Prop Size?

17" P you should be on the money, somthing like a SWI

The only thing on the old prop is "19M" no other markings. I borrowed one to get me thru the week but it's got 1/8" - 1/4" of play on the shaft. Not sure if I should use it?

I would gues a 19 with that set up, even before you posted it had a 19M on it. If you can find a mercury Mirage plus 19 P, give it a try, A lot of people have good performance with eth Mirage on Yamaha props. If it has the late style replapceable hub, it should fit on your Yamaha using the yamaha hardware

Yeah, those Mirage props are great on deep V hulls...lotta PUSH!!...I tried a Mirage 15 1/2 x 17 on my Honda...perfect numbers, but was too heavy and caused a rattle in lower unit at idle...went to the 15 1/4 x 17 Power Tech, got same numbers, but no rattle...
