johnson outboard problem
 

I have a johnson 115 that will not get up to the max rpm the throttle is wide open however it only runs about 2300 rpm instead of 5500-6000. It was running fine, but has sat for about 4 months. Can anyone give me some suggestions ???

Re: johnson outboard problem
 

compression check....then a spark check.. then come back and let us know the results...then fuel checks last....sitting for 4 months could prob mean fuel probs.

you can buy a compression checker $30 and a spark checker $10 at autozone.

His johnson won't get up ;D

Sorry, follow the advice above.

I'll add, how old is the fuel?

Was it stored with fuel stabilizer? How does it idle? When you can't get up your JOHNSON ;D, what exactly does it do?(runs rough, surges, chokes, spits swallows)

The compresion check is fine, the spark check is fine. The fuel was just replaced when we replaced the tank last week. The fuel is flowing fine.

It seems to be limited to 2300 rpm it will jump a little like it wants to get up to speed, but it doesn't.

I do have another question. water is coming out of the hole where the thermostat purges and it is constant. I think the thermostat is stuck. Here is my question, is there a sensor that would limit it from running WOT if it thinks it is overheating.
