Yea I built it from the ground up. I'm just gonna mess around with these weedy motors this summer and maybe repower it with a modded zenoah next winter. I just wanted to see if I could convert these old motors to water cooling and get them to run right. Hope to get this thing in the water soon so maybe I can get some video of it's success or failure! :Cheers:You built that from the ground up? Vera impressive! When the time comes Davesmotors has 25cc motors that make real power for not that much outlay of cash.
