4.6.2 Trim tabs

Trim tabs are available as an optional accessory. While the Yamaha engine power trim provides powerful vertical trimming capability, trim tabs provide additional control of the horizontal angle of the boat while under way.

Using trim tabs

Trim tabs provide additional heeling and horizontal tilting control. Situations where trim tabs are especially useful are:

  • When you need to trim the bow down in a rising sea.

  • When accelerating to cruising speed.

  • When running with a strong beam wind. 

The control options from the control unit are:

  • Port up/down

  • STB (starboard) up/down.

For more detailed instructions on how to use the trim tabs, read the manufacturer's manual. Read also the engine manufacturer’s instructions on adjusting the vertical angle.

Trim tabs can change the boat’s behaviour radically if not used correctly.

  • Adjust them carefully at high speeds.

  • Do not drive with the bow too low as this may cause the boat to turn unexpectedly.

  • The boat's two-stepped hull construction affects the boat's driving characteristics and the trim. Read more in section 6.3 Driving and navigating.

  • Trim tabs do not work at speeds below 10 kn.
