Re: no power under load

First welcome to iboats. Is the bulb going flat? Check the tank vent. Or just soft? Check the fuel lines, could be pulling air. And I'm sure other ideas are to follow,,,,,

Re: no power under load

Will it pick up if you squeeze the primer bulb? If it does then you may have a weak fuel pump or missed something in a carb. The bulb will be kind of soft when running. If it gets sucked flat then make sure that your tank is vented. Don't know much at all about the 6 cylinders but these are basic points for all the outboards.
