OK, I figured it out. The cap on the starboard side slide right off the trim rod with ease. The cap on the port side was a pain to slide off the trim rod. Since I started with the port side I was baffled by how the cap was supposed to come off. After I took the starboard side off and it came apart easily I understand how it works. As for the port side, I carefully positioned the trim rod upside down in my vice with proper wood/rubber contacts to prevent damage to trim rod and bottom. I then used a piece of wood to slowly knock the trim cap off by hitting downward on it from multiple sides. It took some pretty strong hits to eventually slide it off. Be extremely careful to avoid contact to the trim rod/cap assbly with any metal as it dings VERY easy. Once I got it all apart it was obvious how the trim seals could be replaced. If I hadn't had the snafu with the port side trim cap the entire job would have only taken 1 hr max. Instead I've got about 4 hr into it now
But at least I know how it all works now!
Thanks for the help. This is a great forum!
