Volvo Penta D1-30 – Inboard Diesel Engine 30 HP

Volvo Penta D1-30 30 HP – Compact Sailboat Repower Diesel

Solving the space constraints of smaller sailing yacht engine rooms, the Volvo Penta D1-30 produces 30 HP at 3200 RPM in a remarkably compact 3-cylinder footprint. This engine is a cornerstone of the American small-sailboat community, offering a lightweight auxiliary power source that minimizes the impact on vessel trim. For the American sailor, the D1-30 provides the perfect blend of reliability and performance, providing enough thrust to motor through heavy head-seas while enjoying the fuel economy of a refined 1.1-liter diesel block.

Meeting all USA EPA Tier 3 standards, the D1-30 emphasizes clean-burning performance and exceptionally low vibration levels for a superior environment on deck. The engine features an oversized 115A alternator as standard, a critical feature for American boaters who rely on house battery banks for modern GPS and refrigeration systems. Its freshwater cooling system is engineered to protect internal components from the corrosive high-salinity conditions common in USA coastal waters, ensuring decades of dependable service for American voyagers.
