My cousin has a 1992 60 hp Johnson that will start, and run in neutral, but then stalls when they try to put it in gear. I sold her the boat almost two years ago so I'm tryin to help. The motor went into the shop for carb rebuilds and water pump repacement in April. When I picked up the boat, the mechanic told me he was really happy with how well it was running. They put the boat in the water last weekend and discovered the problem. Does anyone have ideas before I bring this back to the mechanic?
