Vetus WLOCKLP75 Waterlock LP75 Marine Exhaust Muffler for 75mm Hose, 10.5L

The Vetus WLOCKLP75 LP75 waterlock (also called a water collector or exhaust waterlock muffler) is built for wet marine exhaust systems that use 75 mm (3 inch) inside-diameter exhaust hose. It collects the cooling water in the exhaust line when the engine is switched off, which stops that water from draining back toward the engine. It also reduces exhaust noise.

Key Features:

• Hose size: 75 mm inlet and outlet connections
• Capacity: 10.5 liters (approx. 2.8 gallons)
• Construction: Corrosion-proof synthetic material
• Connections: Fixed (stationary) hose connections
• Mounting: Horizontal installation
• Drain plug: Included so the unit can be emptied for winter storage
• Sound damping: The internal design also works as an efficient muffler
• Dimensions: approx. 530 x 138 x 290 mm (20.9 x 5.4 x 11.4 in)
• Engine rating: Vetus lists the LP75 for engines up to 63 kW (86 hp)

The LP75 suits installations with long exhaust hose runs, because a longer run holds more water and needs a larger waterlock. Vetus exhaust components are made of plastic and are for wet exhaust systems only. Keep exhaust temperature below 70°C (158°F).
