Re: Does hub HAVE to be replaced
Only factory Force props and Michigan Wheel props for that Force will fit. I'm aware of no others. It sounds like he's trying to sell you a universal fit prop that uses different hub kits for different brands. I'm afraid that's not an option for you. Force props use a smaller diameter spec where the prop fits inside the gearcase ring.
Force 48-FP685-1, or Michigan Wheel 071036 or 072128 assuming you need a 17 pitch. West's number for the last one is 192791. West's 19 is 203994 which is MW's 071037. My 2006 catalog shows $160 and it's probably a tad higher now.
