Went night fishing, put boat in water, put it on plane and ran 1/4 mile. Ran fine. Pull into a creek was idling and watching my graph just checking things out, oil alarm went off so i turned motor off and just used trolling motor. When i got back to ramp started motor to load boat and no power to push boat up on trailer.
Since then i have checked multiple things trying to figure out what is the issue.
I have replaced stator and trigger because multimeter readings were low in my opinion and also the trigger had some cracks.
I've unplugged the wires for alarm and added oil to gas to ensure no damage to motor if auto mix wasn't working.
Starts fine, runs fine, but still no power.

(Also previous to this problem i recently changed spark plugs.)

Any suggestions?
