British Seagull

British Seagull outboards are iconic symbols of classic maritime engineering, designed with the singular goal of being 'The Best Outboard Motor in the World' for rugged simplicity.

Produced in England from the 1930s until the 1990s, these engines were distinctive for their massive reduction-gear propellers and exposed mechanical components. Unlike high-revving modern engines, Seagulls were designed to push heavy displacement hulls with massive torque at low RPMs. They featured unique engineering quirks, such as the lack of a traditional neutral gear on many models and a reliance on high-oil fuel mixtures (as heavy as 10:1 in early years). Prized by traditional sailors and collectors, a British Seagull is recognized by its polished brass tank and cast-iron cylinder. They are engineered to survive in conditions that would destroy a modern engine, thriving on a philosophy of indestructible mechanical honesty.
