Important Information
BEFORE STARTING THE ENGINE
!
CAUTION
Avoid engine damage. Prime the oil injection pump on new or rebuilt engines and after maintenance
is performed on the oiling system.
Refer to Priming the Oil Injection Pump for instructions.
FUEL REQUIREMENTS
Do not use pre-mixed gas and oil in this engine. The engine automatically receives extra oil during engine
break-in. Use a fresh supply of the recommended gasoline during engine break-in and after engine break-
in.
OIL RECOMMENDATION
Recommended Oil Mercury or Quicksilver Premium 2-Cycle TC-W3 Outboard Oil
IMPORTANT: Oil must be NMMA certified TC-W3 2-Cycle oil.
Mercury or Quicksilver Premium TC-W3 2-Cycle oil is recommended for this engine. For added protection
and lubrication, Mercury or Quicksilver Premium Plus TC-W3 2-Cycle oil is recommended. If Mercury or
Quicksilver outboard oil is not available, substitute another brand of 2-cycle outboard oil that is NMMA
Certified TC-W3. Severe engine damage may result from use of an inferior oil.
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.
Boat Horsepower Capacity
!
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 designed flotation characteristics of the
boat or 3) cause the boat to break apart particularly around the transom area. Overpowering a boat
can result in serious injury, death or boat damage.
