Hi all, now that the mini mini van is done I am going to move on to the COOT. I bought it couple years ago and used it one season on the mountain, the previous owner changed the drive system from the original Salsbury clutch system and transmission with 2 forward and 1 reverse to hydrostatic. With the Salisbury clutch in low it is something like 68:1 so it will climb over anything, in second it will do over 20mph. The hydrostatic system didn't have enough gear spread in it to climb or go fast. It had a 20hp Kohler that you could stall out. I recently bought the Salsbury clutch system and I already had the original trans. Today I stripped it out completely to do the conversion I had to get a new engine also. The kohler has a 1-1/4" pto shaft and there is no clutch made for that size. I bought a new 16hp motor and that is plenty, as they originally had 12hp. Reading on the COOT forum the 20 hp and 22 hp engines tend to break drive parts and add weight. Tomorrow I will start making a new engine mount plate as what was there is hokie and I want to clean up the installation. Its not going to take much time ( a couple weekends ) and I will be playing with it before you know it. Also I am going to weld up all the holes in the tubs so it will be amphibious again.I have been on the Coot forum getting ideas, I want to modify the roll cage and add a winch at a later date.
