OUTBOARD INSTALLATION

Important Information

BEFORE STARTING THE ENGINE

NOTICE

Lack of oil pressure in the system can cause severe internal

engine damage during start‑up. Prime the oil injection pump on

new or rebuilt engines or after performing maintenance 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.
