My 120hp evinrude 1993 stop when i cruise at low speed

Also i remark that only one spark plug is dirty. Is that possible that it is a problem with oil injection. My mechanic tuned up the carburators but the problem is still there.

There always that possibility and if the injectors are identical you could switch them and see if the problem moves. Then you know its that one injector. The other possiblity is spark. The wire or the coil for that plug could be weak.

It reads codes po300 po300 po522 but it runs perfect sometimes I need to press fuel pedal to start?

code p 0300 refers to random/multiple cylinder misfires detected ===causes spark plugs ---HT leads ---injector/s--ignition coil/s---low compression---wiring
code p 0522 refers to engine oil pressure sensor/switch--low voltage ===causes wiring short to ground ---engine oil pressure sensor /switch---ECM
for the first code having to alter the accelerator position ( which tells the ECM to let in more fuel indicates either a low pressure in the fuel manifold or that the injectors need cleaning
At high way speeds when the engine appears to be running good , it is still possible to have random misfires caused by low fuel pressures and /or dirty injector tips
It would be a good idea to check the oil pressure with a mechanical gauge ,then replace the oil pressure sensor/switch

Evinrude 120hp v4 hi i have a lot of fule going into the motor it always floods and wont fire how do i know if the fule pump is stuffed

This isn't a networking problem.

But I will take a shot at it. Make sure that it is a flooding problem and not a lack of spark.

You should be able to figure both of these things out by removing a spark plug, if its flooded there will be excess of fuel in the cylinder at which point you want to check that the carb and carb float is working correctly, if its a lack of spark you may need a new rectifier.

My 1993 seville was running fine, I turned it off and when I tried to start it again the starter kicked but the engine would not turn over as if it's stuck or locked.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

I have a '83 Honda Nighthawk that I'm having oil light problems with. Once the engine gets warmed up, usually after about 10 minutes of riding, and I come to a stop sign/light the oil light comes...

If your oil pressure light is coming, you probably have low oil pressure caused by worn engine parts. Usually low oil pressure is observed when you are idling since the pump is pumping slowly. When you raise RPM's, the pump speeds up and pressure increases. Take the bike to someone who can diagnose it properly, but it sounds like it is time for some repairs.

check your transmission fluid levels they may be low, and replace the spark plugs you know give it a good tune up! wires, air filter, fluids, clean throttle body, IAC sensor, check for Vacuum leaks; like cracked hoses that lead to your map sensor or EGR valve etc.

Missing operators manual for Evinrude 2 hp outboard motor

Your best bet is ebay for a replacement user manual. Take a look around, you will come across one... For the meantime, gas oil ratio should be 50 parts gas to 1 part oil, i.e. 50:1. General care: Dont go full throttle for any length of time. Cruise of 3/4 throttle... Always flush engine after use in saltwater, including washing down exterior. Keep spark plugs in good order and check prop for fishing line wrapped around in near the prop hub. Otherwise, get a yearly service and have them check the water pump and replace as needed, get it tuned etc and gearbox oil changed.
