You have the QL line of props (a hub and prop 41102353 and 41102310). These are no longer supported as QL has gone out of business and Volvo Penta no longer supports the QL line. For awhile Volvo Penta owned, or controlled, the QL line.
Not to worry however, as I can get you the same type of set up from Mercruiser. They offer a hub and a prop for the Evenrude line.
If you can tell me the diameter and the pitch of your existing prop - estimates are fine - and the horse power of the Evinrude along with an approximate year, I can get you a set up.
As good, if not better than the QL line and about the same price.
