Hello,<br /><br />It seems when I want to buy a prop for this 72 Johnson 100, that i usaully get listings up to 1968, and then again after 1974. The only jonny V-4 prop i can find anywhere (on the net)is for a "125 hp thru hub 13 spline."<br /><br />Should I order based on the 68?<br /><br />Any help much appreciated, i just want a "gear down" prop for pulling skiers days.
