Hi there, I know your intention is to try and save some extra money by looking around for a used gear set but unfortunately iboats doesn't permit any sort of solicitation on open forums so about the best we can do at this point is try looking up your OEM part numbers then do an online search for them.
It looks like your gear part numbers are 43-822163T1 GEAR, Reverse (22 Teeth) ,..., 43-822162T2 --GEAR, Forward (22 Teeth) and 43-822161T2 --GEAR, Pinion (12 Teeth)
Then in rare cases, keep an eye on your privet message to light up as you may get a response from some of iboats helpful forum members that may have something lying around the shop.
