A couple weeks ago while buzzing along on Lake champlain in 2-3 footers I lost rpms. It dropped from 5400 and 52 mph to 4000 and 40ish mph at WOT. At the ramp while waiting to load it was stumbling, sneezing and stalling while idling.
I brought it home and got a compression guage. All cylinders measured between 95 and 105. I checked the wires and reinstalled the plugs. Plugs all looked good to me with the electrodes the same light chocolate brown color. These were also new plugs this year.
Took it out today and it seemed to intermittantly run strong and then run weak. I am thinking I am intermittantly loosing some spark to a cylinder. Does this sound like a power pack issue? Or could one spark plug have possibly gone bad?
