Regal 3550 - Trim

Systems
THE BOAT TRIM SHOULD BE ADJUSTED TO
PROVIDE BALANCED STEERING AS SOON
AS POSSIBLE EACH TIME YOU GET
UNDERWAY. SOME BOAT, ENGINE AND
PROPELLER COMBINATIONS MAY CREATE
BOAT INSTABILITY AND/ OR HIGH STEERING
TORQUE WHEN OPERATED AT OR NEAR THE
LIMITS OF THE “BOW UP” OR “BOW DOWN”
POSITIONS. BOAT STABILITY AND STEERING
TORQUE CAN ALSO VARY DUE TO
CHANGING WATER CONDITIONS. IF YOU
EXPERIENCE BOAT INSTABILITY AND/OR
HIGH STEERING TORQUE, CONTACT
YOUR AUTHORIZED REGAL DEALER
CAUTION
!
DO NOT RUN ENGINE ABOVE 1000 RPM
WITH THE STERN DRIVE TRIMMED FOR
SHALLOW WATER MANUVERING SINCE THE
STERN DRIVE IS OUT BEYOND THE GIMBAL
RING SIDE SUPPORT BRACKETS.
OPERATING IN ABOVE MANNER COULD
PRODUCE A DANGEROUS STEERING
CONDITION OR COULD DAMAGE
STERN DRIVE COMPONENTS.
CAUTION
!
OPERATION IN “BOW DOWN”
POSITION
The “Bow Down” or in position is
normally used for acceleration onto a
plane, operating at slow planning
speeds, and running against a choppy
wave condition. It is also used when
pulling water skiers, tubers,
kneeboarders, etc. In this position the
boats bow will want to go deeper into
the water. If the boat is operated at high speed and/or
against high waves, the bow of the boat will plow into the
water.
OPERATION IN “LEVEL” POSITION
In normal running conditions,
distribute passengers and gear so boat
is level. At or below cruising speeds,
trim the vessel for optimum
performance. The trim gauge will
show somewhere in the center of the
gauge. This position will also enhance
running visibility and overall stability. Again, each outing
provides different wave, load and running conditions. Be
prepared to make trim changes as needed.

OPERATION IN “BOW UP” POSITION
The “bow up” or out position is
normally used for cruising, running
with a choppy wave condition, or
running at full speed. Excessive “bow
up” trim will cause propeller
ventilation resulting in propeller
slippage. Use caution when operating
in rough water or crossing another boat’s wake. Excessive
“bow up” trim may result in the boat’s bow rising rapidly,
creating a hazardous condition.
