What prop for my Yamaha 50?

[billt23]

I have an '02 21ft.Party Barge (Pontoon) with an '02 Yamaha 50 w/oil injection. It came with an aluminum prop. I would like to get a stainless steel prop since I know it's just a matter of time before I hit a stump. What size should I get? I'm looking on Ebay but don't know what to look for. Help!<br />billt23

Is it a 50F or a 50G?<br />(the first one shares powerhead w/ the 40, 698cc, the G shares with the 60/70HP , 849cc. Different lower units on those,<br />Which size prop do you use today? <br /><br />Another thing to consider is that an SS prop can transmit more impact to the lower unit , thus potential for doing more damage if you get a good hit. Performance-wise I think your gain will be neglible with a SS prop and I'd go for aluminum.
