1996 75HP is a different system. The cover bolts apply to a three ram 2-stage system used on 85-150HP. Yours is probably a leaking ram. If it was anything else then you should have found it by now.
Not too familiar with your setup but my guess would be that the SS pin is galvanized into the aluminum swivel. It seems unlikely that ss shaft to ss piston eye would sieze. The white powdery residue that looks like some kind of salt or lime deposit is actually corroded aluminum. It laughs at your normal rust penetrating oils. There is an aluminum lubricant that also softens ALOX when it can reach it. Vinegar makes some difference. Heat is usually the best thing. Aluminum, ALOX, and stainless will expand and contract at different rates which causes the ALOX to crack. Once it cracks you can often begin to wiggle it free.
I think I have a 70-75HP ram if yours is cracked. It might just be the top seals though. If it turns out to be more than seals or if merc. won't sell you the seals that you need then pm me.
