Installation Notes

1. Disconnect the fuel supply and relieve residual pressure from the carburetor system.
2. Remove the float bowl retaining screws and carefully lower the bowl from the carburetor body.
3. Clean the mating surfaces on both the bowl and carburetor housing to remove old gasket material, fuel deposits, and debris.
4. Position the new gasket onto the float bowl or carburetor base, aligning all screw holes.
5. Reinstall the float bowl and torque the retaining screws evenly in a crisscross pattern to avoid distortion.
6. Reconnect the fuel supply, check for leaks, and run the engine briefly to confirm proper sealing.

Troubleshooting & FAQ

How do I know if my carburetor bowl gasket needs replacement?

Common signs include fuel seepage around the bowl seam, rough idling, fuel odor, or visible cracks and hardening of the existing gasket. Replace gaskets whenever disassembling the carburetor for cleaning or rebuild.

Can I reuse the old gasket if it looks intact?

No. Gaskets compress and conform to sealing surfaces during use and lose their ability to seal properly once removed. Always install a new gasket when reassembling carburetor components.

Will this gasket fit my 1993 Johnson 115HP?

Primary fitment is for 1994 and later models. Some engines from 1991–1993 may be compatible if they use the 433000 float bowl, but verify your carburetor assembly against the OEM parts diagram before ordering.

What torque specification should I use for the float bowl screws?

Consult your engine's service manual for exact torque values. Typically, carburetor bowl screws require moderate torque applied evenly in a crisscross sequence to prevent gasket distortion and leaks.

Is this gasket compatible with ethanol-blended fuels?

Yes. The heat-resistant and oil-resistant material is formulated to withstand modern ethanol-blend fuels (E10) commonly used in marine engines.

How many gaskets do I need for a V6 engine?

A 60° V6 engine typically has three carburetors, requiring three float bowl gaskets. This listing includes one gasket; order the quantity needed for your complete rebuild.
