The Mase IS 13.04 Marine Generator is one of the most advanced and reliable marine gensets available today. Delivering 13kW of continuous power, this boat generator is powered by a Yanmar diesel engine running at 1800 RPM. Specifically engineered for onboard marine applications, the Mase IS 13.04 is quiet, compact, fuel-efficient, and designed for long-lasting performance in the harshest saltwater environments.
Why Choose the Mase IS 13.04?
- 13kW of dependable marine power for yachts, sailboats, and commercial vessels
- Yanmar diesel engine with 1800 RPM for maximum reliability
- Compact, lightweight design for easy installation onboard
- Low vibration and ultra-quiet operation (50 dBA @ 7m)
- Dual shock-absorber system to reduce vibrations and micro-vibrations
- Marine-grade materials designed to resist corrosion and salt exposure
IS Intercooler System
The Mase IS 13.04 uses a dual cooling system with seawater/air and seawater/coolant heat exchangers. This ensures stable generator performance in all environments, independent of ambient temperature. The system also prevents excess heat buildup, extending engine and alternator life.
CBU Control Panel
The advanced CBU Mod-Bus control panel features a modern design with soft-touch buttons and a large display for quick menu navigation. Functions include:
- ON/OFF/START/STOP/MENU operation
- Digital hour-meter, voltage, frequency, and battery monitoring
- Service time countdown and last 10 alarms stored in memory
- 13 distinct alarm icons for quick diagnostics
- RS-485 Mod-Bus connector for integration with boat management systems
Engine – Yanmar Powered
The Mase IS 13.04 generator is powered by the rugged Yanmar 3TNM88F-UGGE diesel engine. It offers easy service access to the feeding system, water pump, and air filter. Built-in safety shutdowns protect against low oil pressure and high exhaust or coolant temperatures.
