Volvo Penta D3-110I-A: Reliable Diesel Propulsion for Marine Excellence The Volvo Penta D3-110I-A is a compact, inline 5-cylinder diesel engine engineered for dependable marine propulsion, powering a wide array of vessels with efficiency and robustness. Produced between 2004 and 2006, this engine exemplifies Volvo Penta’s commitment to marine-specific innovation, delivering 106 hp (78 kW) of crankshaft power through its durable diesel fuel system. Key technical specifications underscore its engineering prowess: an inline configuration optimizes spatial efficiency for stern-drive or shaft-line installations, while the modular design facilitates seamless integration with Volvo Penta’s PS Series transmissions or compatible third-party units. Adhering to pre-Euro IV emissions standards, it employs raw-water cooling for superior thermal management in saline environments, coupled with corrosion-resistant construction to withstand harsh marine conditions. The 5-cylinder layout ensures smooth power delivery, with inherent diesel traits promoting longevity and fuel economy. In marine applications, the D3-110I-A shines through its marine-optimized benefits, including vibration dampening and acoustic isolation for enhanced onboard comfort, and a high power-to-weight ratio that minimizes hull impact without sacrificing performance. Its robust build resists the rigors of saltwater exposure and continuous operation, reducing maintenance intervals and operational costs—bolstered by Volvo Penta’s global dealer network for readily available service and parts. Performance-wise, this engine offers consistent torque for reliable acceleration and cruising, excelling in fuel-efficient long-haul scenarios while maintaining low emissions for environmentally conscious operations. Ideal for medium-sized displacement hulls (20–40 feet), such as recreational yachts, fishing trawlers, or coastal workboats, the D3-110I-A embodies safety and reliability—evident in its symbolic alignment with marine lifesaving standards—making it a trusted choice for operators seeking balanced propulsion without compromise.
