To save someone the hassle I'll post this. Maybe I searched the wrong way but I found very little about this online...though the part number comes up now that I have it, but not at Mercury. I could not find it in new catalogs online but I know it was in old ones, no doubt are dropping the Force stuff. Maybe I'm so used to finding things online I got paranoid, lol.
My old Force 85 has a SS prop but a newer style not the old solid hub type. It has a plastic flare that plugs the prop end to make a diffuser (that flare out at end of prop barrel)....prop has no diffuser. Then the washer and nut goes behind that. It is mounted: thrust washer/prop/plastic diffuser/washer/nut. The prop has the old Merc inline spline (IIRC 15?) but prop is shorter the Merc hardly fits. Prop is open inside as for exhaust, but this is the single exhaust one piece force LU not the later dual exhaust. This is not the old Chrysler style cone that covers the nut behind a solid hub prop. My prop is actually a SS Michigan Wheel. Look up the part # to see photos.
My prop nut came off and I lost it, luckily I had it in gear to shore and prop stayed on. If your Force ever starts to torque steer a little and wants to cavitate more than normal when trimmed up....be careful. Feel free to replace that old nut since these have no nut lock tabs.
Here are the parts:
Quicksilver F532299 Spacer - is the diffuser/cone/whatever you call it
Quicksilver 12-F1866 Washer - goes behind the nut. IIRC just a locking 5/8 brass nut is used and you can get those easily for other outboards.
It was cheaper at my local prop shop once we figured out what it was, was less than $30 for both with tax. I looked at a few online and many were more with shipping to me.
