Thrust Washer Qusetion

[FreeBeeTony]

Just picked-up my "new" outdrive.
​Put my thrust washer on and it seems to be rubbing against the zinc on the prop shaft.
The expert said it's OK.

Ayuh,.... The prop thrust hub should touch the prop shaft, 'n the prop,.... Nothin' else,....

I'm guessin' it's the wrong anode, or wrong thrust washer,.....

 

[FreeBeeTony]

Me too.
​Thanks Bondo.

Does P/N: 77987 sound right for the thrust washer?

Looks like Sierra has a replacement # 18-4220.

that would the the standard for all the merc drives using merc propellers. Some of the older michigan ones used a much thicker thrust hub

Found my original thrust washer deformed, see pics. What is the torque spec for the prop?

Bondo Found a new thrust washer.......only a few thousandths between the washer and zinc. sound right?
​Actually had a local marina give it to me for free...........imagine that! Still good people around even in NY.........was willing to pay..........he said "don't worry about it".
