Did you check for spark before you replaced that power pack and when you replaced it did you also replace the optical eye (EET)?
Looks like blown head gasket got water pumping in the cylinder in question...it is sparking.
No head gaskets on that motor O rings on each cylinder. Which one is it?
Bad power head to adapter plate gasket.
Have to pull the head off.
the entire powerhead
