I just fitted a new Rapture stainless steel prop to my Johnson 135hp motor and after 2 outings the bush has failed. The first outing was around 40 miles, almost all in deep water > 1000ft.. the failure happened only 4 miles into the 2nd trip and again in deep water. for the most part the trips were running at around 10mph trolling in deep water. I am 99% sure I did not hit the prop on the bottom putting the boat in or out of the water. Before I replace the bush just wanted to find out if anyone had any experience with such a fauilure.. could it be heat build up from exhaust gases during the low-speed trolling? <br /><br />Thanks...
