Leaving the Dock
The procedure for leaving the dock is similar to the docking maneuver. If
the wind or current is pushing toward the dock:
• Cast off the stem line but keep the bow secure. Turn the engine to move
the stem away from the dock.
• Very slowly shift into forward at idle speed. When the stern moves away
from the dock, turn the engine away from the dock. Cast off bow line and
back away.
• When clear of the area, shift into forward and leave. If the wind or current
is pushing away from the dock:
• Cast off all lines.
• Drift off and when clear of the dock, shift to forward and leave.
TRIM/PROPELLER SELECTION
Trim
Boat trim while underway greatly affects boat performance and efficiency.
For best results, the boat should be on plane and trimmed to reduce the
wetted surface. With less boat in the water, both speed and fuel mileage
increases. Engines with manual trim must be adjusted for best overall
operation for the load and conditions. Engines with power trim should be
adjusted continuously for best results:
• Trim the engine in. As you speed up, your boat will increase its angle of
trim, causing the bow to rise. You can limit this effect by adjusting the
angle of the engine. The propeller needs to be trimmed in to force the
bow down and force the stern up at the start of a run.
☐ WARNING ☐
Keep one hand on the steering wheel and the other on
the throttle at all times. If the boat begins to operate
in an unsafe way pull back on the throttle and trim the
engine in at the same time.
• Increase speed. The bow will start to come down.
● NOTE ●
Do not trim the engine out too far or the boat may begin
to “porpoise” (bounce up and down). Porpoising lowers
top speed and fuel efficiency and also reduces control
and visibility.
