Volvo Penta D6-340 340 HP – High-Efficiency Marine Inboard

Eliminating the noise and vibration typically associated with high-displacement marine engines is the core achievement of the Volvo Penta D6-340. Producing 340 HP at 3500 RPM, this engine is specifically engineered for American cruisers and trawlers that prioritize passenger comfort and operational economy. The refined common-rail injection system ensures optimal fuel atomization, providing USA boaters with a smoke-free transom and a quiet cockpit environment during long-distance voyages across the Great Lakes or the Atlantic Intracoastal Waterway.

Adhering to strict USA EPA Tier 3 regulations, the D6-340 utilizes advanced electronic management to maintain peak performance while minimizing its environmental footprint. The engine is designed for easy serviceability, with all maintenance points conveniently located for accessibility in the compact engine rooms of American-built yachts. Its robust 115-amp alternator is specifically sized to handle the house-load demands of modern American marine electronics, ensuring house battery banks remain fully charged during offshore transits.
