Volvo Penta SP275 aftermarket prop options?

[G__O]

Hello from Finland.

I’ve had an engine&outdrive (AQ131/151+SP275) rebuilt recently and started thinking for a higher pitch propeller.
The issue is that for VP short hub, there seems to be no options left since I have the 14x19 original prop already.

but could I find an aftermarket solution for that? Does any loose hub kit (rubex, etc) fit straight to this shaft?

Or does an VP SX props fit to this?

I know that the short hub is the issue here. For long hub outdrive there seems to be alternatives up to 23” pitch by VP.

Thanks a lot in advance.
