    I had a similar Mercury 4 with that problem. New parts, where available, cost a fortune, like $400. Used parts or assemblies were hard to find.

    It’s all needle bearings. The needles will be bad, and whatever surface they touch will also be bad. I was happy to sell mine a s a "parts motor".

    Long live Johnson and Evinrude, they got the job done with simple and inexpensive sleeve bearings. Why a sub 10hp engine needed a jeweled lower unit is beyond me.
