1998 Evinrude Oceanpro 150HP (carbuerated, not a Ficht)
Here is the story on Saturday:
Get to the ramp, prime the bulb, engine cranks right up without even having to choke. It is running great (it does not smoke, it does not sputter while idling, sounding really nice). I ran across the bay for about 20 minutes to get the engine nice and hot. I turned the boat off for a few seconds and it started up right away. I did that several times since this has been an ongoing problem and I wanted to make sure it was starting. So I continued to run across the bay for another 20 minutes or so and anchored the boat. After about 20 minutes I turned the key and the motor started right up. So I was thinking that my problem was solved...not so much. After the boat sat for about 2 hours we attempted to leave. Tried to crank the boat and it did not start. After some troubleshooting we determined that there was NO spark on the plugs at all. I did not have a wrench on me (it went for a swim the last time) but I am willing to bet that the plugs were fouled as well.
Now here is the kicker...This has been an ongoing problem. I have a new OIS sensor, new Stator, adjusted timing, clean carbs, new ignition switch.
Does anyone have any ideas? If it were just a spark issue, my mechanic thinks it has to be the killswitch. However, if it is fouling there may be other issues. I really think the amount of time it sits has a major part in the problem. What would be causing my sparks to foul so bad after sitting an extended period of time.
Dont forget...it runs awesome when it does start, no issues. not lean, not rich, etc.
