HI Scotty,try adjusting the trim.if the boats out of the water,adjust the trim so that the cavitation plate is parallel with the bottom of the boat.use that as your start point,.try that for a start. |

Hi,the pitch of the prop may be too much.ive been suggesting PROPULSE props,where u can adjust the pitch to suit your power needs.Has it always been underpowered? |

Hi,theres about 2000 reasons why you could have dropped power.dirty carbs,linkages out of sync,electrical problems,fuel supply,motor getting tired,barnacles on the hull.I would book it in to a marine shop,and get it checked out |

You might have a stuck carb float which could be choking the motor at low speed. |

I just had mine worked on and it was 500 at the shop and the problem was the stator was bad. The motor would not idle but 1/2 to full throtle it went great. Try and look at yours. |
