      billw- thats good news that my ’81 25hp is excluded from the corrosion issue.. This motor runs great and was a fresh water motor till i got ahold of it.
      Thanks, Jim PSB

        Throw your Champion plugs away and try a set of NGK’s. You’ve got nothing to lose and possibly a whole bunch to gain.

          Thanks Mumbles. I’ll give that a try as well. Interesting coincidence I just remembered – when I was originally given this motor it had NGK plugs in it.

            Reread your post, and it does read “right up to full throttle”…….So, you are most likely dealing with an ignition miss….Hopefully the cam and points adjustment will take care of the issue….
            If not, I would monitor ignition performance with a timing light or inline neon tester to isolate which cylinder is messing up….
            And yes, the older 22CI powerheads were prone to sleeve corrosion in salt water, but I’m betting/hoping this isn’t the issue in your case…
            One final question, which OMC ignition kit did you use? The 172523 OMC ignition kit has different condensers and it meant for the larger hp engines like yours….. Just a thought….

              I used the 172523 ignition kit. I’m taking the motor out again today for another test.

                  GREAT! Glad the issue was minor after all….

                    Lesson learned (again) – when all else fails, read the directions!! Like in, “TOP” on the magneto cam means UP!!!

                      My old supervisor at work used to tell all his guys, “READ THE DESTRUCTIONS!!” (He said it that way on purpose….)

                        That’s Interesting. The condensors in that kit are a different capacitance? Or longer wires? Both? I see that the other kit 172522 is said to be for 3-40HP as well. Maybe that’s a vendor error?
