Well yesterday I found out that my 35HP diesel will not fit in the bottom of the tub with the belt driven fan/radiator,,,Just about 3in too long with the clutch on the motor,,,SSSSSSSSSSSSoooooooooooo,I guess I will mount the radiator kinda laying flat atop the t-20 with a 16in pusher electric fan setup,,,I think its gonna look pertty cool,,,
