I have an an 83 OMC. I put it in the water a couple of weeks ago and just parked it in my slip at marina. It is about 2 miles from the boat launch to the marina. After getting underway i thought i may have heard a squeal a couple of times like a pully sliping or something. Went ahead and and docked it then last Sunday boat fired up ok went out and went bout a mile and a half and heard the noise again backed off the throttle and the motor just cutoff. When i tried to started it iwouldnt hardley turn over. Ichecked the oil before I puti it in the water and it showed full, I know it was not level on the trailer when i checked it but thought that was ok. I checked it when it stopped and it wouldn't even show on the dipstick. I never heard any loud braking sounds from the motor or drive but I did get a whiff of gear oil when it quick. I read onhear somewhere that you can pull the drive away from the motor a little and see if the motor turns over. I have a Seloc manual i hope that it is in their on how to do this. I guess my question is do you think Im lucky enough that it could just be the bearing on the shaft to the motor from the drive?
