How do you plan on disabling it? When my engine (2002 90hp.) passed 12 years I decided to bypass mine. I undid the wires at the bayonet connectors; right side of engine where the blue/white stripe (as I recall, may not have had the strips and I think the PTT UP wires are lt. blue white stripe).
I then undid 3 screws (recalling from memory) and a hose to the pump and slid the pump out far enough to remove the drive gear which had a shaft attached....checking for thrust washers and none were present. Put the pump back and reconnected the hose and that was that. I wrote 1 pt. to 6 gallons of gas on the transom near the tank fill port so I wouldn't forget to add oil when refueling. Did I have to do it? No. Just slept better at night...one less thing to worry about. Did the engine care? No. I used WW Pennzoil Premium TC-W3 semi-syn which burned nice and clean anyway.
