A few seconds at full throttle should get the boat over
the hump and into its planing attitude.
After getting over the hump, accelerate until reaching
a comfortable plane, then throttle down to cruising
speed.Thisalsowillprovideforbetterfuelefciency.
T - 7 TRIMMING YOUR BOAT
A. Trim Tabs (Applicable Models Only)
Trim tabs are used to add lift to the boat’s stern, there-
by changing the boat’s attitude (see Figure T-2). This
lift can help the boat get on plane faster and remain
on plane at slower speeds than if no tabs were used.
Used independently, tabs can also correct listing
conditions caused by crosswinds, unbalanced load-
ing and quartering seas. Trimming your boat properly
involves two separate procedures, trimming or tilting
the lower unit and setting the trim tabs.
When you are sitting dead in the water, your drive
should be down and the trim tab switches are in the
BOW UP position. Accelerate until you get onto plane.
At this point your boat will be plowing through the wa-
ter with the bow down too far. Trim the lower unit up
slightly until the bow comes up. If you trim the lower
Once you have spent enough time practicing maneu-
vers and have a feel for how the boat handles, you will
be ready to run in open waters.
T - 6 ACCELERATION
Before accelerating to bring you boat on
plane, be sure that the area in front of your
boat is clear. The bow will rise out of the water
momentarily before you plane and may tem-
porarily obstruct your vision.
If you have never had your boat on plane before,
chooseacalmdayforyourrstonplaneexperience.
Never boat beyond your ability and experience.
Before bringing your boat “on plane”, check the entire
area to make sure you have a clear, safe path. As
you throttle up to accelerate, your boat will increase
its angle of trim, causing the bow to ride high. From a
maximum angle, the boat will level out to its planing
attitude with continued acceleration. This maximum
angle is known as the “hump”. Because visibility, han-
dling, and performance are reduced, it is advisable to
get “over the hump” as soon as possible.
