OIL COMPONENT SERVICING
To prevent accidental starting while servicing, twist and remove spark plug leads.
Oil Distribution Hoses
The oil distribution hoses to each cylinder MUST be the same length. DO NOT alter the length of any hoses.
Oil Distribution Hose Length:
• 20 in. (508 mm)
Removal
Release the hose by depressing the outer ring of the hose retaining mechanism.
- Retainer mechanism 008067
Once hose is removed from the manifold, make sure hose support is in the end of the hose.
- Hose support 008070
Installation
Cut Replacement Oil Hose, P/N 778708, to the correct length. Insert hose support in manifold end of hose.
IMPORTANT: DO NOT insert distribution hoses into manifold without a hose support.
Be sure the hose is fully inserted into manifold. Insertion depth is 5/8 in. (16 mm). Visually inspect for hose supports.

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. (3.5 to 5 N·m).
Install protective sleeves and route oil distribution hoses from the oil distribution manifold to the crankcase oil delivery fittings. Refer to OIL SUP- PLY DIAGRAMS on p. 160. Secure oil hoses to crankcase fittings with tie straps.

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. 173.
Remove oil from oil tank.
Remove oil tank. Refer to Oil Tank Assembly on p. 173. 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.

Installation
Apply a drop of outboard lubricant to a new oil pump o ring. Install o ring on oil pump flange.
- O-ring 008064
2-CYLINDER MODELS
Install oil pump and manifold so that bend of oil pick up assembly is positioned to follow the con tour of the oil tank as shown.
008182
3-CYLINDER MODELS
Install oil pump and manifold straight into oil tank.
IMPORTANT: Be sure oil pick up assembly is positioned in front of oil tank baffle to prevent interference with the LOW OIL switch.
