ing the engine “break-in period.” This “break-in period” coin-
cides 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 throt-
tle forward or aft) the shift mechanism. This will react in a
braking action.
Steering Your Boat
Watch the stern when you turn! Steering a boat can be compared
to driving a car on slippery or icy pavement. Be cautious always.
When you turn the wheel, the stern responds first by swinging out in
the opposite direction of the bow. When you are trying to avoid an
object in the water, this swing could turn out to be critical.
Always give yourself plenty of room to make a turn. You also should
slow the speed of your boat while turning. Never make sharp, fast
turns as this could cause loss of control. Remember that your pas-
sengers should be seated whenever you’re underway.
Trimming Your Boat
Trim refers to the way a boat floats on the water. Your boat will work best
when it is trimmed to run at an angle between 3 to 5 degrees to the
water. You can trim your boat by shifting gear or passengers or, if your
boat is so equipped, by adjusting the drive unit angle or the trim tabs.
Power Trim
The operator can adjust his craft to the ideal boat angle for load and
water conditions by trimming the drive unit (Figure 5.3). The power

CAUTION:
Never trim drive unit up and out using TRAILER
switch while boat is underway. Use extreme caution when oper-
ating with drive unit raised. Severe damage to drive unit may
result if unit is raised beyond the gimbal ring support flanges at
engine speeds above 1200 RPM.
