All good ideas, except the allen (drain screw) is recessed into the gearcase on Force motors. Later models have the regular flat head drain screw with a washer. The old design works fine except when it gets over tightened.
I’m sure you know the refill procedure, the ”fill” plug is on top next to the ”vent” plug. Or at least that’s how I remember it being. Fill it slowly to avoid air pockets. Quicksilver High Perf gear lube will give you extra protection in case of water intrusion.
I use Sierra 18 -2945 FIBER washers on Force motors. The nylon OMC ones won’t work. The Mercury 12-19183…3 BLUE coated washers will not work either on a Force. They will squash out when tightened, and will leak.
