FUEL SYSTEM PRIMING

Vent Line Clamp

Federal Regulations require that all outboards with a fuel vapor separator must be shipped with a vent line clamp installed. This clamp must be removed before priming the fuel system or starting the outboard for the first time.

Failure to remove the clamp may cause fuel starvation and poor running qualities.

Priming the Fuel System

Fuel vapors are highly flammable. Perform the following procedure in a well ventilated area. Extinguish all smoking materials and make certain no ignition sources are present.

REMOTE MODELS

Insert the fuel supply hose from the fuel tank into a suitable container. Squeeze the fuel primer bulb or activate the boat-mounted electric fuel primer until fuel flows from the fuel hose.

Once fuel flow is observed, connect fuel supply hose from fuel tank to hose fitting on outboard. Secure hose with Oetiker clamp.

TILLER MODELS

Connect the fuel hose connector to the quick connect fitting on the outboard.

ALL MODELS

Use the primer to fill the vapor separator.

The high-pressure fuel circuits and injectors will prime as the outboard is cranked with the starter. Observe all fuel lines, both in the boat and on the outboard. Repair any fuel leaks.

Failure to check for fuel leaks could allow a leak to go undetected, resulting in fire or explosion and may cause personal injury or property damage.
