Yamaha prop on mec

[Deep6er]

Hi I recently bought a used Yamaha prop for a spare for my 115 mercury. The splines fit but it doesn’t seem to be long enough to put the nut on

Different hubs I beleive and different thrust washers

Yeah, looks like you need a much thicker thrust washer

Get the yamaha thrust washer and you have to trim a piece off. My buddy has done it on a 150 but that might be a little different.

Yamaha uses a really thick splined washer. Followed by a flat washer.

Would love to know if there is a prop cross-compatibility chart/website/etc.

I've wanted to play around with prop size/pitch on my e-tec, but have no idea what's involved in changing hubs, thrust washers, spline count, etc.
