I have an 83 Stars and Stripes with the 351W and the Borg-Warner Velvet Drive. I am not sure what prop I am running but I am guessing it is stock. It is a 3 blade. I was wondering if there was a prop that I could get that would allow for more speed at a lower RPM. I don't know much at all about props. I wakeboard, kneeboard, tube, ski, and cruise around the lake alot. I am not sure how fast I am going ever because my dual speedos are constantly clogged up. It just doesn't seem like it will move very quickly at all without running a zillion RPM's. Any info would be appreciated!! Thanks!!! -Cody

I have a stock 13x13 three blade. I don't have the powerslot trans, just the standard 1:1. I'm able to get a top speed of 43mph at 4800rpm's.

PS...I pull skiers based on rpm's. I've had far too many problems with the speedo's clogging up that I've found rpm's to be more consistent. I figure rpm's are fairly close to mph's.

Cody - What is the transmission ratio? What is the max RPM the current propeller will turn? Eric @ ojprops

I am actually not sure. I have had it to about 4200 RPM's I believe but it wasn't moving very fast and it sounded like it was going to blow up so I just have never had it past that.
