Some good info in that thread. I was definitely told of it in 2011 by Bret Potts. And then Mark Sher also told me personally it helped a lot, but made the boat pull significantly in one direction. I did not know it took an allen wrench at the prop though. I had assumed this adjustment was being made at the polar bear events, but I know the boat wasn't pulled out of the water in 2011. It was pulled out of the water this year, but not before the goofy session.
Every boat at the polar bear does each side, and this year we had 3 groups, and one group was goofy. The centurion 211 did 3 sessions, regular, regular, goofy. I am pretty sure it came out of the water after first session, we had lunch, and then we switched groups on the water for the second to third sessions, which you can see at the "stinger" or beginning of the video when the titles are being displayed.
I will try to find out about this year, but my guess is that if it takes an allen wrench at the rudder, it was not adjusted for the above videos, which is not bad news, but more good news. I guess that would mean if you wanted to make that adjustment the wake on the goofy side would have been a bit cleaner in the above videos.
I have heard it suggested, and by boat owners, not any manufacturer , that many boats have offset props. Here is a picture.
This is from a mastercraft, I believe. So for instance, to remove the shaft, you don't have to remove the prop on this boat, but on Tiges for instance, the prop is NOT offset, and you have to remove the prop to remove the shaft.
I wonder if the boats that have offset props are the same ones that have more of this issue with the goofy wakes, and the ones that are not offset do not?
I truly do not know, but that "experimenter" and "tinkerer" in me wonders about this. I mean, is the Avalanche offset different?
I know a lot of people say its prop rotation, and I have had people call me a liar and say that I am not telling the truth with our RZ2 and 24Ve. That I must be weighting the boat or at least adjusting the TAPS plate differently from one side to the other. Because there is no way my wakes on each side could be the same like in the videos. But I think there have been enough people out on our boats, and at these events at attest that I am telling the truth.
Sorry, not trying to get into any "my boat is better" argument, but this prop offset issue has been on my mind of late, and it makes me curious. The other question, is that if the prop IS offset, does it make the wake on one side BETTER than it would be if it wasn't? So would my Tige have an even cleaner wake on the regular side than the goofy if my prop was offset?
All that said, I have NO FRICKIN CLUE. ;-) Fun to ponder on the internets though.
