3.2.3 Got the attitude? About trimming your boat
Learn how to trim your boat in order to ensure a smooth cruise and optimal performance.
The trim, or attitude, of your boat is its running angle as it makes way in the water. Running in the wrong trim angle gives you a bumpy ride and loads the engine unnecessarily. Learn how to:
Adjust the boat’s vertical running angle (raise or lower the bow) when getting to planing speed or changing speeds.
Play with your trim until you find the most comfortable ride while cruising.
Adjust the boat’s heel (lateral angle) when travelling in a crosswind or with an unbalanced load.
You can trim your boat from the trim tabs control at the helm station. By using the trim tabs you can adjust:
The boat’s vertical running angle.
The boat's heel.
You can also trim your boat’s vertical angle using the engine throttle and shift control. Trimming changes the propeller shaft angle, which causes the bow to move up or down.
Poor trimming can risk lives! Adjusting the trim angle at high speeds may radically affect your boat’s behavior. A high running trim can obstruct the view so you may not notice swimmers and small vessels.
Avoid making adjustments at high speeds.
Don’t drive with the bow high for long periods of time. Trim the boat’s vertical angle to lower the attitude in congested areas.
See the trim tab manufacturer’s manual for detailed instructions on how to use the trim tabs.
