After getting over the hump, accelerate until reaching
a comfortable plane, then throttle down to cruising
speed. This also will provide for better fuel efficiency.

ACCELERATION
S - 7    TRIMMING YOUR BOAT
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 mo-
mentarily before you plane and may temporar-
ily obstruct your vision.
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 S2). 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.
If you have never had your boat on plane before,
choose a calm day for your first on plane experience.
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.
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
