"I have a 1977 wellcraft suncruiser 255 with a 351 windsor with mercruise out drive. I am having a power problem, boat will not run above 19 mph. When I am wide open the rpm's go to 3300-3400. should they be higher?
also what is the proper propellor for this set up. Distributor cap and wires are new as are plugs, What is recommended plug gapping. Any other helpful info as to what I should check will be greatly appreciated"
