In these low-speed situations, the combustion motor can be shut down so the system can switch to the electric motor for more efficient operation. However, most of their time is spent idling or actively maneuvering to support other vessels. Tugboats employed by harbor services can use a combustion motor to get where they are needed in a hurry. Maintenance costs Annual maintenance is required in both inboard. Today, outboard engines are usually quieter than inboard engines and offer many high-powered options. Performance In the past, outboard engines were not quieter than inboard engines. Hybrid Electric Parallel SerialĮlco’s EP hybrid-electric parallel and serial system benefits commercial and pleasure vessels. The location of the engine is a major difference between an inboard vs. With the flip of a switch, the vessel can switch to exclusively power the electric motor with batteries for situations when the motor would be inefficient. The parallel hybrid-electric configuration allows the motor to drive the propeller directly and charge the batteries while the electric motor is inactive. The parallel hybrid-electric configuration features a diesel or gas motor that is connected to the propeller shaft through an electric motor and a clutching system. The serial hybrid-electric configuration is great for boaters who go on day cruises and want to have a backup power supply should a trip take longer than battery power alone can sustain.
Inboard outboard vs outboard generator#
This provides boaters with the option of running the motor strictly off battery power for a quiet, clean boating experience, or switching to the generator when the batteries are low. Instead, the generator powers the motor and charges the batteries. The difference is the addition of a gas or diesel generator, which has no direct connection to the propeller shaft. Similar to the all electric configuration, the electric motor drives the propeller shaft directly. The batteries can be strategically positioned to keep the boat balanced. Installation is simple, and the motor fits most standard motor mounts. This system is ideal for day cruises in displacement and semi-displacement boats such as sailboats, launches, tenders, and sloops. With the all electric configuration, an electric motor powered by batteries drives the propeller shaft.
