Re: 18 HORSE EVINRUDE
The symptom you describe could have a number of causes. Start with the simple things first. Check your fuel lines from the tank. Make sure the vent is fully open and that the lines are not crimped anywhere. If you have a two-line system, there may be a problem with the pressure tank.<br /><br />next in line would be fuel pump and carburetor. If failure is only at high speed, and probably one cylinder, it's most likely a dirty or partially clogged jet in the carb.<br /><br />But these are broad guesses. You need to supply the year/model number of your motor so folks can better assist.
