Johnson 9.9 prop question

[Island-life]

Hello

I recently purchased a new prop for my 75 9.9 10r75c. New prop is a Solas Amita tri blade part # 2111-093-10
I made sure to cross reference the model number and it appears correct however the issue I'm having is not enough space to insert the cotter pin. It seems as though the prop is slightly longer than the original prop. I made sure the prop was fully seated but can't squeeze anymore out of it. Has anyone encountered this before? Or does anyone know of a remedy? Any help would be greatly appreciated.

I apologize I might have posted this question in the wrong ​​​​​section :facepalm:

Is the thrust washer on the right way.

Thanks for the reply,
Yes it is. The smaller end of the washer seats into the prop as it should. Maybe it's possible to get a thinner castle prop nut or maybe even a thinner prop spacer? I'm really at a loss

Update: looks like my issue is the thrust washer is a tight fit when seating into the new prop to the point where its not seating right down. I could probably tap it in with a rubber mallet but is the thrust washer suppose to be able to slide within the prop? Or is it okay if it's a snug fit?

After further investigation it looks like this prop requires a solas specific thrust washer! Case closed

No it doesnt, I have 2 of those props and use the factory thrust washer on my 77,79 and 85 motors.

Thanks for the reply,

Oh seriously? Well not sure what's going on then.. When I looked at the solas made thrust washer it had a slightly different design compared to what I have and read somewhere some guys who bought a solas prop ran into a similar issue so I assumed that must be the issue because this thrust washer doesn't want to fit properly. Do you have a picture of what your thrust washer looks like? Perhaps the one on my motor right now is incorrect. I have only had the motor 2 seasons and haven't had to do anything to the prop

I will take a pic of one of my washers tomorrow. I just bought my second solas 2 weeks ago for my 1985 15 hp and it fit right on. I would call solas about that because it should work It may just be the paint is too thick there. I use 2 of those props on 3 different motors with 3 different thrust washers.

Sounds good thanks for doing that!
Hmm yeah maybe too much paint inside the housing I'll give solas a call tomorrow and see what they say about it.
