Thanks to all for your suggestions.
I really didn't expect so much great advice. Appreciate all the response. I have the teak cover off for the winter as I am aware of the potential for compression post rot. (none so far) Where the boat is out of the water for the winter, i will try to tough it out and nake sure water doesn't build up and freeze. Pull the mast out after launch.Bigger problem was back siphoning of water into cylinders last year, leading to a seized engine. Am replacing with a 3YM30 and hope to find someone who can rebuild the old engine for resale. Block is fine, just a cylinder rebore.The joys of boat ownership are neverending.
