I have a 1988 johnson 25hp.<br />Ran fine until I ran it for about 10 minutes with no battery hooked up.<br />Now it will not even place out my 14' jon boat.<br />It appears to idle fine, but no go!<br />Carb is clean as a pin.<br />I checked my coils and replaced the power pack after it didn't test out OK.<br />Someone at a boat ramp said he had a similar problem with a 15hp evinrude.<br />What do you think??
