Livorsi Raw Water Flow System

Livorsi Water Flow Gauge

Safe guard your cooling system from costly damage with Livorsi’s Raw Water Flow System The Raw Water Flow system is a new patented system that indicates your engine’s water flow volume. This system warns you of a potential problem or danger that would otherwise not be indicated by a water pressure gauge alone, thus preventing cosmetic and structural damage to expensive exhaust headers, intercoolers and cooling systems. What is Water Flow? Water flow is a real indication of water surging through a cooling system such as: exhaust headers, sea strainers, impellers, Gen sets, intercoolers and any other marine or industrial applications that utilize water flow.   Why You Need It.   Don’t confuse water flow with water pressure; as many OEM engine manufacturers measure water pressure in different areas of the motor. This number may not be telling you the real story of water flow. Your water pressure can be constant from the first day you bought your new boat. The danger may be lurking in the water flow which could be caused by: A plugged heat exchanger extensive debris build-up in the intercooler or sea strainer a kinked hose worn impeller water pickups not collecting enough water for cooling system These may be the culprits causing the good water pressure reading, when in actuality there is poor water flow


Japanese TSL a Reality

Long discussed as the embodiment of next-generation marine technology, the Japanese "Techno-Superliner" (TSL) is now a reality. The 14,500 grt TSL will be built from aluminum and measure 460 x 98 ft. (140 x 29.8 m). To be built by Mitsui Engineering and Shipbuilding's Tamano works for delivery in 2005, the TSL will be propelled to a service speed of 38 knots via a pair of Rolls-Royce Kamewa VLW J235 waterjets, which will absorb 27 MW of power


Rolls-Royce Launches New Waterjet

The largest waterjet so far in the Rolls-Royce Kamewa FF series has now been introduced. It extends the power range of these axial flow aluminium waterjets to 1,800 kW. “As a rough guide, a boat with a twin FF600 installation would have an all-up weight including equipment and fuel of about 60 tons for optimum performance,” said Tomas Renlund, director of the aluminium waterjet business. “But since we tailor the impeller to suit the application and can customise this type of jet to a


BRP $10m Contract for Evinrude Engines

BRP has been awarded a $10m contract from the United States Marine Corps (USMC) for its Evinrude multi-fuel engines (MFE).

Auxiliary power will be provided by two Cummins 6B5. 9GM-powered 50 Kw gensets. Cargo capacity on the vessel's 105 x 24 ft. (32 x 7


USCG Issues Safety Alert

The U.S. Coast Guard issued a Safety Alert stating that a chemical tanker recently suffered a tank explosion in the Gulf of Mexico near Galveston. After stripping a tank, the tankerman opened the tank top cover and an explosion ensued, injuring the tankerman and damaging the vessel. While the investigation is ongoing, the cause appears to be that the bearings in the cargo pump failed, allowing the shaft and impeller to shift and spin against the casing
