I have a 1989 150 Evinrude and i had motor work done to it this past winter. New stator, flywheel and a good carburator cleaning so i thought that it would run fine this year. I have asked some people about why it wont keep running when idling. I have tried sta-bil and I run startron on every fill up. When i put the muffs on to start it at home it will idle all day perfectly but as soon as i get it to the lake it wont idle. It gets pretty flustrating! The motors a two stroke as well. Anything suggestions?

Thanks, Allen.

Have you thought of taking the boat to a service center for a checkup?

It could be a number of things including your fuel line.

The guys on the Forum will give you their input but I suggest having a professional service tech take a look at the engine and correct the problems.

I took my boat in two weeks ago for a check up as I was having a few minor problems and we found the fuel line was eaten up due to the ethonol although I have been using the marine StaBil for years.

Good luck and let us know what you find out as it will help all of us in the future.

If you haven't replaced your fuel lines/bulb/fuel filter in a couple of years, that would be a prime culprit. When was the last time the fuel pump was rebuilt? The diaphragms wear out. Low fuel pressure could cause a slow idle.

I would start with these and see if that helps.
