low octane?

[Intruder Runner]

I have an occasional skip in my evinrude!! Can it be low octane gas?

Re: low octane?

Low octane gas is not as likely a culprit as intermittent spark. It could be one plug going bad (arcing) or the coil or the switch box not sending a good signal to the coil. This will probably be hard to trace, unless you're pretty good with electrical stuff (which I am not!).<br /><br />Good luck!

Could be some water in your gas.<br />Only a guess because I've had the same problem<br />(Evinrude also) and it has seemed to clear up considerably after removing water from my tank

Under the water muffs ,try tapping on electrical parts with a plastic handle of a large screw driver.After your engine has run a few minutes at idle ,shut down and inspect plugs to see if they're uniformly wet with gas as you may have a sticking carb.You best get this problem solved as it can lead to a disasterous outcome.You may try a can of carb. cleaner while running

Re: low octane?

If your "skip" becomes more evident and mechanical in nature, suspect the shift dogs in the lower unit. <br /><br />It can manifest itself as if the motor is periodically hitting and object at speed. Enough to make the whole engine jerk once every few seconds when real bad.
