    How do you know that spark is going away when the throttle is applied?

    You are probably referring to a warm engine no-restart condition. That doesn't affect a running engine, only a re-start shortly after the engine has been shut down.

    The problem with your engine could be an RPM limiter condition, usually triggered by an overheat sensor signal (possibly faulty) or Low oil or Low fuel.

    The RPM limiter kicks in a specific RPM, and the engine power pulses on and off as the RPM rises and falls around the RPM limit.

    More likely is that the carbs are internally clogged, as that 2000 engine from the factory would have the gray Tempo brand fuel lines (as did many years). The gray lines are known to create a greenish goop that clogs up the internal carb filters.

    At a minimum, rebuild those carburetors and make sure they are 100% good. And replace ALL the fuel lines.

    The Ocean Pro 'O' ride plate is considered the best at reducing porpoising of the SL hulls.

    The "R' version of the Ocean Pro ride plate is also quite good, but the longer O version produces the smoothest ride in rough water.

    Smooth is a relative term. The SL hull has a fairly flat bottom, so it will always ride hard on 'big' water.
