To adjust boat trim while underway:
1. Before accelerating, make sure both trim tabs
are fully raised.
2. Adjust the trim tabs to achieve a planing
attitude.
3. Use the drive trim to position the propeller
path parallel to the water flow.
4. Readjust the trim tabs to fine tune attitude.
Operate only one tab at a time and in small
increments. As the tab takes effect, you will
notice it causes the boat to veer off course
slightly. Correct for this as it happens.
5. To prevent the boat from listing, do not have
one tab further down than the other tab.
Improper use of the trim tabs at high
speeds can cause an accident or injury.
