Mirage Drive Adjustment - Rear fin slaps hull

Hi folks,
Am now enjoying my new 2010 Outback that Hobie sent to replace my 2009 one.
I transferred my 2009 V2 drive unit to the 2010 Outback.
However, I have now discovered that the rear fin is slapping the hull on the port side when at a full pedal extension in one direction and leaving a large gap on the starboard side (maybe an inch or so) when at the other full pedal extension. This may have been happening on my 2009 but I just now noticed it.
Is there a way to adjust the fin so that there is an equal amount of gap on both sides between the hull and the fin and still keep the forward fin and rear fin in alignment??

Any help would be appreciated.

Have you checked the number of holes for the length adjustment. sounds like you are one hole difference in the adjustment of the peddle length. Just a quick thought about the difference. Good Luck

Be sure the drive is installed correctly (level). This may indicate a drive that is tipped forward and not resting on the forward ledge.

Can this post from Roadrunner help you?

Thanks to Thinwater, Matt, Thierry and Roadrunner.
I was able to adjust the drive unit to eliminate the hull slap.
I was fortunate to have a 2nd drive unit as a model and used it to adjust the one that slapped the hull.
I observed how the chains were adjusted on it and then adjusted the problem drive to have similar chain measurements by turning the adjustment nuts. I also looked at the procedures offered by Matt and Roadrunner.
