OS 25vf question
 

I know you guys will know the answer to this right away which is why I posted it here. I came to own a shrike and OS 25vf + pipe. The os engine looks like it has never been used but does not have a backplate or washer (not sure what the right name is) for the prop to back up against. The prop bolt is there but the other part that is on the engine side isn't there so theres nothing to tighten the prop up against. I assume this is because the engine is a fan engine. Is there a part that I can buy or do I have to make something up by hand.

Thanks.....looking forward to speeeeeed!

Thrust Washer ;)

I would try the OS web-site maybe they will list the dimensions and you can find a substitute- Also try a search on here for that engine...

Lastly, PM W8YE or Bob27, they are engine GURUS!

Cheers!
