Bottomless Muffler

UNDERWATER DISCHARGE APPLICATIONS

 

 -Muffler Sound Quality: Normal tone conversation can easily be heard over engine exhaust sound.

- Application: Engine room/Hull side positioning.

-Very compact – Very quiet.

-Accepts a wide variety of exhaust system configurations.

-Inlet(s) on Muffler are positioned per application requirements.

-Surge resistant.

-The bottom of muffler must be below the water line.

-Material: biaxial E-Glass/Vinylester, fire-retardant (Class 1) Hetron Fr 998 resin.

-Can be flanged on bottom for ease of installation.

-Molded Gelcoat Finish color: High gloss bright white. “Show Finish” quality finish available upon request.

-Weight: Light for size – muffler specific.

-316L Stainless Steel crush resistant rings installed at all muffler hose connections.

 

 EXHAUST THRU HULL DIFFUSER

-Purpose: A pre-designed shape that will provide proper exhaust ejection without flow restriction.

-Material: Biaxial E-Glass/Vinylester, fire-retardant (Class 1) Hetron FR 992 resin.

-Thickness: Approximately 5/32” thick.

-Shape is easily inserted into bottom of hull, then laminated to desired thickness.

  

UNDERWATER DISCHARGE COWLS

-Directs exhaust gas across hull bottom.

-Proprietary design facilitates exhaust discharging  to chine, preventing exhaust gas from entering into propellers / propeller tunnels (eliminates exhaust related cavitation)

-Allows smooth exhaust gas exit.

-Promotes exhaust gas flow disintegration.

-Promotes thin layer gas turbulence which remains close to hull bottom.

-Material: Biaxial E-Glass/Vinylester, fire-retardant (Class 1) Hetron FR 992 resin.
