Yamaha F90 squeaking

[Dlarson9393]

We have a 2010 Yamaha F 90 on our 19' Seahunt and we love the boat and motor. There are only about 25 hours on both engine and boat. There is a "squeaking" type sound when we are idling, we are still under warranty but if it an easy fix I'd rather do it myself. We had a Yamaha F 75 on a pontoon boat several years ago that did the same thing mostly after running at higher RPM's for a while. Any ideas on what this might be? Any help would be greatly appreciated.

Re: Yamaha F90 squeaking

Your motor may have a drive shaft bushing in the mid-section that needs some lubrication...
