I will add a plug this season while TD is on the hard. I still have only 23 hours on my 3 year old Moyer rebuilt. Mostly back and forth from launch / haul and maneuvering in close harbors. We can sail onto and off of our mooring. It is time to replace the oil because of its age if nothing else.
Just out of curiosity how much did that rebuild cost?
Did you take it out and put it in yourself?
