Rectifying A List; Using Stern Drive Power Trim With Trim Tabs; Porpoising - Regal 3760 Owner's Manual

When trimmed or in the bow down position, the bow spray
is farther forward, the wake and rooster tail are smaller,
and positioned further behind the vessel. Also, when
trimmed you will notice that the tachometers show an
increase in rpm's.

Rectifying A List

Your vessel can use the trim tabs to
rectify a list. The trim tabs adjust the
boat's attitude in the direction the
helm rocker switch is pushed.
If the port bow is high, push the left-
hand "bow down" direction on the
dash rocker and the port bow will
lower. If the starboard bow is high,
push the right-hand "bow down"
direction and the starboard bow is
lowered.

Using Stern Drive Power Trim With Trim Tabs

the trim tab system is that they allow the trimming of the
hull while the power trim results in trimming the props.
Porpoising is a running condition where the bow "bounces"
up and down similar to a porpoise motion. Press "bow
down" in one-half second bursts. As the trim tabs turn,
the porpoising should recede and the vessel speed should
increase. Only a small amount of "bow down" is normally
necessary to make this change.
Adjust the trim
tabs to achieve a
planing attitude.
Use the power trim
to position the prop
path parallel to the
water flow. At this
point the trim tabs
may need a fine
adjustment.
