Volvo Penta 5.7GiE-300-K Marine Engine The Volvo Penta 5.7GiE-300-K is a high-performance, gasoline-fueled inboard marine engine engineered for dependable propulsion in demanding aquatic environments. Introduced in 2008, this V8 powerhouse delivers crankshaft power of 280 hp (206 kW) at 2,500 rpm, making it a cornerstone for mid-sized vessels requiring robust torque and smooth operation. Key technical specifications underscore its engineering excellence: an 8-cylinder V-type configuration optimizes compactness and balance, while the standard marine pump-feed gasoline system ensures reliable fuel delivery. The engine features a fully enclosed inboard design with corrosion-resistant materials and coatings to combat saltwater exposure, humidity, and thermal stresses. Its water-cooled system efficiently dissipates heat, complemented by an integrated oil cooler for sustained optimal lubrication during extended runs. The back-extract exhaust manifold configuration minimizes noise and enhances gas evacuation, aligning with low-emission standards such as Tier I or II regulations for eco-sensitive waterways. Marine-specific benefits elevate the 5.7GiE-300-K’s suitability for harsh conditions. Its durable construction withstands vibrations, prolonged high-RPM operation, and environmental fluctuations, promoting longevity and reduced downtime. The compact V8 layout lowers the center of gravity, enhancing vessel stability and handling in rough seas. Fuel efficiency is achieved through advanced combustion tuning, balancing potent output with economical consumption to lower operational costs over time. Performance characteristics include quiet, vibration-dampened operation for onboard comfort, alongside exceptional reliability backed by Volvo Penta’s modular serviceability—accessible components and standardized parts simplify maintenance. Ideal for displacement and semi-displacement hulls, this engine excels in applications like recreational cruisers, luxury yachts, and light commercial vessels, from coastal patrols to inland waterways. Supported by Volvo Penta’s global service network and comprehensive warranty, the 5.7GiE-300-K empowers boat builders and owners with versatile, low-maintenance propulsion that prioritizes power, efficiency, and seaworthiness.
