Outboard motor installation
• Overpowering a boat could cause severe instability. Do not install 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 a Yamaha trained per-
son experienced in proper rigging should mount the motor.
Too much weight on the transom can change the boat’s center of gravity, buoyancy, operat-
ing balance, or performance which could cause loss of control or swamping. Consult the
boat manufacturer for the maximum engine weight allowable on the transom, which is differ-
ent from the overall boat capacity. Overloading the transom with a motor that is too heavy
could also damage the hull, the transom, the deck, or the helm area, as well as the motor and
other equipment.
Consult the manufacturer of engine jack plates or brackets before mounting. Excessive
loads could damage the plates or brackets, the boat’s transom, steering system, or the
engine. This could cause loss of control.
