First of all, THANK YOU ALL for all the information
I see I do have a bit of homework now to make a decision...
Second, I apologize for opening what appears to be HUGE can o' worms here... ALLEZ!
But I do know I won't use rubber gaskets...
Third, I don't have photos to show of the project
, right now the O'Day is under two tarps, which are under 13" of snow... When I removed the pulpit, the holes and surrounding decking felt solid and there was no apparent leaking, but I think I will go ahead and ream and fill and redrill the holes just as a preemptive measure. and for the FUN of it!!
When the weather
improves, I'll attempt to take photos for posting
