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 passengers
should be seated whenever you’re underway.
Trimming Your Boat
Trim refers to the way a boat fl oats 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
trim system allows the operator to adjust the drive angle while
underway by changing the angle of the outdrive in relation to the boat’s
transom. It also allows the operator to raise and lower the drive for
trailering, beaching, launching, or operating in shallow water.
Note: Refer to your engine owner’s manual regarding the operation
of the power trim controls installed on your boat.
Drive Angle
The drive angle of the boat is the relationship between propeller thrust
to the planing surface of the hull’s bottom. You can improve the
performance of the same boat under varying conditions by adjusting the
drive angle.
Moving the drive unit angle towards its innermost adjustment brings the
propeller in as close as possible to the transom. The angle of the
propeller causes an upward thrust which pushes the boat’s bow
downward as shown on Figure 5.3.
