    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….
