Installation Guide

1. Preparation: Ensure the engine is off and cool. Gather necessary tools including wrenches, oil drain pan, and a clean workspace.
2. Drain Engine Oil: Locate the engine oil drain plug and place a drain pan underneath. Remove the plug using the new oil plug drain gasket from the kit.
3. Replace Oil Filter: Remove the old oil filter using an appropriate filter wrench. Install the new oil filter, hand-tightening it according to manufacturer specifications.
4. Replace Fuel Filter: Locate the fuel filter on your engine. Disconnect fuel lines carefully and replace the old filter with the new fuel filter.
5. Drain Lower Unit: Position the outboard vertically and place a drain pan beneath the lower unit. Remove both the drain and vent plugs to allow old gear oil to drain completely.
6. Refill Lower Unit: Using the included gear oil pump, pump new gear oil into the lower drain hole until it flows from the top vent hole. Install new lower unit drain gaskets on both plugs before reinstalling.
7. Refill Engine Oil: Add the manufacturer-recommended quantity and grade of engine oil through the oil fill cap. Check the dipstick to confirm proper level.
8. Reinstall Drain Plug: Install the engine oil drain plug with the new oil plug drain gasket and torque to specification.
9. Prime Fuel System: After replacing the fuel filter, prime the fuel system by squeezing the primer bulb until firm to remove any air.
10. Check for Leaks: Start the engine and let it run for a few minutes. Inspect all filter connections, drain plugs, and lower unit plugs for any signs of leakage.
11. Final Inspection: Recheck oil levels after running the engine and top off if necessary. Ensure all components are properly secured.
12. Dispose Properly: Dispose of old oil, filters, and gaskets according to local environmental regulations.
