FUNCTIONAL APPLICATION — REMOTE OIL TANK SYSTEM:
Per Yamaha and Offshore Marine: This pump fits into the side of the Yamaha remote oil tank and feeds oil from the remote tank to the outboard's main oil reservoir. It is the electric pump component of the Yamaha PrecisionBlend oil delivery system. When the main oil reservoir on the outboard runs low, this pump transfers oil from the larger remote tank (typically 2.8 gallons) through oil lines to the outboard. Failure of this pump causes the outboard's oil reservoir to run dry, triggering low-oil warnings and risking oil starvation if the warning is ignored.

SERVICE WHEN:
• Low Oil Warnings on Yamaha 2-Stroke Outboard
• Pump Not Operating (No Oil Transfer from Remote Tank)
• Burned-Out Pump Motor (12V Test Shows No Operation)
• Routine Inspection on High-Hour Yamaha 2-Strokes
• Remote Oil Tank Service / Cleaning
• Yamaha PrecisionBlend System Service

FITMENT NOTE:
This is an OEM-spec replacement Oil Feed/Transfer Pump for Yamaha 6E5-81900-01-00. ALWAYS verify the OEM part number from your Yamaha service manual or parts diagram before ordering. Per Offshore Marine: "Works with all Yamaha remote oil tanks" — but verify your specific application by OEM part number for exact fitment. Easy 12V test: apply direct 12V to the pump leads to confirm the existing pump is failed before ordering replacement.
