Perkins Marine Engines and OEM Spare Parts

Legacy of 85+ Years of Experience in Marine Powering Solutions

Perkins has long been a global leader in marine diesel power, delivering robust and reliable engines to meet the demanding needs of diverse applications. With over 85 years of dedicated marine engine development, Perkins ensures performance excellence for both recreational and commercial vessels.

Perkins marine engines were introduced in the global marine market specifically around 1938. The emergence of the P6 engine series (launched in the mid-1930s) marked the beginning of the brand’s marine venture. Their goal was to use these engines particularly to power light auxiliary craft such as seaplane tenders, air-sea rescue vessels, and launches.

The excellence of robust performance fetched the company the British Admiralty’s demand for lighter, more efficient diesel alternatives to petrol engines. Notably, the P6 marine edition, designated the S6(M), delivered around 120 bhp while maintaining an excellent power-to-weight ratio—about 10 lbs per bhp— delivering fast plane speeds. These engines hold an eminent milestone in history for their contribution towards the rescue of more than 14,000 service members during WWII.

Why Boat Owners Should Upgrade to Perkins Marine Engines

Perkins marine engines stand out in terms of versatility, efficiency, and durability, and several cutting-edge technical features contribute to this:

1. Exceptional Power-to-Weight Ratio

The P6/S6(M) engine series demonstrated a remarkable balance of power and lightness (~10 lbs/bhp), making them ideal for vessels requiring speed and agility without adding extra weight across the hull.

1. Marine-Specific Adaptations

Perkins integrates custom marine enhancements, including seawater heat exchangers, water-cooled turbos, and other regulatory-compliant systems. These adaptations make the engines highly suited to the aquatic environment, ensuring optimal performance and reliability across different vessel types.

1. Advanced Combustion & Electronic Control Systems

The modern marine module lineup features electronic fuel injection, turbocharging, and digital governors, enabling precise and controlled combustion, high fuel efficiency, reduced emissions, and smooth integration with modern vessel monitoring systems. These technologies improve diagnostics, performance optimization, and overall operational endurance.

1. Ease of Maintenance and Customisation

Perkins designs its marine engines to minimize maintenance overhauls and high-end serviceability. The modular architecture allows custom configurations tailored to specific use cases—whether repowering fishing vessels, tugs, ferries, or hybrid propulsion systems. These custom enhancements minimize downtime and support specific marine applications with high efficiency.

1. Lower Operational Costs

Fuel-efficient design, fewer service interruptions, and extended maintenance intervals translate into real value over the engine’s lifecycle. Perkins manufactures OEM parts, maintenance kits, and overhaul kits for all marine engines.
