Evinrude 200 hp over rev when fogging

[riddlewa]

In December I encountered a problem while winterizing my 2001 200hp Eninrude. I was running the engine just out of neutral to speed up the flow of the fuel/stablizer mixture into the engine. After 15 min's of this, I decided to go ahead and fog the engine. Bad idea. The engine over reved and the EMM (internal computer board) killed the engine before I could jump in the boat and do it. <br /><br />Evinrude tech says everything should be fine, just need to clear the error code from the EMM. Anyone ever seen this before? <br /><br />Keeping my fingers there is no real problem. Evinrude dealer has it in line at the shop. Should know something definite in the next week or two. <br /><br />Any info appreciated. <br /><br />Thanks <br />Allen <br />Guitar Picker <br />

Re: Evinrude 200 hp over rev when fogging

Yup, they do that. The best way to minimize the run away (over rev) situation is to run the engine in a tank (or big barrel) of water, this puts some back pressure on the exhaust system and will minimize the chance for a run away.<br /><br />Personally, I always spray the fogging oil into the engine from iside the boat and I tie a piece of string to the emergency stop lanyard and run it to the back of the boat. In the event of a run away, all I have to do is reach down and pull the string. I've had it happen a couple of times and the string trick works.<br /><br />Let us know how things turn out.<br /><br />-John
