[OMC-Boats] Prop info.

I think the prop should slide easily over the shaft with no binding
therefore the purpose of the shear pin. Thats the way mine are and I have
used several props on the 69 Rogue 210. There is a thrust washer between
prop and shear pin (Part # 310594) - not absolutely necessary for use but
you should have one on there eventually. The thrust washer is brass I think.
Nice pictures of your Explorer - the hull is similar to the Rogue. Look on
the shaft or prop for a burr or paint or glue or something - something
doesn't sound right with the fit. I use a little grease on the shaft just to
combat corrosion but thats my own preference. TK
