amperetta HYBRID-DRIVE

amperetta HYBRID-DRIVE is the powerful, compact, and easy-to-use full hybrid on the water. A strong electric motor is available for acurate maneuvering as well as for slow and medium cruising. It runs almost silently. If you need more power, the internal combustion engine takes its place and uses the electric motor as a generator to recharge the battery without the need to intervene. Fuel savings up to 50%. The system range is thereby even higher than with pure combustion drives.

Venice goes Hybrid

amperetta teams up with Classic Boats Venice to revamp one of the most beautiful boats in the lagoon area. Sweet Molly is an example of boating elegance and sophistication. Built in 1938, restored in 2019, and reengineered for 2020. This cinematic boat built in Sweden has called Classic Boats Venice her new home for the past 2 years, where guests get the chance to experience Venice aboard this magical boat. In 2020, this one of a kind beauty will turn more heads with the inclusion of an Amperetta state of the art hybrid engine.


The amperetta HYBRID-DRIVE

Build of the HYBRID-DRIVE

A conventional marine diesel engine is connected to one of our hybrid modules on its output shaft. The modules consist of a separating clutch and a high-performance electric motor. Our HCM (hybrid control module) controls whether the clutch is closed or opened. The electronics use power from the battery for the electric motor when driving or, when the diesel engine is running, flow back into the battery from the electric motor (which then serves as a generator) and recharge it.


amperetta HYBRID-DRIVE is currently available for a growing number of donor engine families, such as:

  • 419108

    VolvoPenta D3
  • 419108

    VolvoPenta D4
  • 419108

    VolvoPenta D6

Other compatible engines are in preparation. Please send an inquiry.

additional components (control/power management, cooling system etc.): typical weight ca. 85 kg

Possible uses of the hybrid drive

Due to its compact dimensions, it can be used in virtually any boat designed for built-in machines.
Whether a shaft drive or a Z-Drive, amperetta HYBRID-DRIVE is suitable for both.

The following driving modes are possible:

full hybrid

The hybrid mode combines the advantages of both drive types. It reacts actively to the current power demand with automatic change to the optimal drive type.

electronic mode

The super-quiet electric mode allows purely electric driving even on water areas, which are limited for boats with internal combustion engines. They drive without emissions and can thus also drive through nature reserves.

diesel mode

The diesel mode uses the power of the diesel engine for propulsion of the boat and excess power reserves for recharging the battery system.

Upgrade your vessel

You want to experience the future with amperetta HYBRID-DRIVE in your boat? Let's get started! amperetta HYBRID-DRIVE requires little more space than a conventional combustion engine, making it the natural choice for refits with limited space in the engine compartment. amperetta HYBRID-DRIVE is compatible with stern-drive and inboard designs.

Contact our friendly team if you would like to get more information about possible refit / upgrading options for existing propulsion systems or to (re-)fit a completely new powertrain in your boat, whether existing or new build.
