MASE Mariner 710 S 7.1 kW Marine Diesel Generator

Compact 7.1 kW Marine Diesel Power The MASE Mariner 710 S is built for boat owners who need dependable 120/240V AC power without giving up a lot of machinery-space room. It combines a two-cylinder Kubota diesel engine, a brushless synchronous alternator, heat-exchanger cooling and a marine-aluminum sound enclosure in a compact 342 lb package. MASE Mariner 710 S Marine Generator Overview The Mariner 710 S delivers 7.1 kW maximum output and 6.6 kW continuous output at 60 Hz. It is a practical fit for running onboard air conditioning, refrigeration, battery charging, lighting, galley appliances and other AC loads when shore power is unavailable. This is the kind of marine generator that makes sense when access is tight. Routine service points are arranged for easier reach, the engine uses separate coolant and seawater circulation, and the soundproof enclosure is made from lightweight marine aluminum designed to resist harsh onboard conditions. Key Features 7.1 kW maximum / 6.6 kW continuous output at 60 Hz 120/240V single-phase power for common U.S. marine electrical systems Kubota Z482 diesel engine with two cast-iron cylinders Brushless synchronous alternator with Class H insulation Closed-loop freshwater cooling with a seawater heat exchanger CBU EVO IL4 digital control with operating data, alarms and maintenance reminders Marine-aluminum sound enclosure for corrosion resistance and reduced noise 56 dBA at 23 ft under the brochure's 60 Hz test specification Compact service-friendly layout with oil drain pump and accessible maintenance points Double vibration-isolation system to reduce transmitted vibration Best Uses Sportfishing boats and center-console vessels with enclosed machinery space Motor yachts and cruising boats that need quiet overnight AC power Houseboats and liveaboard vessels running refrigeration, lighting and battery chargers Marine air-conditioning support while anchored or away from shore power Commercial and workboats needing a compact auxiliary generator Repower projects where low weight and a small installation footprint matter Control and Protection Functions The CBU EVO IL4 controller provides manual starting and displays AC voltage, frequency, operating hours and starting-battery voltage. It also monitors low oil pressure, high engine temperature, alternator battery-charger failure, frequency and engine-speed protection, maintenance warnings and alarm history. The system includes an emergency-stop button and magneto-thermal circuit protection.

Frequently Asked Questions How much power does the MASE Mariner 710 S produce? At 60 Hz it is rated for 7.1 kW maximum and 6.6 kW continuous output. When sizing, use the continuous rating and account for the starting surge of air conditioners, pumps and compressors. Does it provide both 120V and 240V power? Yes. The 60 Hz version is specified for 120/240V single-phase output at 59.2/29.6 amps. What engine is used? The Mariner 710 S uses a Kubota Z482 two-cylinder, 479 cc diesel engine operating at 3,600 rpm for the 60 Hz configuration. Is this an air-cooled marine generator? The engine uses a closed coolant loop and a seawater heat exchanger, with separate pumps moving coolant and seawater. Airflow cools the alternator. How quiet is it? The manufacturer lists 56 dBA at 23 feet for the 60 Hz model. Installation quality, exhaust routing, compartment construction and nearby surfaces can affect the sound heard onboard. Can it run marine air conditioning? It can support many marine air-conditioning systems when the total running load and compressor-starting demand stay within the generator's capacity. Add the running watts of every simultaneous load and confirm starting requirements before ordering. Are the pictured mufflers, separators and remote controls included? No. Those gallery images show optional accessories identified in the brochure. They are sold separately unless your written quote or order specifically includes them. Does this generator require professional installation? Yes. Marine generator installation involves fuel supply and return, raw-water intake, wet exhaust, electrical protection, battery wiring, ventilation and safe service access. Installation should follow current marine standards and be completed or reviewed by a qualified marine professional. Before You Order Every boat is different. Check available space, service clearances, electrical loads, exhaust routing, seawater plumbing and starting-battery requirements before purchase. If you are replacing an existing marine generator, compare the full installation layout rather than matching only the kW rating.
