Underwater Exhaust

Vertical and horizontal underwater exhaust mufflers provide the best sound attenuation and exhaust reduction by discharging below the hull. At idle speeds a small bypass is used to vent to atmosphere to reduce engine backpressure. All underwater exhaust mufflers are provided with a white gel coat finish and are equipped with stainless crush sleeves inside the inlets and outlets. For installations where the engine is above the waterline only.
