Re: Coskpit floor leak on 86 PSC 37
Our 1986 PSC 37 also had a wheel and single piece cockpit floor. It was sealed with a thick layer of some sealant that was still flexible and sticky 20+ years later. We went to tiller steering so can't help re putting the wheel steering back in. We did, however, use the same 2" neoprene gasket material from McMaster Carr and it seems to be doing well.
good luck with the repair,
