IMPORTANT: Note oil distribution hose routings before proceeding with disassembly.
Remove oil distribution hoses from the manifold.
Installation
Position oil tank assembly on powerhead. Clean mounting screws and apply Nut Lock to threads. Install screws and tighten to a torque of 30 to 42 in. lbs. (3.4 to 4.8 N·m).
Install protective sleeves and route oil distribution hoses from the oil distribution manifold to the crankcase oil delivery fittings. Refer to OIL SUPPLY DIAGRAMS on p. 157. Secure oil hoses to crankcase fittings with tie straps.

- Tie strap
Run outboard and check for leaks. Use Evinrude Diagnostics software to activate “Oil Prime.” Check oil flow through oil distribution hoses. Check oil system operation and routing of oil system hoses.
Repair any oil leaks and kinked or misrouted hoses. Install air silencer and engine covers.
Oil Injection Pump
Removal
Remove oil distribution hoses from oil manifold. Refer to Oil Distribution Hoses on p. 166.
Remove oil from oil tank.
Remove oil tank. Refer to Oil Tank Assembly on p. 166. Remove retaining screw(s) from oil pump assembly. Twist and pull up on oil pump to remove from tank. DO NOT pull up on oil manifold.

- Screw
Installation
Apply a drop of outboard lubricant to a new oil pump o-ring. Install o-ring on oil pump flange.

- O-ring
Install oil pump and manifold so that bend of oil pick up assembly is positioned to follow the contour of the oil tank as shown.

Install oil pump retainer screw(s). Tighten securely.
IMPORTANT: Turn self-tapping screws counter clock-wise to start the threads and clockwise to tighten. Failure to follow this procedure can damage the threads of the oil tank.
