Outboard motor installation

• Overpowering a boat could cause severe instability. Do not mount an outboard motor with
more horsepower than the maximum rating on the capacity plate of the boat. If the boat
does not have a capacity plate, consult the boat manufacturer.
• Improper mounting of the outboard motor could result in hazardous conditions, such as
poor handling, loss of control, or fire hazards. Consult your dealer or have a Yamaha-
trained person experienced in proper rigging mount the outboard motor.
Too much weight on the transom could change the center of gravity, buoyancy, operating
balance, or performance of the boat, which could cause loss of control or swamping. Con-
sult the boat manufacturer for the maximum engine weight allowable on the transom, which
is different from the overall boat capacity. Overloading the transom with an outboard motor
that is too heavy could also damage the hull, transom, deck, or helm area, as well as the out-
board motor and other equipment.
