the engine, I checked the oil level and it read 1/2 the distance between the "low" and "full" lines.
I will check it tomorrow morning again, but I think this was the issue and now it is resolved.
Thanks again to all who provided input/advice.
While doing this, I also noticed that my drive belt is a little loose. Now I know what next weekends project
