Watersports is no easy thing and when you are using the boats with engines for fishing, you will need to be particularly careful about all the aspects of the engine that they are working precisely as they should so you will be getting the right fishing experience. Outboard motors are used for effective speed, efficient power, and better handling on all the different sorts of small boats since they allow better steering power on the motor at the same time while directing the thrust to any direction that you might be looking to make it work.

All that is certainly great and you enjoy the experience a lot certainly. Yet, outboards have an oil injection system in them that should be working correctly. If that is not working, there are some common issues that you will have to face and your boating experience will be ruined. A few ways for you to check if the oil injection is working on the outboard are:

How To Tell If Oil Injection Is Working On Outboard

1. Stuttering

The first thing that you will notice if the oil injection system is failing is the stuttering and missing on your outboard engine. That is pretty obvious to know if you are facing these misfires and power loss issues on the outboard engine. However, there can be some other problems that can cause you to have the same issue.

That is why it doesn’t mean with certainty that your oil injection is not working properly. Yet, if you are facing the problem, you will need to ensure that you are checking on all such problems at the same time including the oil injection system and you will be able to solve the problem that is causing you to face such inconvenience.

2. Fuel Pressure Gauge

Another common method that you can use to ensure that your oil injection on the outboard is working is to use a fuel pressure gauge. To do that, you need the appropriate fuel pressure gauge, and then you will need to connect it to the fuel pipe of your outboard. Once you have that done, you need to crank the engine a few times.

That should be helping you out optimally to get the reading at which your fuel pump is pumping the oil. The optimal reading for a normal fuel pump should be between five to seven and if it is below that, it means there might be something wrong with the fuel pump or the injectors.

Be mindful that the pressure rating might not be the same for all and you will need to be particularly careful about that to ensure that you are checking the optimal fuel pump pressure by consulting the OEM or owners’ manual for the outboard that you are using on your boat.

3. Check Injectors

Lastly, if you are unable to figure out the issue and you want to know if your injectors are working properly on the outboard that you are using, you will need to ensure that you are getting them checked properly. It is pretty simple and all you will need to do is to ensure that you are disassembling the injectors properly and then installing them on an injector testing tool.

There are multiple injectors testing tools out there that will engage these injectors for you and with that, you get to enjoy the right edge of perfection and check the condition of your oil injectors at the same time. So, you can check if your injectors are working efficiently with those injector testing machines and you will be certain about it. Yet, there is one more thing to be mindful of and that is the current on your injectors.

The injector testing machine only tells you about the mechanical working of the injectors and they might be failing due to loss of current. So, you will also need to check on the cables that are connected with your oil injectors on the outboard and ensure that they are getting the right amount of current and signals from the engine that is required for the oil injectors to work. That should be helping you out properly to figure out if your oil injectors are working in the right manner.
