Hello. I have a 2006 Fishin Deck from Tracker, aluminum hull with a 115 outboard. The inside of the transom has a rubber seal to keep the water out at the seams and it is cracked on both sides. What’s the best product to repair? Do I need to try rip out the old seal or can I go over what’s already there? The old original product seems to be on there pretty good. Note, this is only on the inside of the transom. Photos for reference. Thanks.
