Trim tabs
NOTICE
Ensure continuous visibility of other boats,
swimmers and obstacles during bow-up
transition to planing. Adjust engine to an
intermediate trim as soon as boat is on plane
to avoid possible ejection due to boat spinout.
Do not attempt to turn boat when the engine is
trimmed extremely down/under/in.
The 230 Dauntless is equipped with electrically
powered trim tabs.
The trim tabs are located on the lower section of
your transom and are used to trim the list of your
boat caused by uneven weight distribution, too
many persons on one side of the boat, or strong
cross winds.
An untrimmed boat will:
• Decrease operator visibility
• Reduce fuel economy
• Increase wear on your engine.
While accelerating there is some loss of forward
visibility before the boat is on plane, the trim tabs
can be used to adjust for forward visibility while
underway.

Operation

The trim tabs are controlled by rocker switches
located on the center part of your console above
the throttle control. Short momentary bursts of the
rockers will achieve proper attitude of the hull.
The trim tab switch is marked "bow up" and "bow
down".
Using the trim tabs will:
• Level the boat fore and aft.
• Reduce resistance in the steering system.
• Give you a smoother more stable ride.
• Speed will increase and there will be less strain
on the engines.

Maintenance

The trim tabs are a completely sealed unit and are
waterproof and maintenance free. Aside from a
general cleaning when the boat is out of the water
you should also inspect the planes and hinges for
marine growth; remove as neccessary.
