U.S. COAST GUARD CAPACITY
Do not overpower or overload the boat. Most boats will carry a required capacity plate indi-
cating the maximum acceptable power and load as determined by the manufacturer follow-
ing certain federal guidelines. If in doubt, contact your dealer or the boat manufacturer.
WARNING
Using an outboard that exceeds the maximum horsepower limit of a boat can: 1.
cause loss of boat control 2. place too much weight at the transom, altering the de-
signed flotation characteristics of the boat or 3. cause the boat to break apart, par-
ticularly around the transom area. Overpowering a boat can result in serious injury,
death, or boat damage.
