Was testing engine today on 1984 Starcraft Islander, Mercruiser 140 I/O. Ran engine in driveway with cooling muffs on for about 15 minutes. Did not put drive into gear at all.
and did not go over about 1500 RPMs.
Outdrive made slight noise while being (trim) raised for about 3 seconds. Then realized that I had not filled lower unit with 90 weight gear oil. Shut down. Filled with lube, ran again for a few minutes, raised outdrive... no sound this time. Everything seemed fine.... but I question whether I burned up the tapered roller bearings. Not sure how I would inspect these, or how I would know if they had failed.
Comments .....?
