Hello from Kennewick wa, first time post. my 88 OMC the zink inside the prop shaft cavity is about 50% gone. I am finding in order to replace it I must split the drive. The drive is fine and I would rather not split it. I will be sailing down the columbia to Ilwaco and leaving my boat in brakish/salt water for a few months for off shore salmon/tuna season. Any one know of a easy fix? could I just bolt a zink to the fin? Thanks for any help Byron
