Hello Guys, I am in need of some assistance from the experienced crew here.
I have a mercury optimax 115hp, serial 1B255833, with a Vengeance 48-16988 SS prop.
I have a lower unit rattle when I put my outboard in gear at idle while running on muffs, the clank, clank noise is much more prominent in reverse than forward. Noise goes completely away when the prop is removed. I have not had a chance to go test the motor in the water this season.
I was told it may be prop chatter (I must say this noise was never present in the last 15 years I have owned the motors) and was recommended to upgrade my prop hub kit as I still have the original from 2006. My problem is that while searching part numbers, some diagrams shows the newer hub Flo-Torq SSR 8M0150151 and other diagrams show 835257K1. I believe the 835257K1 is the same one I have right now, but want to know what you recommend, or what you think the noise may be.
Thank you in advance.
