The Geoduck program is a craft designed to use the smallest commonly available automobile engine, the 1000cc G-10 Suzuki (Geo Metro) engine, 3 cylinder and 45hp at 4200rpm. An inline 4 cylinder engine can also be used, and if the builder desires, a second lift engine, 18hp Briggs, can be used for a two engine craft. The single engine version is preferred though for a smooth quiet ride.The hull is 16 X 8 feet, and can be extended to 18 feet for easier planeout and more interior room. The top speed is 37mph and fuel use is 2 gallons per hour. This sev can haul over 1000 lbs payload over big and small waters and has exceptional athletic abilities over rough terrain.The added hull length and 1.3L engine will increase the load to 1200 lbs.
