OK im stumped, I have a 1988 Yamaha 150 ETLG 2 stroke that is not using the direct oil injection, it has all been disconnected. It seems to be only running on the 3 left cylinders if looking form behind the boat. When I put one of those automotive spark testers with the enclosed bulb it shows strong spark on the left 3 and EXTREMELY weak spark, almost non existent on the right 3 cylinders. Compression good and matching on all 6 cylinders, I have replaced the stator, all 6 coil packs, control box, fuel pumps and regulator/rectifier. I have checked all the resistance setting per the CDI troubleshooting chart on the coils, stator and trigger wires and all within specs. I have removed carbs, took apart and cleaned all possible holes and jets. Only thing I have not checked was the DVA output numbers since Im waiting on the dva adapter for my multimeter. Before I spend the money on a new power pack I want to know if there is anything else I can rule out. Can the power pack be faulty on just the right side cylinders? does this year and model outboard have a safe/limp mode that has activated? starts and idles good but once you try to throttle up it doesnt go at all ( last time it was in the water) Any and all ideas will be investigated lol. Thanks
