MasPower Marine Generators

Marine Generators Depot supports MasPower Marine Generators for boat and yacht owners seeking compact diesel auxiliary power, replacement gensets, and support for established MasPower installations. The marine range was developed by Mastry and used proven Yanmar diesel engines, combining marine-specific cooling, vibration isolation, remote monitoring, and compact generator packaging for onboard electrical generation. Mastry’s own historical application records identify several MasPower/Mastry models as marine generator installations.

Popular MasPower marine gensets include the MP6M 6kW, MP9M 9kW, MP11M 11kW, and MP13M 13kW marine generators, together with sound-attenuated “MSA” versions of several models. These power classes suit many recreational boats and motor yachts requiring electricity for battery chargers, refrigeration, lighting, pumps, galley appliances, and appropriately sized marine air-conditioning systems.

A distinctive feature of these marine diesel generators is their Yanmar-powered 1800 RPM configuration. Depending on model, published MasPower specifications included brushless alternators, stainless-steel exhaust manifolds, vibration mounts, engine-mounted monitoring panels, remote controls, AC circuit protection, and stainless hardware. Sound-enclosed versions were also produced for buyers prioritizing a quiet yacht generator and reduced machinery-space noise.

For generator sizing, a 6kW boat generator may be appropriate for moderate hotel loads, while 9kW, 11kW, or 13kW yacht generators provide greater capacity where several AC consumers operate together. Generator selection should nevertheless be based on the vessel’s actual load profile, voltage, frequency, phase, motor-starting demand, installation space, and cooling arrangement rather than kW rating alone.

MasPower is particularly relevant today for marine generator replacement and repower searches. Several previously marketed MasPower marine models are now identified as discontinued by current marine retailers, including MP6M, MP9M, MP11M, and MP13M variants. Marine Generators Depot can therefore help customers compare an existing MasPower genset with suitable replacement options using the original model, serial number, dimensions, electrical specification, mounting arrangement, exhaust, and cooling connections.

Parts identification can also be important for owners maintaining older MasPower marine generators. Historical models include the MP5.5M, MP8M, MP16M, MP18M, and MP22.5M families, with Mastry records showing multiple Yanmar engine applications across these gensets. Providing the generator identification plate, engine model, serial number, and required part number helps distinguish between service components for legacy units and components intended for currently supported generator systems.

Whether you are maintaining a 6kW MasPower marine generator, replacing a 9kW or 11kW yacht genset, or searching for an alternative to a discontinued 13kW or larger marine diesel generator, Marine Generators Depot can assist with technical comparison, replacement sourcing, parts enquiries, and worldwide supply options for recreational and professional marine applications.
