TRIM TAB DASH SWITCH

PORT ROCKER

STBD. ROCKER

Using trim tabs will compensate for uneven weight

distribution, listing, water conditions, wind velocity and

other factors that cause inefﬁ cient operation.

TRIM TAB

TRIM TABS

Trim tabs are installed on the

lower outside transom area.

Water is deﬂ ected and redirected

as the trim tabs are raised and

lowered from the dash switches.

This change in water ﬂ ow creates

upper pressure under the tabs,

and raises the stern. When the

stern rises, the bow is lowered.

Lowering the port tab will cause the port stern to rise,

making the starboard bow lower. Lowering the starboard

tab will cause the starboard stern to rise, making the port

bow lower.

Obtaining A Trimmed Position

Your boat reaches a planing position at a designated

speed. This speed is determined by bottom design, weight

distribution, water conditions, and on board equipment.

As the throttle is advanced the stern squats and the bow

rises initially. The trim tabs allow your boat to plane at a

slower speed than natural conditions allow.

In short bursts both trim tab rocker switches are pushed

simultaneously in the “bow down” position which causes

the trim tabs to move down. As the boat breaks over the

bow high attitude the boat speed accelerates and visibility

increases.

If the boat is over trimmed, it will plow the bow and

the boat will lose maneuverability. If this occurs, simply

short burst the “bow up” trim tab rocker switches

simultaneously.

In the “learning curve” process, press the tab switches

in half second bursts. You will notice a slight delay from

the time the switches are pushed until the boat reacts

depending on vessel speed. You will know after awhile the

optimum planing angle and speed.

When running in heavy seas press the “bow down” position

which will assist the vessel to cut through the waves. This

will produce a drier and more comfortable ride.
