"I picked-up a neglected 1985
"I picked-up a neglected 1985 35 horse merc two years ago. Much time spent getting it to run reliably. Had to rebuild TnT pump housing, replace fuel pump, lines, carb float/seats, and remote controls. Purrs like a kitten now. I have read several posts with horror stories about separating the lower unit when replacing the water pump. I do not know if the pump has ever been replaced and am wondering, should I attempt to take it apart now and possibly ruin a fine running motor, or wait till it begins to fail?"
