MGP waterlock

The MG series of waterlocks are designed for modern high-performance boats with large engines which leave little space to spare in the engine room. The outlet connection at the top can rotate through 360° and the inlet connection is at an angle of 45° upwards

MG waterlocks can only be installed in water-injected exhaust systems. The body is entirely constructed from synthetic materials and is therefore not susceptible to corrosion or galvanic action. They have excellent sound-reducing qualities. 

A drain plug is provided for draining water from the waterlock during winter.
