The Volvo Penta D8-IPS700 is an integrated marine propulsion package built around the in-line 6-cylinder D8 engine, a 7.7-liter common-rail diesel with twin-entry turbocharger and compressor. Paired with the IPS15 pod, forward-facing twin counter-rotating propellers, and the Electronic Vessel Control system, this package delivers strong low-rpm response, efficient propulsion, and precise maneuverability. The system is designed for twin and triple installations in planing hulls, supporting vessel speeds from approximately 20 to 40 knots.

Electronic Vessel Control (EVC):
The Electronic Vessel Control system integrates engines, electronics, and optional features such as Joystick Docking, Dynamic Positioning System, and Glass Cockpit displays. The system supports safe docking, precise low-speed handling, and simplified operation, with built-in redundancy to maintain backup control when required.
Comfort and Maneuverability:
Steerable IPS pods provide excellent slow-speed maneuverability and confident high-speed handling, even in confined waters. Forward-facing propellers operate in undisturbed water, helping to improve propulsion efficiency. The integrated rubber suspension and seal system helps absorb propulsion forces and vibration, while exhaust gases are discharged through the pods into the propeller wash to enhance onboard comfort.
Applications:
- High-speed passenger ferries
- Pilot boats and patrol vessels
- Search and rescue boats
- Coast guard and law enforcement craft
- Crew transfer vessels
- Private yachts and luxury motorboats
- Planing hull vessels requiring twin or triple IPS installations
