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.

WARNING
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.
Fuel System
AVOIDING FUEL FLOW RESTRICTION
IMPORTANT: Adding components to the fuel supply system (filters, valves,
fittings, etc.) may restrict the fuel flow. This may cause engine stalling at low
speed, and/or a lean fuel condition at high RPM that could cause engine
damage.
ELECTRIC FUEL PUMP
The fuel pressure must not exceed 28 kPa (4 psi). If necessary, install a
pressure regulator.
LOW PERMEATION FUEL HOSE REQUIREMENT
Required for outboards manufactured for sale, sold, or offered for sale in the
United States.
The Environmental Protection Agency (EPA) requires that any outboard
manufactured after January 1, 2009, must use low permeation fuel hose
for the primary fuel hose connecting the fuel tank to the outboard.
Low permeation hose is USCG Type B1‑15 or Type A1‑15, defined as not
exceeding 15/gm²/24 h with CE 10 fuel at 23 °C as specified in SAE J
1527 ‑ marine fuel hose.
