Tried to replace our zinc with a camp P4 sent to us and had a difficult time getting the cotter pin through the lock nut and shaft. I have been told we need a P3 and also a P5. Our hull# is 277 and I have been told many different sizes. we also had to replace both lock nuts. Any suggestions of the correct size. Calgon

We have Hull #232 and use Camp P5 ...no problems.

Thanks for your reply. Our dealer sent us Camp P3-4 and insists that is correct. We had tried the P4 whisch was not a good fit. It seems like we get different info from every direction on this.
