I am about to tear into this motor to replace the crankcase seal. I did a compression test on this motor and found I had a 10-15% difference between the 4 cylinders. Three of them were very close with 1 of the 4 making the 10-15% difference. From my understanding this is within specs but since I am tearing the power head apart does it make sense to rehone and replace the rings on this one piston? sorry I am new to this and this is my first outboard rebuild so I don't want do anything that will cause further damage.
Thanks in advance for you help
