Rico,
1st, I want to commend you on the quality work and attention to detail you have bestowed upon Mephisto Cat! I am currently working in the lazarette / motor well area our our Commander, #256 and have a couple of questions for you:

1) Where did you find the replacement rubber seal that goas around the top edge of the fiberglass (aka: knife edge to some) opening? I have been searching for a seal similar in profile to Pearson's original, but no luck. Do you remember where specifically you obtained (source) and part number and / or description for the gasket you used?

2) Did you modify the original small drainage hole? The approximate 1 inch hole centered at the base of the forward motor well mount. Did you leave it well enough alone, enlarge it, or add any others?

Respectfully,
Chance
