7.
Warm up a cold engine by running it at fast idle speed (as
recommended in engine manual) approximately one to two
minutes.
Leaving the Dock
After the engine has warmed up, you are ready to leave the dock. Before
you cast off, check all gauges, particularly the oil pressure gauge, for
proper readings. Check the operation of the steering by turning the
steering wheel to full port and to full starboard while observing outdrive
movement. Check that charging system is working properly. Check again
for fuel, oil, and exhaust leaks.
When you are sure your boat is ready, check wind, tide, current or other
forces that will affect the way you maneuver your boat away from the
dock. Then cast off mooring lines and stow fenders.
Shift your boat’s engine into forward or reverse depending on whether
you want to move the bow or the stern away from the dock first. Move
the throttle lever to neutral position. Then push forward quickly and
firmly to shift into forward gear or backward to shift to reverse. Your
engine should be running at a slow speed as you move away from the
dock. If you move the bow out first, watch that the swim platform does
not swing into the
Getting Up to Cruising Speed
After slowly motoring from the dock area to open water, you can safely
accelerate to cruising speed. Advance throttle to setting which provides
your desired engine speed (RPMs). As you move the throttle forward,
engine RPMs increase, and your boat moves faster through the water.
Important: Acceleration at full throttle is not recommended during the
engine “break ‐ in period.” This “break ‐ in period” coincides with the engine
“20 ‐ hour check ‐ up.” Do not attempt full throttle acceleration during the
first 20 hours of operation.
When you throttle up and accelerate, your boat increases the trim angle
and causes the boat to ride bow‐high. From a maximum angle, the boat
levels out to its planing attitude as you continue to accelerate. (Figure
5.2)
The maximum angle is commonly known as the “hump.” You should get
over the hump as quickly as possible because visibility, handling, and
performance are limited until you do. Only a few seconds at full throttle
should be needed; however, the way your boat is loaded, the wind, and
sea conditions affect the time required. When the boat gets over the
hump, it reaches its planing attitude. Then, accelerate until your boat
reaches a comfortable plane and then throttle down to cruising speed.
This also provides for better fuel efficiency.
When maneuvering at low speeds you can reverse (move throttle
forward or aft) the shift mechanism. This will react in a braking action.
CAUTION: When shifting between forward and reverse, always pause in
neutral for a few seconds before reversing the rotation of the propeller.
This will prevent unnecessary damage to the drive system
.
CAUTION
:
High speed acceleration in reverse can create a wake that
could wash over the transom and flood the boat.
