HARDIN MARINE
REPLACEMENT 496 & 496HO
Silencer System

This silencer system was specifically designed and tested to comply with the new J-2005 SAE testing standards that are being rigorously implemented on national waterways. The apparent problem that the Mercury 496 & 496HO is an open exhaust configuration that does not comply with the latest noise level limits required by law. This can now be rectified with these direct replacement silencers. In recent testing by “Hot Boat” magazine this system dropped the noise level to a legal 85/86 decibels. Each kit contains one pair of highly polished 316L direct replacement silencer tips plus one pair of external exhaust flappers. Sold in pairs.
