I run the 13.7x19.5 and I do alot of longline footing. It works great.

I have tested 4 different props for my 197 with the LY6 and I found that the ACME 1281 was the best for my purposes. It is a 3 blade CNC 13.25x15 LH with .090 cup. It has the second best hole shot of all the props I tested with the best top end of all the props I tested. When I say second best hole shot it wasn't second by much. I also remember that the ACME was turning about 300-400 less RPMs at 36 mph than the stock prop. If you are planning on slalom skiing for the most part then the stock prop will be just fine. If you like to barefoot at higher speeds I would recommend the ACME.

Prop Dimensions........... Manufacturer........ 0-36 mph time.......... Top Speed .............RPMs @ WOT
13.7 X 15........................... OJ........................ 7.5 sec.....................45 mph....................4840

13 X 14.............................. OJ........................ 7 sec....................... 45.5 mph ................5050

13.25 X 15 .........................ACME ..................6 sec ......................47 mph ....................5400

13 X 12 (Stock).................. OJ........................ 6 Sec ......................45 mph.................... 5500

I am also running the acme 13.25x15 from acme for slalom and barefoot. I had Bill at Acme add a little more cup to bring the rpm's down a little for slalom. It will bring the LY6 to 3600 at 36mph. I also have the Acme 13.25x14 3 blade for wakeboarding. We run 1500+ ballast in the 197 and this prop runs great. The 13.25x14 will hit the rev limiter when not weighted, but it is rare you need to be at Wide Open Throttle.
