Thanks, John. I had the mast pulled yesterday and I'm heading to the yard to take a look. According to Thumper at Pacific Seacraft, the mast step on the PSC 34 is attached with lag bolts. I really hope it is, as I don't feel like messing around with the headliner.Do a search for "Splitting Compression Post" and there is more information there.
Or maybe this link will work: https://www.sailnet.com/forums/pacific-seacraft/249913-splitting-compression-post.html
I posted a pic of the new cast aluminum mast plug from LeFiell that I installed.
Our 1980 C37 just had a hole in the step and plug--no stand pipe or drain holes and rot had started in base of the post.
The new step had both and fixed the water intrusion problem. West epoxy thinned with MEK fixed the soft wood.
Bottom line: all the bolts to remove the cast mast plug and SS step can be removed but it's a chore.
