Brit Engineering Co Ltd. Brit IMP Marine Engine The Brit Engineering Co Ltd. Brit IMP is a compact, gasoline-powered inboard marine engine engineered for reliable propulsion in small recreational vessels. As a 4-stroke single-cylinder unit, it delivers consistent power for auxiliary or primary drive systems, ensuring smooth operation in diverse marine environments. Key technical specifications underscore its practicality: Producing 5 horsepower (3 kW) of continuous output—likely optimized at 3,600 RPM for standard small marine applications—the engine features a bore and stroke of 2.75 x 2.75 inches, facilitating efficient combustion. Weighing just 67 kg (147 lbs), it measures 538 mm (21 inches) in length and 312 mm (12.3 inches) in height, making it highly maneuverable for installation. Equipped with an electric start system and fueled by readily available gasoline, the Brit IMP integrates seamlessly via inboard coupling to hull-mounted gearboxes or transom housing units, with no specified reduction gear for direct-drive simplicity. Tailored for marine demands, this engine excels in corrosion-resistant construction—essential for saltwater exposure—and incorporates a 4-stroke cycle for superior fuel efficiency, reduced emissions, and quieter performance compared to 2-stroke alternatives. The “Back Extract” exhaust layout likely enhances cooling to prevent overheating during prolonged operation, while its lightweight design promotes optimal weight distribution for vessel stability and easy portability between boats or storage. Performance-wise, the Brit IMP offers dependable torque at moderate speeds, balancing power with economical fuel consumption to minimize operational costs on extended outings. Its low noise profile suits leisure boating, and the electric start ensures effortless ignition even in humid conditions. Ideal for dinghies, tenders, inflatables, flat-bottom skiffs, or as auxiliary propulsion for sailboats, the Brit IMP combines simplicity and adaptability, making it a go-to choice for casual mariners seeking robust, space-efficient propulsion without compromising on reliability.
