Waterlocks &mufflers Exhaust system with the water injection point “C” less than 15 cm above the waterline. Exhaust system with the water injection point “C” 15 cm or more above the waterline. Waterlock/mufflers type NLP (Ø40-45-50-60-75-90mm) How these waterlocks operate The NLP waterlocks are of dual stage construction, featuring upper and lower chambers with a horizontal partition plate and a riser tube through the centre. Compared with single stage waterlocks using only one chamber, these NLP waterlocks offer superior silencing of exhaust noise with minimal back pressure. Since the top chamber may be rotated through 360° and both the inlet and the outlet connectors can rotate through 360°, installation of the exhaust assembly even in confined engine spaces is greatly simplified. The rotatable inlet of the waterlock is connected to the engine exhaust manifold, using Vetus exhaust hose . The exhaust gases, mixed with cooling water are forced from the lower chamber into the upper one, via the central riser tube and then through the (also rotatable) outlet connector at the top. This outlet connector is coupled to the transom connector, again by means of Vetus exhaust hose. For optimum silencing of exhaust noise, we recommend installation of a Vetus muffler and gooseneck NLPG in the exhaust line, after the NLP waterlock. To calculate the required waterlock capacity, use the following formula. D = Internal diameter of the hose (mm) L = Length of hose (mm) The right combination of engine and waterlock ensures optimum sound attenuation. This table shows the optimal combinations. (Calculated with a back pressure of 0.1 bar) when the engine manufacturer allows a higher back pressure, Vetus waterlocks are suitable for engines with a higher output than indicated in this table Calculation example Choose your exhaust system mm Exhaust (mm) Type: LP, MF, NLP, LSS, LSL Type: MV Type: MGP, MGS, MGL, LSG 30 30 13.6 hp / 10 kW - - 40 40 24.5 hp / 18 kW - - 45 45 30 hp / 22 kW - - 51 51 38 hp / 28 kW - - 60 60 53 hp / 39 kW - 46 hp / 34 kW 76 76 86 hp / 63 kW - 75 hp / 55 kW 90 90 121 hp / 89 kW 141 hp / 103 kW 105 hp / 77 kW 102 102 155 hp / 114 kW 181 hp / 133 kW 136 hp / 100 kW 102 127 - - 173 hp / 127 kW 127 127 241 hp / 177 kW 281 hp / 206 kW 211 hp / 155 kW 127 152 - - 256 hp / 188 kW 152 152 345 hp / 254 kW 403 hp / 296 kW 302 hp / 222 kW 152 203 - - 420 hp / 308 kW 203 203 - - 539 hp / 396 kW 203 254 - - 691 hp / 508 kW 02 131 Engine room
