Thanks. I used the thrust washer that was on it with the original but thought it might be too thick since I wasn't able to thread the nut as far down as it was before
I have a black max 135 with Lazer2 that needed to be replaced. So I ordered a prop off eBay that I thought was identical. It's the same 21" pitch and mounts up but it's about 1/2" smaller diameter. Is the gap between the front of the prop and the gearcase housing ok. I thought about using it...
