Cobra Prop vs Alpha One Prop

[Faerbairn]

I currently have a 14 x 21 prop on my 1991 Sea Ray 4.3L V6 190hp with Alpha One out drive.

I have a nice Stainless steel 14 x 19 prop left over from my 1987 OMC Cobra 4.3L 175hp. It fits right onto the Prop spline of my new Alpha. It's perfect but the Cobra uses the cotter pin to keep the prop nut in place and the Alpha uses a castle nut washer tab thing.

Is there any way to buy something to make the Cobra prop work on my Alpha One?

Thanks for your help

Yes, I can use the Alpha One tabbed castle castle nut, but what will lock it in place? Doesn't it need something to keep it there so it doesn't spin off?

Ayuh,... The castle locks to the splines,.. The tab washer locks to the castle...
And, That all holds the Nut...
