Default 45 inch dumas shelly foss belt drives

what do you think of my custom made belt drives for my foss
its powered by two american bosh 12 volt motors ( big as pop cans)
the belt drives are made from traxxas nitro 4-tec belts and idler pullys and belts. approx 3-1 reduction
they spin 1/4 stainless shafts ( sealed bearings both ends)
homemade 3 3/4 brass four blade props.
34 amp hour gel cell
no ballast at all and it sits at waterline.

pushes the 60+ pound boat at approx. 14 miles an hour for nine hours without recharging of the main battery

enjoy

Hey! If it works, it's good! And from the sound of it, it's certainly not bad.

On second thought, it's a terrible idea! You ought'a just send them to me...
Should I hold my breath?
