I was only replacing because I was not sure how old the one on there was . I have owned boat for 4 years. Old one still looked good but I decided to change it and the gimble bearing as preventative maintenance.
My worry is a barnacle cutting through it with material being so thin,maybe I am paranoid...I am just hoping someone will chime in who has been using the new design without issues
I installed the new oem bellows #23075752. I have concerns about this new 'improved" style because it is very thin and rigid compared to older style rubber which was much thicker. Any insight on this I would like to hear.
