I have a Prop question

[cozza]

Hi all i need to know what the Numbers mean on the Volvo Penta Duo props. I know what the letters mean like A is for Diesel and B is for Petrol, but the numbers I'm a bit stumped on. Like A3 and A8 or A10?? .

If someone can help me out much appreciated
cheers

Most of us are stumped as well. While this is clearly a prop question;I think you may do better in the Volvo I/O forum.
Tell them I sent you.
