Johnson Outboard Motor Repair - Motor Parts For Old Johnson And A Boat Motor

When it comes to Johnson outboard motor repair you can expect similar problems to all the gasoline-powered motors on the market. The only thing different is the fact that they are going to happen less often because Johnson motors are really good when talking about quality. If you notice problems the best thing you can do is to try and fix it yourself in order to avoid paying for something that might be really easy to fix. Contrary to what you might believe, Johnson outboard motor repair is not as complicated as you think. All that is really needed is the manual and properly understanding how engines run. All Johnson motors need 3 elements in order to properly run: fire, fuel and compression. If these elements are not synchronized the engine is not going to work well.

The first thing that you need to do is check for some simple problems that might make your old Johnson boat motor run poorly. If it is not starting then look at spark plug wires as they might be loose. If one wire is not properly connected then the engine is not going to fire. You will also need to look at cables that are attached to the battery. In a similar fashion, if they are not properly connected the motor is not going to work at a full capacity. The good news is that such problems are really cheap to fix.

We also need to analyze the fuel pump. There are many Johnson outboard motor repair problems that are linked to it. It is really easy to make a mistake and believe that a fuel problem is an ignition problem. The boat motor runs on fuel so if you use contaminated or bad fuel you will have a motor that is never going to properly run. In the event that fire reaches all cylinders and we have good compression the problem is usually in the fuel used. There are different factors that can cause fuel problems. This includes bad gas, bad fuel pumps, clogged carbs, loose fuel lines or a fuel tank that is not venting properly. Check out all of the problems before you are going to purchase a new part.

We recommend that you also troubleshoot ignition. Unfortunately in this case there might be a need to ask for professional help. You will need to check timing in order to make sure that you have full functioning. Most problems are going to be linked with broken bare wires or something that is shorted out. When we are faced with a serious problem you will need to take the motor to licensed technicians.

Sometimes you will have to run compression tests. This is done in order to see if there are internal problems in the engine. It is common to notice stuck rings that appear because of carbon buildups or damaged cylinders. Leakdown tests on cylinders are also required in order to notice if there is leakage that appears due to damaged, stuck or wore rings. If you are faced with a leakdown that is higher than 15 pounds on a cylinder then you need to stop using the boat motor and fix the situations. More problems are going to appear in the event that you keep using the engine.

If you have a model that uses an oil mix you need to make sure that the right mix is always used. If this is not happening then the internal engine workings are going to be affected. Then analyze the cooling system. The boat’s engine will be destroyed really fast if there are some overheating moments. We recommend replacing water pump impellers twice every year. Also, keep in mind that impellers can rot so you should make sure that the engine is used as non-use is even worse than abuse.

In the event that you went through all the facts mentioned above and you still cannot fix the engine we recommend that you go to a licensed Johnson outboard motor repair shop. Trying anything else would only produce more damage unless you really know what you are doing. Even if you will end up paying more than it would cost if the repairs would be done by you, it is still better than risking ruining the engine.

To sum up, Johnson outboard motor repair is not difficult but you have to really know what you are doing. We recommend that you start with the troubleshooting section in your manual and then focus on what was written above. If nothing can be done it is always better to ask for professional help. Also, it is highly recommended to pay attention to always use proper maintenance methods so that the motor will last longer. Johnson outboard motors are really good and they have a really long life span in the event that you properly take care of them.
