I noticed when I bought my boat that the prop had 1/4 inch forward-backward, when I checked my friends boat his prop had a lot less play. During a fishing trip I hit a rock and had to replace my prop and hub kits. Once I was done installing the new hub and prop I noticed the play had been reduced to what my friends boat has, Thanks for the best sales service I have seem in years. The bad part is that the dealer said my old hub was working normal, thank iboats for correctly selling me the right parts. I highly recommend this site to all my friends and others wanting to buy boat parts.
