1985 Bayliner 1950 Capri - OMC 5.0L Stringer Drive - Shift Issues(?)
The last three times I have taken my boat out, I have noticed intermittent "thump" in sterndrive when going from standstill to plane. It does not happen every time but when it does, it goes like the following:
Last month the boat was at shop and the stern drive fluid levels were all checked and good. The engine was tuned up and runs well. I checked the fluid in the lower unit today and it’s still full.
I know very little about stringer stern drives and not sure if this is a shift cable adjustment issue or something more nefarious, like issues with the internals of the stern drive. Stern drive had major work on it two years ago to tune of about $3000. My father owned the boat at the time so not sure exactly what was done, he mentioned the seals where done and I assume the water pump but not sure what else.
I have an appt in late January with boat shop and not sure if it’s still safe to take out for light duty fishing in bay until that time or if its best not to risk causing damage. I was also hoping to get some feedback on what the possible issues might be so that I am more aware going into the appt.
Thank you!
Mike
The last three times I have taken my boat out, I have noticed intermittent "thump" in sterndrive when going from standstill to plane. It does not happen every time but when it does, it goes like the following:
- Boat Idling at ~500 rpm in neutral
- Push throttle into forward position, hear the sound of boat going into drive ( slight ratcheting sound of gears engaging I assume, plus a very slight thump when it goes into gear)
- Boat starts to move forward
- When RPMs get to about 1200 or a little higher, I hear/fell a brief single thump
- Boat continues on plane and no other sounds or vibrations noticed
