Engine and Model Compatibility
This kit is listed for Johnson/Evinrude outboards with a primer valve. It is not listed for the 1993 9.9 HP and 15 HP models, which use a different primer-valve arrangement. Confirm the engine model, year, existing primer-valve configuration, and the numbers on the original components before ordering.
| Brand | Application | Stroke | Exclusion | Replacement references |
|---|---|---|---|---|
| Johnson/Evinrude | Outboards equipped with a primer valve | 2-stroke fuel-system application | 1993 9.9 HP and 15 HP models | 175158, 437228 |
Because primer-valve configurations can vary by model and production year, a general horsepower or year range should not be used as the sole fitment check.

- Relieve fuel-system pressure and disconnect the battery according to the engine manufacturer's service procedure.
- Record the positions of any connected fuel lines before removing the original service-valve components.
- Remove the existing service valve, cover, and gasket assembly, then clean the mounting area without allowing debris to enter the fuel system.
- Install the replacement gasket assembly and service valve with O-ring in the original locations. Tighten fasteners according to the engine manufacturer's specifications; do not overtighten.
- Reconnect the fuel lines and battery, then prime the fuel system.
- Before operating the engine, inspect the replacement assembly and all connections for fuel leaks.
Consult the appropriate factory service information when removing or installing fuel-system components. If the original assembly differs from the kit, do not force the installation.
Troubleshooting and FAQ
Will this kit fit my 1993 15 HP Johnson/Evinrude outboard?
No. The listed application specifically excludes 1993 9.9 HP and 15 HP models. Verify the model year and primer-valve design before ordering.
What components are included?
The kit includes one service valve with O-ring and one cover and gasket assembly. It is sold as a replacement kit for the corresponding primer-valve components, not as a complete carburetor.
Which original part numbers does the kit replace?
The kit is listed as replacing Johnson/Evinrude/OMC references 175158 and 437228. The corresponding aftermarket interchange is Sierra 18-7044.
Is this an OEM part?
No. This is an aftermarket replacement kit. It is intended to replace the listed components when the engine's primer-valve configuration matches the application.
What should I check before ordering?
Check the engine brand, model, year, primer-valve configuration, and the numbers on the original service-valve and cover components. Do not rely on horsepower alone, and note the exclusion for 1993 9.9 HP and 15 HP models.
