Evinrude impeller pin question

Hello all,

I managed to loose the pin that keys the impeller to the drive shaft.  It looks like a 1/8” pin, approx .300” long is what is needed.  I haven’t found a local source that sells solid pins and hate the idea of paying $7 plus shipping for a correct one if a simple roll pin will work (which I already have a selection of).  Any words of wisdom on replacing the pin ?  Unfortunately, I don’t have a metal lathe to make one.
thanks

1/8″ stainless rod is readily available in most areas.  Or how about an unthreaded section of a stainless steel screw?

I would not advise using a roll pin.

How about a piece of a nail?  Maybe a welding rod stub?  The flux will sand off an electric welder rod easily!   How about a coat hanger?  There are some that are close to 1/8″  Those prices are nuts!

I thought it was a very bad idea to use anything but the correct shear pin as the use of a material that has a much higher shear strength will defeat the purpose of the shear pin and allow the forces from a prop strike to damage engine internals.

When I was young and dumb I used sections I’d cut off from a brass rod my buddy gave me.  they worked a bit, but were too soft and didn’t last long.  Finding out exactly what the metalurgy is on those shear pins and getting a length of rod would be the way to go.

Thanks for the feedback.  I was thinking that a softer steel might corrode too much.  I recall that hardened steels tend to rust less and I think the original was a hardened pin.
