Installation Information

Boat Horsepower Capacity

Exceeding the boat's maximum horsepower rating can cause serious injury or death. Overpowering the boat can affect boat
control and flotation characteristics or break the transom. Do not install an engine that exceeds the boat's maximum power
rating.
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.

Start in Gear Protection

Starting the engine with the drive in gear can cause serious injury or death. Never operate a boat that does not have a
neutral‑safety‑protection device.
The remote control connected to the outboard must be equipped with a start in neutral only protection device. This prevents the
engine from starting in gear.

Selecting Accessories for Your Outboard

Genuine Mercury Precision or Quicksilver Accessories have been specifically designed and tested for your outboard. These
accessories are available from Mercury Marine dealers.
IMPORTANT: Check with your dealer before installing accessories. The misuse of approved accessories or the use of
nonapproved accessories can damage the product.
