When you need to disable the oil injection system on your outboard completely, you must disconnect the electrical service and the appropriate oil lines, taking care not to create a spill. Because the oil reservoir and the oil injection system provide the correct amount of oil for your motor, mixed with gasoline, and because your motor would suffer a catastrophic internal failure of all systems within the powerhead without this oil, be certain to re-enable the oil injection system before operating the motor.
Items you will need
Standard slotted screwdriver
Clean oil collection receptacle
Unscrew and remove the starboard lower engine cover with a standard slotted screwdriver. Pull the sending unit 3-pin wiring connector out of the retainer and unplug the connector from the engine harness. Remove the screw holding the top of the oil reservoir tank in place.
Compress the clamp tangs of the metallic spring-type clamp that secures the the fuel filter outlet hose, using pliers. Slide the clamp back onto the fuel hose, past the fitting. Place a small drain pan beneath the hose and filter, then push the fuel hose from the filter fitting.
Remove the screw holding the bottom of the oil tank and the mixing unit brackets to the powerhead. Pull the bracket away from the powerhead if necessary to gain access to the mixing unit. Cut the wire tie that secures the fuel hose to the mixing unit outlet nipple with a pair of wire cutters.
Place the drain pan beneath the hose and the nipple. Push the hose off the nipple. Plug the hose with a golf tee, or insert the hose into an clean oil collection receptacle. If you opt for the golf tee, wrap the tee with duct tape to prevent it from falling from the line.
