I used the instructions on this site to fix my Aquabot turbo motor. After opening up the motor I found that one of the small gears on the transmission was stripped. I purchased Replacement Pinion Gear 4mm - 15T SKU: GS0460-4-15 from Hobby King to fix it. First you will need to ream out the hole slightly...I used sandpaper wrapped around a slightly smaller drill bit. then you will need to grind or cut a mm or 2 from the non allen key side of the gear. Then install and refit the motor. Has been working for a month with no issues.
