Quicksilver Marine Engine Troubleshooting Tips


Occasionally, your computer may display an error code indicating that a Mercury marine engine is being serviced. This problem can have several causes.

Why is my outboard turning over but not starting?

If they checked the battery disconnect and charged the batteries, but your engine still won’t start, check the battery cables. Make sure the spoilers between the engine and the battery are free from corrosion. Reconnect or replace any assembly cables that may be damaged.

Outboard motors are notorious for their problems. To troubleshoot an engine, you perform a series of checks related to specific problems that arise and fix them as needed. The most common problem with two-stroke and four-stroke engines starts with the fuel system.

Mercury Marine of Wisconsin has been manufacturing two-stroke and four-stroke outboard motors from 2.5 to 300 horsepower for over 75 years. engines. If the person has a two-stroke engine, your outboard will need to add oil to the oil to lubricate the engine. Four-stroke locomotives do not need oil in this engine and are much cleaner overall.

Fuel Mixture

All two-stroke magneto engines require the addition of the selected oil to the gasoline. The ratio of oil and fuel depends on the preferences of a particular engine. The gel protects and lubricates the engine for long-term well-being. If you don’t mix the oil in the correct ratio, which can be 32:1, 40:1 plus 50:1 dependingbridges from your locomotive engine, you will have problems such as:

To fix this, clean the fuel tank of vegetable oil. Pour the correct amount of oil into the container with the indicated gallon of gasoline. For example, if you need a 32:1 cut, each gallon of gasoline requires three ounces of proper motor oil to mix. For a 40:1 ratio, add 3.2 ounces of additive and oil for a 50:1 ratio, equaling 2.6 ounces of oil for every gallon of gasoline.

How do you know if your outboard motor is bad?

Be quiet. During a test drive to start the engine, you should hear the sound of the fuel pump starting.Slow down, stop or stutter.a sip of gas.Heat.one way valves.Membrane.fuel stabilizers.

Remove and clean the spark plug and replace it before pouring gasoline directly into the fuel tank. Improperly mixed garbage gas also tends to foul the spark plug.

Power Failure And Excessive Vibration

Check tank ventilation and hoses.Check fuel connection.Check fuel filter/water separator.Check/replace secondary fuel filter.Check/replace air filter.Check spark plugs/ignition.Pcheck/clean the carburetor.

Outboard motors need this because you run them and fill them with gas until they stop working on their own. When the core is idle, it is undoubtedly hot enough to keep running. A stall, power failure, or excessive vibration usually indicates one or more of the following, depending on the situation. problem:

If the propeller is dirty, turn off all engines and remove the blades from the propeller. But if its motor is running fine but the pontoon isn’t moving anywhere, it’s likely that the propeller isn’t spinning because the best shear pin has broken. The pin is definitely designed to break in place of the corresponding propeller if it comes into contact with chips or a stationary object.

If the propeller is working normally, but the outboard locomotive engine vibrates or vibrates heavily, this may be due to a damaged or shared propeller. Make sure the blades don’t squeak or break; Replace damaged productsPellers are new.

Outboard generators draw water from a lagoon or river ocean through a chute to prevent engine fires. Dirt in the water can get stuck in the intake tract and cause the engine to overheat. Check the input for a blockage. Other possible causes of overheating are:
