Waterlock/Silencer - 40/45/50mm 333249

Combination waterlock and muffler manufactured from high density polyethylene to suit engines up to 50HP. These waterlocks are suitable for wet exhaust systems with hose diameters of 40mm, 45mm or 50mm. Simply trim off the stepped tails to the required size and connect the hose with double exhaust clamps as is normal recommended practice of installation for small craft. Depending on the relative height of the waterline, care must be taken to prevent water back-siphoning into the engine by installing a gooseneck and syphon break.
