    I put the boat back in the water last week and while it is running a lot better and did get up on plane it maxed out at 20 mph. I’m thinking that it should do closer to 30 mph so I’m planning to replace coils, points, condensers and plug wires to eliminate the possibility that the spark plugs were the only ignition problem. Any suggestions on the best place to find the correct replacement parts for this motor? I see several options online but none correspond to the exact same part numbers listed in the parts catalogue for this motor.
