"Hey, would anyone know how to repair a mercury 35 outboard running on one cylender? I was taking out my boat in the spring and I get to full throttle but it seems like the motor is bogging down, Not going to full speed. I replaced the spark plugs and added carb cleaner to the carborator but nothing happened.
I would appreciate it if anyone would be able to help answer my question or if this has happened to anyone. thanks"
 
"KM, systematic troubleshootin

"KM, systematic troubleshooting is in order to determine what is not working.

You could post your serial number so we know what we are working with.

However, you have to determine why that cylinder is not working...

Could be:

No compression
No spark
No gas getting to it

Each will have very different solutions..."
 
"If Possible a spark plug coil

"If Possible a spark plug coil? I know it has good a compression, its getting gas, I am not sure about the spark, because I changed out the plugs."
 
If you have or can borrow a ti

If you have or can borrow a timing light check to see if you are getting spark at each cylinder. If not just swap the coils around and see if the problem moves - easiest way to check the coil.

It could well be the issue...
