    Surge in Power

    My boat has about 14-16hrs on it and I have noticed when using the PP that as soon as I pull someone up and out of the water the boat slows down incredibly before throttling back up to where I have it set at. I read the PP manual and it mentioned something about a surge in power could be related to some throttle cable and to turn a black knob. I will wait on that till the 20hr service is ready. I can just pull without it for now. But.............

    This weekend out at Elsinore I had the boat full with 4 adults and 3 kids and even without the PP on the boat surged incredibly bad. I have ran the boat without PP so I know its not my driving and I have been in some chop already. Not to mention, the bilge came on by its self. I was taking in water and am not sure why. Would additional weight cause this? I should be able to sit that many people in the boat and not have a problem. Not to mention, what if I add ballast to this? Have anyone experienced this problem?

    the servo for the perfect pass kicks in @ about 1500 rpm (not sure about this number) if you keep the motor at this rpm the PP keeps kicking in and out and you'll feel the surge. just throttle through adn you shouldn't have a problem.

      I think your right. The PP works great once it gets up to speed. I am just wondering why the boat was varying in speed & RPM's even without the PP on. I tried to take it out this weekend without everyone weighing it down but I never got the chance.

        The surge you describe is normal. Once the engine gets to about 1500 rpm the PP kicks in. It's kind of awkward at first but you'll get used to it. I teach my drivers to smoothly accelerate the tach straight to 2800 rpm and wait for the beep, then retard the throtttle about 1 inch and let PP do the rest. More advanced drivers learn to anticipate the beep and back off the throttle right before the boat reaches the target speed, this minimizes 'hunting' during the first few seconds of the run.
