ing speeds to make minor adjustments in the fore and
aft and beam-to-beam angle of the boat.
To use the trim tabs:
1. Place the "house" battery bank master disconnect
switch in the "ON" position.
2. Switch the Main - One circuit breaker on the Safety
Breaker Panel "ON".
3. On the DC Control Center, switch the System DC
Main circuit breaker "ON", then switch the Trim
Tabs circuit breaker "ON".
4. The trim tabs controls are located at the helm. The
controls consist of two switches. The port switch
controls the port tab; the starboard switch controls
the starboard tab. Each switch is labeled "BOW
UP" and "BOW DOWN." Before advancing the
throttles, press both switches on the "BOW UP"
side for 5 seconds. This lifts the trim tabs to the full
"up" position.
5. Advance the throttles to bring the boat on plane.
Adjust the engine RPMs for cruising speed.
Do not overtrim your boat. When adjusting the trim
tabs, press their control switches for only one-half
second at a time, then allow the boat to respond.
Continue to adjust the trim tabs in this manner until
the boat is at the desired trim angle. Over-trimming
can cause the bow to veer and may lead to loss of
control. Always reset the trim tabs to the BOW UP
position before advancing throttles to achieve plane.
Accelerating the boat to planing speed while the trim
tabs are lowered can cause a loss of control.
6. Use the trim tabs individually to make beam-to-
beam adjustments. If the majority of your passen-
gers are sitting on the port side, you may find that
the starboard side of your boat is riding higher than
the port side. Use the "BOW DOWN" side of the
starboard trim tab switch to adjust the trim.
