Review OMC Evinrude Johnson Petcock

The OMC (Outboard Marine Corporation) 986040 0986040 Evinrude Johnson petcock is an essential fuel system component designed for use with Evinrude Johnson outboard engines. This petcock, also known as a fuel selector valve, allows the operator to select between the primary and secondary fuel tanks, providing the flexibility to use multiple fuel tanks while ensuring reliable fuel delivery to the engine.

The petcock is constructed from high-quality materials, including a durable brass body and a diaphragm made of natural rubber. The brass body is resistant to corrosion and wear, ensuring long-lasting performance even in harsh marine environments. The diaphragm, on the other hand, is flexible and able to withstand the pressure changes that occur when switching between fuel tanks.

The petcock features a simple and intuitive design, with a lever that can be easily operated by the engine operator. When the lever is in the "PRIM" position, fuel is supplied from the primary fuel tank. When the lever is moved to the "SEC" position, fuel is supplied from the secondary fuel tank. The petcock also includes a "CLOSED" position, which can be used to prevent fuel flow when the engine is not in use.

The OMC 986040 0986040 Evinrude Johnson petcock is an important accessory for any outboard engine setup that utilizes multiple fuel tanks. It provides the operator with the ability to switch between tanks, ensuring that they always have a full supply of fuel available, and helps prevent fuel starvation issues that can occur when relying on a single tank.

This fuel selector valve is easy to install, with a simple bolt-on design that allows it to be quickly attached to the engine's fuel system. It is also compatible with a wide range of Evinrude Johnson outboard engines, making it a versatile and valuable addition to any marine setup.

In summary, the OMC 986040 0986040 Evinrude Johnson petcock is a high-quality, durable fuel selector valve designed for use with Evinrude Johnson outboard engines.
