Possibly in my box of bits in my garage! What one do you need? the trim tab on the bottom of the leg or the one across the bottom of the clamp bracket?
I have a set of barely used ones from my now departed 55BE, however I think the trim tab one fits a sizeable proportion of the Yams, It's unscathed & still in it's box. The clamp one may only fit 50-90(ish) Hp, and is slightly corroded (not unrelated to the demise of the engine, but that's another story.....). If you can wait 'till tonight I'll get the part number for you.
