    250 hpdi trim pushrods mushrooming?

    The ends of the trim pushrods on my 2007 250 hpdi are mushrooming. Yamaha tech at a tx said that I just need to file the edges of the deformation off to keep the rods the same diameter. Anyone had this problem, and if so, what do you use to file the pushrod, as I know a standard steel file will leave steel particles in the rod and rust.

    Thanks

    Sounds like repair under warranty. Does it also effect full retraction of the rods? Mine aren't like that.

    My 2006 250 hpdi has done this and my 2001 3.1 225 has done this as well. They should be replaced under warranty.

    Yup, had to grind mine off. Make sure you keep plenty of grease on them !

    The thing that makes me mad is that I have kept them greased, and after a year and a half, the rods are mushrooming, and the wear pads that the rods push against on the engine are nearly gone.
