|Aqua Power Ltd Clamp-On Silencers|
Our clamp-on silencers quiet harsh noises produced by high horsepower marine engines very well. The most exciting feature is that no power is lost in most installations which makes it an ideal marine racing muffler.
The Clamp-on silencer is a compact and light weight version of our product. High power models are frequently used on supercharged engines up to 1550 horsepower.
Installation is straight forward: slide it onto the pipe and clamp it in place.
Exhaust systems using through transom tailpipes that dump all the water into the exhaust stream at the very end of the pipe, such as Stellings and CMI, typically have noise reductions up to 3 db greater than the ratings shown below.
All models accept 4 inch external rubber flaps for surge protection.
To select a clamp-on silencer begin by determining your engine
power and restrict your selection to power ranges that include your engine. Next
determine the outer diameter of your tail pipes. Determine what type of tail pipes
you have, standard or stellings. The outer tube of a standard tail pipe extends
to or beyond the inner tube. The inner tube of a stellings tail pipe extends farther
back than the outer tube by as much as 3/4". If your boat has a swimboard or other
obstructions near the tail pipes you may need to determine if the outside diameter
of the silencer will interfere. Also determine if the extension length of the silencer
is acceptable. If you know the decibel level of your engine with open exhaust you can
subtract the noise reduction to determine the approximate final noise level with
silencers installed. Adding external rubber flaps sometimes reduces the noise level
by another two db. All that is left is to read the part number. Your selection should
be verified by our sales department when placing an order.
