Coot ATV Parts

Parts / September 11, 2019

This 1970 COOT articulated amphibious 4×4 was acquired by the seller ten years ago, when it was found in the original owner’s barn. The amphibious off-road vehicle has been well maintained under past and current ownership, and is powered by a rebuilt 12hp Tecumseh air-cooled engine. Optioned with four-wheel steering, the COOT has a 1, 000 pound load capacity on land and 600 pounds in the water. Aside from some minor paintwork, the ATV is unrestored, and all the original parts, fittings, covers, wheels, and tires are present. Service records, owner’s manuals, the engine manual, and copies of sales information are included, and the vehicle is being offered on a bill of sale.

The articulated body can handle up to a 45 degree offset from the front axle to the rear. Both axles are fixed to the sealed steel tubs and there is no suspension. The black steel wheels are fitted with the original military grade tires. This COOT features an optional front mounted roll bar, headlights, tubular steel front bumper, and rear seat.

The walkaround video shown above was provided by the seller and highlights the mechanical features of the COOT.

The utilitarian dash houses an amp meter, choke, ignition and light switch. A single lever operates the disc brake and provides parking and stopping functions. A redundant hand throttle is present to operate the vehicle while walking alongside it. The original steering wheel and vinyl seats show some wear from use.

Underneath the front seat lies the factory 0.5 liter 4-cycle Tecumseh engine that’s matched to a snowmobile/ATV torque converter that has a variable belt drive. There are two spare belts mounted in the tub for easy access in the event of a belt failure. A chain drive to the central drive shaft transfers power to worm drives for the front and rear axles. The engine and mechanicals were gone through earlier this year, and a new fuel tank, carburetor, chain, and drive sprocket were installed. The seller notes that the engine was rebuilt sometime in the past and runs well.

The only notable corrosion was some surface rust in floor of the rear tub that was cleaned, wire brushed, and re-painted. There are said to be no rust throughs anywhere in the tubs, and the drain holes are plugged with brass pipe plugs that can be easily removed. Documents include all service records, parts receipts, owner’s manuals, engine manual, sales brochures, and copies of period ads.
