Filling the Oil Tanks

1. Remove the remote oil tank cap and fill the remote oil tank with the recommended oil. Install the cap and tighten securely.
2. The engine‑mounted oil reservoir may be filled by loosening the vent cap and using a squirt oil can to inject oil through the
vent cap finger retainer slot or, while the engine is idling, allowing crankcase pressure to fill the reservoir with oil from the
boat‑mounted oil reservoir. The engine‑mounted oil reservoir must contain at least 118 ml (4 oz) of oil prior to starting the
engine. The engine‑mounted oil reservoir must be monitored while the vent cap is loose and the engine is idling to prevent
leakage from overfilling. Tighten the vent cap securely when the reservoir is full.
IMPORTANT: The engine‑mounted oil tank must be completely filled prior to the initial operation. The boat‑mounted remote
oil tank will not displace the air in the engine‑mounted oil reservoir unless the vent cap is loosened.

Purging Air from the Engine Oil Reservoir and Remote Oil Hose

NOTE: Before starting the engine, verify the oil pump has been primed.
IMPORTANT: It is recommended that the engine‑mounted oil reservoir vent cap not be removed to fill the oil reservoir. Removal
of the vent cap may damage the threads in the reservoir. Damage to the threads may result in future oil leakage.
1. Loosen the vent cap on the engine‑mounted reservoir.
2. Start and run the engine until all the air has vented out of the reservoir and oil starts to flow out of the reservoir.
3. Tighten the vent cap securely.
