Efficient charging!
Today's sailboats consume a lot of electricity. That's why we've equipped the D-series with by far the best battery charger in the business – as standard equipment. It's a 115 A alternator with a built-in charging sensor that gives correct voltage at the batteries. (The D3 has a 140 A alternator.) An optional extra alternator is easy to install.
Reliable starts – simple stops
With automatic pre-heating and the relay-activated starter solenoid, starts are reliable. Electric stop is standard on all D-series engines. D1/D2 feature push-button, D3/D4 use an ignition key.
Torque for sailboats
Volvo Penta D-series engines deliver high torque even at low revs. That means plenty of power and quick response to your commands when maneuvering in a harbor. It also enables the most powerful alternators in the business.
Low revs = high comfort
The D-series engines are rated at just 2800–3200 rpm, wich means a mere 1700–2500 rpm at cruising speed. The result is minimal vibrations and low noise – wich are further reduced if you have Saildrive.
