Adjusting trim angle

EWM02471

WARNING

●Make sure that all people are clear of the outboard motor when adjusting the trim angle. Body parts can be crushed be- tween the outboard motor and the clamp bracket when the outboard motor is trimmed or tilted.

●Use caution when trying a trim angle for the first time. Increase speed gradually and watch for any signs of instability or control problems. Improper trim angle can cause loss of control.

●If the outboard motor is equipped with a power trim and tilt switch located on the bottom cowling, use the switch only when the boat is at a complete stop with the engine off. Do not adjust the trim an- gle with this switch while the boat is moving.

Adjust the outboard motor trim angle using the power trim and tilt switch.

1. Power trim and tilt switch

To raise the bow (trim-out), push the “” (up) side of the switch.

To lower the bow (trim-in), push the “” (down) side of the switch.

Make test runs with the outboard motor set at different trim angles to find the position that works best for your boat and operating condi- tions.

Adjusting boat trim

When the boat is on plane, a bow-up attitude results in less drag, greater stability and effi- ciency. This is generally when the keel line of the boat is up about 3 to 5 degrees. With the bow up, the boat may have a greater tendency to steer to one side or the other. Compensate for this as you steer. When the bow of the boat is down, it is easier to accelerate from a standing start onto plane.

Bow Up

Too much trim-out puts the bow of the boat too high in the water. Performance and economy are decreased because the hull of the boat is pushing the water and there is more air drag. Excessive trim-out can also cause the propeller to ventilate, which reduces performance further, and the boat may “porpoise” (hop in the water), which could throw the operator and passengers overboard.
