Reply To: OMC-1956 30 hp motors -thrust washer on prop shaft question

[Bob Wight]

My ’56 30hp Johnson did not have the thrust washer and the prop fit really loose on the prop shaft. If you look at the parts listing detail, the thrust washer was only used on the RD-18C which also shows a different prop, prop drive pin and prop nut than the original RD-18 or RD-18E. So I assume the RD-18C was some type of revision during the production year that modified the original design. The original model/serial ID tag on my motor was missing so I didn’t know what model it was, but when I cleaned and resealed the gearcase, I ordered a thrust washer off Ebay, put it on and the prop seemed to fit properly.
