Our drives that came with our Oasis 2010 are new and never used (everything is frozen outside :lol: )
While checking the drives I dicovered a "thunk" on both of them.
It's the pin from the pedal adjustment assembly that moves in the selected hole from the drum.
When changing direction with the pedals, the pin moves from one side to another in the hole (less than 1mm), at the pedalend it gives a "thunk of 3mm.

As we never used our drives in the water, I'm not sure at all it will be felt in normal use because you normally only push on the pedals.
I wass told sportcyclists also pull on their pedals with the pedalstraps, they will certainly feel the "thunk"

If you don't change the adjustment settings often, we remove the adjustment hardware and bolt the drives with SS hardware.

This is normal. There is a little slack built in so when you adjust the pedal positions the pins have adequate room to snap in all the way without binding. As you suspect, the pedals normally are pushed forward but not pulled back, so it isn't noticed on the water.

While it is possible to pull back on the pedals, it is unusual to pull back hard enough to actually move the pedal adjustment pin back and forth in its hole. If you do, you can hear the pins clicking but it doesn't hurt anything. 8)
