(My motor model and type is in my signature below)
The last few trips, my motor acts as if a plug is fouled when cold but only initial start (in winter, cold water).
Today, I ran the motor on the hose and checked eached coil with a timing light. Only the #2 cylinder is not firing. It's not the plug because the power source to plug is from the coil and I would have fire if the coil was doing it's job.
I changed the coil to an older "backup coil" but it only fired once. No intermittent flashing from the timing gun. This told me it's not the coil but either the CDI power pack or the trigger. I have recently changed the stator with a brand new stator so it's not that.
This issue would happen on rare occasions even when motor was warm. Motor would lug and not fire on all cylinders. Then when you try to get on plane, it would lug for a few seconds and then take off like normal. I figured it was a fouling plug. Now, I know it's probably a failing pack about to go or the trigger.
I'm going to swap power packs from one side to the other to see if the problem moves. If so, I'll know which pack is bad and that it IS the pack and not the trigger. If problem stays, it's probably the trigger. Could be a lose connection for all I know and a simple/easy fix.
Has anyone heard of this before? It's consistent when the motor is cold, completely inconsistent when motor is warm. Very rare when motor is warm for that matter. When it's warm, motor runs great.
