Perkins M115T Marine Propulsion Engine The Perkins M115T is a robust, turbocharged diesel engine engineered specifically for inboard marine propulsion, delivering reliable power to boats and yachts navigating demanding waterways. As a hallmark of Perkins’ legacy in marine engineering, this 4-cylinder, 4-stroke diesel unit combines compact design with proven durability, making it an ideal choice for vessel operators seeking consistent performance without compromise. At its core, the M115T boasts a power output of 114 horsepower (83 kW) at a minimum operating speed of 2,400 RPM, driven by a displacement of 3,990 cm³ (bore: 100 mm, stroke: 127 mm). Weighing just 423 kg (932 lbs) and measuring 1,160 mm in length, 703 mm in width, and 830 mm in height, its footprint is optimized for seamless integration into space-limited hulls. The inboard configuration, paired with an electric start system, ensures effortless ignition even in adverse conditions, while the freshwater cooling circuit safeguards against the corrosive effects of saltwater exposure. Tailored for marine rigors, the M115T features turbocharged aspiration that boosts low-end torque and fuel efficiency—achieving an impressive 0.279 mpg per hp—reducing operational costs and minimizing exhaust emissions to comply with stringent environmental regulations. Constructed with marine-grade materials, it excels in resisting vibrations, moisture, and salinity, thereby extending service intervals and enhancing overall vessel longevity. Performance-wise, the engine provides smooth, responsive power delivery for sustained cruising, with enhanced throttle response ideal for handling heavy loads or strong currents. Its turbulence-resistant architecture maintains stability across varying sea states, offering peace of mind for extended voyages. Suited for small to mid-sized recreational boats, fishing vessels, and coastal yachts, the Perkins M115T empowers mariners with dependable propulsion that balances efficiency, power, and resilience—empowering adventures on open waters with unyielding reliability.
