my G2 250 HO will bogg and drag then eventually get on plane and run fine. when idling it sounds like its missing on a cylinder but once it gets on plane i can peg out RPMS. Ive changed spark plugs, spark plug boots and spark plug wires and wasnt it. No codes are thrown. I was thinking maybe a power pack went out? HELP! Thanks.
You may need to contact your dealer so they can run the motor with the Evinrude diagnostic software connected to individually turn on any cylinder or richen and lean it to find out from where the miss is originating .
