    Bogging Out?

    I have a 1988 25HP manual start Evinrude.<br />I decided to test it on the lake today. When I start increasing the throttle it runs fine until it reaches a certain rpm and then it boggs... I can't increase the throttle past that point at all or it boggs. I don't have an rpm gauge but the revs...

    Short Shaft Kit?

    Ignition Timing

    Stalling

    I have a 1988 25Hp Evinrude outboard. I'm having a problem where it stalls when you raise the throttle a bit. Anyway I've checked a bunch of things but not the timing. I know how to check the timing but if it's off how do you adjust it?

    Hi all, I have a 1988 25Hp Evinrude Outboard. I'm getting it ready for the summer, so I decided to run it in my driveway with the flusher ears on it. It runs good at idle and when I give it throttle it revs high and sounds good like you would expect. Then all of a sudden it boggs out. If I...
