There is more help available. Mend - runs, not, spin

If it is an inboard engine then the shaft should have a keyway, commonly caled a woodruffe key. Check to see if that has sheared into bits jmcx20 June 2013

jeff beat me to it. remove the nut that holds the prop, remove the prop (some bits (of the old shear pin) may drop out) there will be a pin through the shaft which you will probably have to punch out with a drift.
get a new shear pin from chandlers, these vary in hardness/softness (as well as size) get a selection, use the softest that will allow the engine to run normal operation without breaking.

you've probably sorted it by now but there is usually a shear pin in the shaft at the prop end. It is designed to stop excess damage if the prop catches on something
