Just got the old 1967 Glastron back in the water last weekend after replacing floor and changing out motors. I now have two problems that I need assistance on. 1. My 76 Merc 65hp starts and runs but doesn't seem to run on all three cycinders until it after I run it awhile. Doesn't matter if motor is warm or cold.It finally kicks in and runs smooth and pushes the boat near 30mph. I must admit I didn't put new plugs in the motor and will try that next. It was also suggested that I Seafoam the gas to clean the carbs. 2. When motoring across the lake the boat tilts extremely to the right side.Yes this is where I sit but I only weigh 180 and If there are two of us sitting side by side it still tilts to the right. If I turn the boat to the left it then will level out. Is there an adjustment to the motor I must make to get her to level out moving forward. It does plane out front to back fine.
