Propeller question please advise

[TeamJoseph]

Hi All

we are based in South Africa and we boat at a small lake about 4300 Ft above sea level.

we have a Moomba Mobius LSV 2005 model
I am struggling a bit to get a few more miles out of my boat as my kids are now barefoot waterskiing.
When towing a barfoot waterskier I am getting a max of 38 miles.

I am currently running a 13.5 x 17.5 propeller ( 4 blade)
What prop size / pitch would be ideal or what would be the std fitted propeller that should be used

When we got the boat it was fitted with a 4 blade propeller size 13 x 15.5 which I still have but it had more torque but less speed

I would really appreciate if you could direct me in the right direction.

regards

TJ

If you can find an 18.5" pitch or higher it should get you the top end you're looking for.

I would start with this chart on the ACME site.

You don't want to change the diameter much as you may have issues trailering if you go to a larger diameter. I would think something like the ACME 907 that is 13.5 x 19 would get you the top end you are seeking.

It is available from Wakemakers but perhaps you can find somewhere closer. Also, your elevation may affect this so I would be tempted to contact Nettles or Wakemakers to verify that it will actually work at your elevation.
