The last couple of times out on the lake, I noticed a sharp hammering or clunking sound when letting off the throttle to settle off plane. It can be felt through the hull, and occurs 2 or 3 times when slowing down. Checked prop (25 P, T1) for tightness and clearance, and is okay.
I'm wondering if this is an indication of impending thrust washer failure. Any thoughts on this would be helpful.
