Do not overpower or overload your boat. Most boats will carry a required
capacity plate indicating the maximum acceptable power and load as
determined by the manufacturer following certain federal guidelines. If in doubt,
contact your dealer or the boat manufacturer.

High‑Speed and High‑Performance Boat Operation
If your outboard is to be used on a high‑speed or high‑performance boat with
which you are unfamiliar, we recommend that you do not operate it at its high
speed capability without first requesting an initial orientation and familiarization
demonstration ride with your dealer or an operator experienced with your boat/
outboard combination. For additional information, obtain a copy of our
Hi

Performance Boat Operation
booklet from your dealer, distributor, or
Mercury Marine.
Propeller Selection
The propeller on your outboard is one of the most important components in the
propulsion system. An improper propeller choice can significantly affect the
performance of your boat and could result in damage to the outboard engine.
When choosing a propeller, a full selection of aluminum and stainless steel
propellers specifically designed for your outboard are available through
Mercury Marine. To view the entire product offering and find the correct
propeller that is best suited for your application, visit
www.mercmarinepropellers.com or see your local authorized Mercury dealer.
SELECTING THE CORRECT PROPELLER
An accurate tachometer for measuring engine speed is important in choosing
the correct propeller.
Choose a propeller for your boating application that will allow the engine to
operate within the specified full throttle operating range. When operating the
boat at full throttle under normal load conditions, the engine RPM should be in
the upper half of the recommended full throttle RPM range. Refer to
Specifications
. If engine RPM is above that range, select a propeller of
increased pitch in order to reduce engine RPM. If engine RPM is below the
recommended range, select a propeller of reduced pitch to increase engine
RPM.
