I'm trying to bring a 1989 Merc back to life. I rebuilt the carb and tuned the motor up. Crazymanme2's advise fixed my starter problem (bad solenoid), thank you. Now the problem is no speed. Motor starts fine and runs good, but there is no speed. I know I'm pushing a bigger boat (1648 Seark) but would think I would get a little more speed. On today trip boat would not even plain out. I would estimate speed at around 10 to 15 mph on todays trip. At full throttle it seams there should be more in the tank, doesnt seam or sound like motor is wound up all the way. Is there something I can do?
