Zephyr prop washer

[George Emmanuel]

There is supposed to be a washer under the tension spring for the Zephyr’s slip clutch. The question is, “Is it a metal washer or fiber washer”? There was no washer on this motor and it shows in the parts book. The only reason I’m asking is because of the copper plating on the spring and possible incompatibility with a stainless washer.

Since no responses, I’ll say what I did. I have some phenolic rod, so I machined a washer for the Zephyr. It is both strong and non-corrosive. Should do the trick.

Not that I know Zip about Zyphers,but, I did own two at one time and strange as it seems I may
know something you may not,
The two Zyphers had differences in
the way prop shaft area. Probably due to an evolving design. I pointed this out to the fellow who
took them off my hands.
Interesting motors, but, outside of my area of interest,
Good Luck

Here’s a parts diagram for the 1949 model. This was a 1 year and done model for the last year of the Zephyr. I view the gearcase as the predecessor of the “weedless” gearcases on the 1952-1967 OMC 3 Hp motors. Quite different from the earlier Zephyr gearcase.

Sorry for the late update…..we’ve been out of town for a while.

The above diagram is for the later model. My grandson’s has the earlier slip clutch type prop. I machined the phenolic washer and it worked great! That allows the prop nut to create extra tension on the cone spring and the phenolic prevents contact between dissimilar metals. His motor runs great!
