Yes, thats seal i ordered, it came in the seal kit. Seal kit;
Quicksilver 26-820645A1. At least thats what i was told.

the seal in the kit is just slightly bigger and doesn't fit. (How do i upload photos???)

Ive called around and searched all i could online. I come up with the same seal but its the same one i ordered. Im thinking of ordering it alone, maybe i got defective seal kit?? Im stuck.

its an older boat so thinking the lower gear housing may have been Changed, the number on the gear box is 435554-3, not sure if that helps or if i can order parts off that number.

That's more than likely a part # for the case.
Pic of the lower unit?

My entire holdup is that i cant find the correct seal. I ordered the one you mentioned and you can see from my photos that they’re diff sizes. So I'm stumped.

Looks identical to mine, but its a 88 force 50hp, if you go to boatnet.com the seal # for yours is F40307-2. Same as mine but im still waiting for mine to show up in the mail. Hope it helps.

Sorry didnt see the box with the same part# in your post. Disregard my post.

Just a heads up i got my seals finally and, seal f40307-2, the upper driveshaft seal fit perfect. Just in case your still checking in.
