Centek Vernatone FRP Wet Muffler — 3-1/2" Round — Above Waterline — 383-1000105

The Centek Vernatone is a fiberglass-reinforced plastic (FRP) wet exhaust muffler built for above-waterline marine installations. Designed for both gasoline and diesel engines, it minimizes added back pressure while delivering reliable exhaust noise reduction — and unlike metal mufflers, it will not rust or corrode in the marine environment.

  • Minimizes added back pressure for engine efficiency
  • Compatible with gasoline and diesel engines
  • 3-1/2" round body profile
  • Above-waterline installation only

Specifications

  • Body style: 3-1/2" Round
  • Installation: Above waterline only
  • Fuel compatibility: Gas and Diesel
  • Material: Fire-retardant FRP
  • Weight: approx. 14 lbs (6.4 kg)

Parts Desk Insights

Best use case: The Vernatone FRP wet muffler is a proven choice for inboard and sterndrive exhaust systems where corrosion resistance and low back pressure are priorities. The 3-1/2" round profile suits mid-size inboard applications — confirm your exhaust hose diameter before ordering to ensure a proper connection. FRP wet mufflers are preferred over rubber or metal alternatives in many custom and repower installations due to their longevity and resistance to heat cycling. Above-waterline installation is required; this muffler is not rated for below-waterline or dry exhaust applications. Contact us if you need help selecting the right Vernatone size for your engine and exhaust system layout.
