I got a 12. inch pneumatic wheel and tire from Princess auto that had a bearing with a 3/4 inch bore in it. I married this to a 6 inch x 3/4 inch axel and a piece of 2 inch channel steel. I bolted this to my engine mount with two bolts and wing nuts. It takes less than a minute to put on and off my toon. You hold the leg rests like they were the two handles of a wheel barrow and viola your off. Using it like a wheelbarrow I can put the electric motor the battery and all my stuff on the toon and wheel it down to the lake. Easy as pie. The Wheel,tire and axel cost me $11.00 the channel steel was something I found at the scrap yard and the guy said to just take it. Total cost was $15.00 or so. I would take a pic of it but its stored away for the ice season.
