Waterlock Mufflers - LSG & LSS Series, 4.5 Gal 90mm (3-1/2")I/O, 22-3/4" L x 6-11/16" W x 14-1/2" H

Sometimes, notably in the case of sailboats, the exhaust hose is so long that an extra large waterlock is needed to prevent the large volume of water in the line from running back into the engine once it has been stopped. The LSG and LSS mufflers provide the extra capacity to help keep your engine safe. At a mere 8-7/8" high, the LSS models are well-suited for shallow bilges.
• Ideal solution for boats sailing in rough waters, without the engine running
• Both inlet and outlet ports rotate through 360° for ease of installation in tight bilges
• Synthetic material - completely corrosion-proof
• Fitted with a drain plug for winter storage
• LSS - internal baffle; includes (1) securing strap
• LSG - internal inlet check valve; multiple baffles; includes (2) securing straps; option for exhaust temp. sensor
