    Clunking Noise at idle.


    06 f12 with 100 hours. I am hearing a distinct clunking noise when sitting idle outside the water. Here is the video:

    any idea? I can hear it at idle on the lake as well.

    Pull pump and grease drive shaft splines with grease or anti sieze and noise will stop, inspect water stator for the stainless liner swelling and hitting your impeller

    Ok, thanks. I'll have to read up on how to pull. I took some pics of the impeller and clearance. Looks like it's not hitting the walls.
