85hp force carburetor float replacement

[Thomasp454]

First post but have used this forum for about 10years when working on my 1987 VIP with an 85hp Force. I recently had the tab break off the float of my top carburetor. I have a friend that said he could "fix it" and long story short is I need a new float. However this is a discontinued part both the Mercury F10135 and the Serria 18-7205, and I'm having issues finding a replacement. I plan on calling a couple of local marinas tomorrow and pray they have one, if not does anyone know of an alternative float that would work?
