I have a 1996 Evinrude Oceanpro that will turn over, but will not idle. I bought it new and it hasn't been used much. Have siphoned old gas, put new gas, changed water filter, cleaned fuel filter, and changed spark plugs and battery. Any suggestions?
I appreciate it!
If it hasn't been used much chances are the old gasoline formed varnish deposits in the carburetors, pumps, filters, etc. A trained tech would have to check out all the engine systems also to make sure that everything was in good shape. Engine temperature is important for a good idle. Be sure to inspect the connections and fuel lines as ethanol in the gasoline could affect them internally.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
Thanks for responding. One thing I shoud add, last time we used the boat, it ran well and at the end of our fishing trip, it started doing this. That was five years ago, and this is the first time I tried running it again, and it is doing exactly the same thing. Will crank, but won't idle.
