  • Prop removal

    I cant seem to figure out how to remove the prop fro my 1973 Arro. All m other outboards use the nut/cotter pin setup. Any ideas? Here is a pic.

    I'm guessing along with you. I think that cone is a cover for a nut or pin. Probably pressed in, or has a threaded pilot. Based on your prop's rotation, I suspect any threads would be std. RH. It won't be pretty, but it won't chew up that cone any more...so I'd first try prying it out. Then use a pipe wrench to see if it turns out. Let us know what you figure out.

      Found solution....O-ring at base of cone is split and hides a pin similar to shear pin. Removed o-ring, punch out pin and cone slides off. Slide off prop and exposes shear pin and waterpump.
