Motor is new to me this season, idles nice on hose, starts easily, hot or cold, has fresh plugs. Hesitation when trying to get on plane. When at idle in gear, at 800 rpm in water, pulling either top 2 plug wires will cause stall, bottom wire has no effect. Only see a stong blue spark occasionally on that one .
Removed plugs, top 2 have light brown porcelain with some black on outer metal, bottom plug is wet with fuel.
I'm thinking coil is N/G. Thanks MartyD
