How to Bypass a V-RO Pump on a Johnson Outboard Motor

The V-RO pump is a vital part of your Johnson outboard motor. It provides the fuel that the engine needs to run. However, there may be times when you need to bypass the V-RO pump. This could be due to a problem with the pump itself, or it could be because you need to perform maintenance on the engine.

Bypassing the V-RO pump is a relatively simple process, but it is important to follow the steps carefully. If you do not bypass the pump correctly, you could damage your engine.

In this article, we will show you how to bypass a V-RO pump on a Johnson outboard motor. We will provide step-by-step instructions, along with pictures and diagrams. We will also discuss the reasons why you might need to bypass the pump, and the potential risks involved.

So, if you need to bypass the V-RO pump on your Johnson outboard motor, read on for all the information you need.

Step Action Explanation
1 Turn off the engine This will stop the flow of fuel to the VRO pump.
2 Locate the VRO pump The VRO pump is usually located on the engine block.
3 Disconnect the fuel line from the VRO pump This will stop the flow of fuel to the VRO pump.
4 Start the engine The engine will now run on the main fuel pump.
5 Reconnect the fuel line to the VRO pump This will restore the flow of fuel to the VRO pump.

The Vro pump on a Johnson outboard motor is a variable-ratio oil pump that supplies oil to the engine at a rate that is proportional to the engine speed. This helps to ensure that the engine receives the correct amount of oil, regardless of the engine speed.

However, there may be times when you need to bypass the Vro pump. For example, if the Vro pump fails, you will need to bypass it in order to continue operating the engine.

Bypassing the Vro pump is a relatively simple procedure, but it is important to follow the steps carefully in order to avoid damaging the engine.

Step 1: Disconnect the Vro Pump

The first step is to disconnect the Vro pump from the engine. To do this, you will need to:

1. Locate the Vro pump on the engine. The Vro pump is typically located on the front of the engine, near the water intake.
2. Disconnect the electrical connector from the pump. The electrical connector is a small, black connector that is typically located on the top of the pump.
3. Disconnect the fuel line from the pump. The fuel line is a small, black hose that is typically connected to the bottom of the pump.

Step 2: Install a Bypass Valve

The next step is to install a bypass valve in the fuel line between the tank and the Vro pump. To do this, you will need to:

1. Install a bypass valve in the fuel line. The bypass valve is a small, plastic valve that is typically available at your local auto parts store.
2. Make sure the bypass valve is open. The bypass valve should be open so that fuel can flow directly from the tank to the engine.

By following these steps, you can safely bypass the Vro pump on your Johnson outboard motor. This will allow you to continue operating the engine even if the Vro pump fails.

Additional Tips

  • If you are not familiar with working on engines, it is best to have a qualified technician perform this procedure.
  • Make sure to use the correct type of bypass valve for your engine.
  • Be careful not to damage the fuel line or the Vro pump when installing the bypass valve.
  • Inspect the bypass valve regularly to make sure it is working properly.

Step 1: Disconnect the Electrical Connector

The first step is to disconnect the electrical connector from the Vro pump. This is usually a small, black connector located near the pump. To disconnect the connector, simply grasp the two tabs on either side of the connector and pull them apart.

Step 2: Disconnect the Fuel Line

The next step is to disconnect the fuel line from the Vro pump. The fuel line is usually a small, black hose located near the pump. To disconnect the fuel line, simply grasp the hose and pull it off of the pump.

Step 3: Start the Engine

Once the electrical connector and fuel line have been disconnected, you can start the engine. To start the engine, turn the key to the “On” position and press the starter button. The engine should start and run normally.

Step 4: Reattach the Vro Pump

Once the engine is running smoothly, you can reattach the Vro pump. To reattach the pump, simply reconnect the electrical connector and the fuel line.

By following these steps, you can bypass the Vro pump on your Johnson outboard motor. This can be a helpful troubleshooting step if you are having problems with your engine. However, it is important to note that bypassing the Vro pump can void your warranty. Be sure to consult your owner’s manual for specific instructions before bypassing the Vro pump.

How do I bypass a Vro pump on a Johnson outboard?

1. Turn off the engine.
2. Locate the Vro pump. It is typically located on the side of the engine, near the water intake.
3. Disconnect the fuel line from the Vro pump.
4. Connect a short piece of fuel line between the fuel tank and the engine.
5. Start the engine and check for leaks.
6. Reattach the fuel line to the Vro pump.

What are the benefits of bypassing a Vro pump?

  • Increased fuel efficiency. Bypassing the Vro pump eliminates the need for a fuel pump, which can save fuel.
  • Reduced maintenance costs. A Vro pump is a complex component that can be expensive to repair or replace. Bypassing the Vro pump eliminates the need for maintenance.
  • Simplified troubleshooting. If the engine is having problems, bypassing the Vro pump can help to isolate the problem.

What are the risks of bypassing a Vro pump?

  • Engine damage. If the engine is not getting enough fuel, it can overheat and damage the engine.
  • Fuel leaks. If the fuel line is not properly connected, it can leak fuel, which can be dangerous.
  • Fire hazard. A fuel leak can create a fire hazard.

When should I bypass a Vro pump?

You should only bypass a Vro pump if you are confident that you can do so safely. If you are not sure how to bypass a Vro pump, you should take your boat to a qualified mechanic.

What are the steps to troubleshoot a Vro pump?

1. Check the fuel line for leaks. Look for any cracks or damage to the fuel line. If you find a leak, repair or replace the fuel line.
2. Check the fuel filter. Remove the fuel filter and inspect it for dirt or debris. If the fuel filter is dirty, clean or replace it.
3. Check the Vro pump. Turn on the engine and listen for the Vro pump. If you do not hear the Vro pump, the pump may be defective.
4. Test the Vro pump. Disconnect the fuel line from the Vro pump and connect a fuel line to a test gauge. Start the engine and check the fuel pressure. If the fuel pressure is low, the Vro pump may be defective.

What are the symptoms of a bad Vro pump?

  • The engine may not start or run smoothly.
  • The engine may lose power.
  • The engine may overheat.
  • The engine may smoke.
  • The engine may make strange noises.

    bypassing a Vro pump on a Johnson outboard motor is a relatively simple process that can be completed in a few minutes.
