Centek Marine Vernalift Side In, Top Out Wet Exhaust Muffler 1500025
The Centek 1500025 Vernalift is a compact fiberglass wet-exhaust lift muffler for marine propulsion engines and generators. Its 2-inch side inlet and 2-inch top outlet help reduce exhaust noise while collecting and lifting cooling water through the wet-exhaust system. Centek identifies this model for gasoline and diesel applications and states that it meets or exceeds ABYC P-1 requirements.
Compatible Applications
- Marine inboard propulsion engines using 2-inch exhaust hose
- Sailboat auxiliary engines where the side-in, top-out configuration suits the installation
- Marine generators with compatible 2-inch wet-exhaust connections
- Gasoline or diesel marine exhaust systems
- Applicable installations with the engine or generator above or below the waterline
Confirm the engine manufacturer's exhaust-hose specification, required water-lift capacity, and installation geometry before ordering.

Installation and Fitment
Use the side inlet for the engine's wet exhaust and route the top outlet toward the vessel's exhaust discharge. Verify the 2-inch inlet and outlet hose sizes, side-in/top-out orientation, mounting footprint, available height, exhaust back-pressure requirements, water-lift capacity, hose routing, rise, and siphon protection before installation. Support the muffler independently rather than using the exhaust hose as its primary support.
Technical FAQ
Can this muffler be used with gasoline and diesel engines?
Yes. Centek identifies the Vernalift for both gasoline and diesel marine applications, subject to correct system design and fitment.
Is this model suitable for a marine generator?
Yes. It is identified for generator installations when the generator's exhaust specifications and the muffler's dimensions and connections match.
Will every 2-inch Vernalift fit the same installation?
No. Centek offers several 2-inch Vernalift models with different body sizes and capacities. Match the existing footprint, height, orientation, hose connections, and water-lift requirements.
Can it be installed above or below the waterline?
Centek identifies the Vernalift for applicable installations above or below the waterline. The complete exhaust layout must still follow the engine manufacturer's requirements and applicable marine-installation standards.

Parts Desk Insights
Best use: Choose this compact side-in/top-out Vernalift when a marine propulsion engine or generator needs a 2-inch wet-exhaust lift muffler and the available footprint matches the approximately 6.38-inch body diameter, 6.14-inch height, and 7-inch square base.
Common mistake: Matching only the 2-inch hose size. A different Vernalift body may have a different water-holding capacity, mounting footprint, or outlet geometry.
Sizing and fitment: Confirm both hose connections, orientation, dimensions, exhaust back pressure, water-lift capacity, and the engine manufacturer's exhaust requirements before replacing the existing muffler.
