Prop ?
 

I'm looking to upgrade my prop I have a sanger 2006 sanger v215 I'm adding the wake makers tank buster kit with 750 sacs and I boat at an high elevation around 6000 feet just wondering what prop to get that will give me my power back I've done some research and I think the acme 911 is what I need but I'm not sure thanks for any info

Yes, the 911 will give you the performance you need. You could use a 2083 which is a 9" pitch instead of the 10.5" of the 911 prop if you are into surfing but it won't be useful if you ever run at lower elevations. Your top speed with the 911 is low 40's and it would be high 30's with the 2083.
At 6000 feet you are down over 20% on power. The 911 gives you that back through torque multiplication.
I use the 911 on my D215 at altitudes of 1600' and 3000'. It did not decrease my top speed compared to my 515 12" pitch prop as I could not use more of the RPM range on my 330 Scorpion.
Call Acme if you want. They listen and usually come up with a good selection.

If only wakeboarding get a Acme 15"x12. Not sure if it will fit on your boat but has lots of power to get on plane. Not a lot of top end but really helped my LSV at 3800'

We put the 911 on our sanger v230 last summer and it changed our boat! We run 750's in the rear and 500 midship

Yes acme 911. I have it on my 215 and I've had 3500# in ballast and it pulled that great still

I run the 750's in the rear, stock 500 in the front hull and a 1000# bow triangle and the wake is awesome!! It pulls that out easily at sea level

Another vote for the 91. You will loose some top end speed when cruising, but the tork outta the hole more than makes up for the loss of top speed!

911!! Plus helps hold speed easier due to more sensitivity.
