Evinrude 3hp shear pin size

[cajuncook1]

Can anyone give me the shear pin/ drive pin size dimensions for a 1966 Evinrude 3hp? Im away from my PC so I don’t have my notes and manuals.

Appreciate your help in advance.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

If you know any welders, see if they have any 1/8″ stainless stick rods they can give you. Then all you have to do is remove the flux and start cutting all the pins you’ll ever need!

I picked up a ’53 or ’54 Evinrude Lightwin (3012; #46506) yesterday and the shear/drive pin is brass.  Does it matter whether the pin is brass or stainless steel?  The chart above says SS for this model but I would think that brass would be better protection as a shear pin.

Why would you want to shear a pin in a motor with such a nice rubber clutch in the prop

[cron78]

Good question, Frank.  I’m not sure if you are kidding about trusting the nice clutch.  I’ll have to look closely at the prop in the daylight tomorrow.

I just found a copy of the owner’s manual and it discusses the “propeller slip clutch”  Should I trust a 70 year old piece of rubber to not have hardened and become less of a slip mechanism?  The illustration in the manual does label the shear pin as “shear pin” and not drive pin.

Anyone had trouble with the old rubber propeller slip clutches?

[frankr]

OK I have to admit they get petrified with age. Still, it seems better to replace the rubber ring and restore the fine feature it was built with.

Sorry for the previous comment.
