Hi
I'm trying to install the SS prop from my old OMC Cobra sterndrive to my new SEI116 drive. After searching this forum I thought that and OMC prop could fit Alpha1 without problems. But that is not true. The center hub is too long and I can't secure the bolt using the Mercruiser "Borg ring" and there are no hole in the prop shaft to secure it using OMC prop hardware. Different thrust washers won't move the prop backwards enough and removing the thrust washer causes the prop to hit the outdrive casing (and still no enough splines to secure the prop). Anyone experienced with converting this type of a propeller to fit Alpha1? I'd like to use it in the future as well, because I think it's a fine prop. Although if the conversion involves too much labor, I might give up.
