After using my 2006 OBV with the stock prop since the day we pulled it off the lot, I decided to finally change the prop to something more suited to where we live...

We boat at ~6500ft and I knew that the boat wasn't propped right (even though the dealer told us back then "...it'll be fine..."). I never felt it was a big deal, because for one I had nothing to really compare it to and the boat simply 'felt fine'. Skiing at ~36 was good and compared to other boats it pulled me out reasonably fast.

After reading all the great info in this thread and forum, I called Jim @ ACME and his recommendation, based on the info I could give him, was the 1847. He was great to talk to and I am amazed at how he simply nailed it, with his recommendation!!

My brother-in-law dinged up his (stock - Mobius XLV) prop the weekend before and I told him to send it to Nettle Props to see if they can repair it, to use it as a spare.
He checked with JT about the 1847 and JT said it was a great choice, so we went ahead and ordered 2 of them...

Got them installed, last night. We were a bit pressed for time, but took the OBV out for a quick test-drive and we were sitting there amazed at how butter-smooth this boat is now. It doesn't need any time to pop out of the hole and planes out incredibly fast. In fact it felt like it planed the moment I hit the throttle; definitely not the case before.
The entire throttle range feels great and the we can now hit the target 5000 RPM, which before was not possible.

The other good news is that I gained about 2-3 MPH, the lake was kind of lumpy so we will have to see what happens when we find some glass, might be even more, then...
Can't wait to try it out further and see if it changed the skiing wake at all...

The moral of the story: If you boat at altitude and you are running the stock prop, you are probably missing out a bit. Don't ignore it, like I did, for too long!

Kudos to Jim @ ACME Propellers & JT at nettleprops.com!!!
