This might be angling line, too much algae, or some other material that's worked its method around the blades. Very carefully eliminate anything that might be twisted around the prop, and offer it a checkup for any damage that might be present. If the prop is damaged, it needs to be replaced. Particles around the prop is one of the most likely perpetrator if your watercraft motor starts, yet rapidly passes away.
Choke, Throttle, and also Guide Light bulb
Attempt to begin the engine both with as well as without utilizing the choke. If this does not work, attempt changing the throttle setting. Applying basically gas can sometimes do the trick. Ultimately, press the guide light bulb a few times to see to it the engine is primed up.
Battery
Some batteries have an on/off switch. If this holds true for your battery, make sure the switch gets on. After that, if your engine is under 25HP, you might be able to utilize the emergency situation cable to pull-start. It's feasible to do this with as much as a 50HP engine, however realize that the higher the HP, the more difficult this will certainly be. If this works, the battery is likely the problem. You might require to change it.
Reasons Your Mercury Outboard Still Isn't Working
Ok, so you have actually tried the quick solutions, yet you still haven't determined why your Mercury outboard electric motor quit working. The next step is to do a thorough checkup of each system/engine part up until the enigma is solved.
Beginning System
If you hear a clicking sound when you attempt to crank the engine, the starter solenoid might be responsible. Relying on the version, you may have the ability to change only the solenoid, or you may have to change the whole self-contained system. To evaluate the solenoid, adhere to these actions.

Any other accumulation or deposit can be gotten rid of with a combination of water and baking soft drink at a proportion of 1 mug:1 tablespoon, specifically. If you use this mix, be sure to extensively dry out the battery instantly after. Finally, charge the battery and tidy the links. Then, reconnect the positive cord, adhered to by the unfavorable. Use dielectric oil when re-installing the links.
If all is well with the battery, you'll need to check if a fuse has blown. To examine if a fuse has actually blown, utilize a screwdriver to remove the electric cover of the electric motor. With pliers, carefully eliminate the fuse owner. If the facility is broken, that implies it's blown. You'll have to inspect the Mercury outboard repair service guidebook to establish the proper amperage needed to replace it. If none of this works, proceed onto the other systems until the issue is solved.
Gas System
The fuel system is made up of the gas pump, gas filter, check shutoffs, gas tubes, fuel pump diaphragm, as well as injectors. Listen for the operation audio. If you can not listen to the system trying to function, check for connection between the fuse holder, fuse, fuel pump relay, as well as electrical wiring harness. Fixing or change the faulty part(s) if there is no connection. If there is connection, change the electric gas pump.
If you hear the operation audio, check each part of the fuel system separately. Initially, check the gas filters as well as seek obstructions, fractures, twists, or leakages in the hose pipes. Change any type of get rid of damages. Next off, inspect the diaphragm for cracks or other indications of damage. Then, check the vapor separator needle shutoff for bends or indicators of wear. The next action is to check the injectors for blockages and also resistance. Then, check for poor connections.
Finally, note if there is any type of water in the gas. Ethanol gasoline draws in water, which adversely impacts the combustibility of the fuel. This is specifically most likely if you haven't made use of gas ingredients or stabilizers. Water in the gas might additionally cause a bad or failing fuel pump. If you find water in your gas, you might wish to check that the pump remains in good condition.
You can execute a Mercury outboard fuel pump test by eliminating the ignition system wire boot from the spark plug and after that eliminating the ignition system with a plug socket and also wrench.
