We have a 88 Bayliner with the 3.0L OMC Cobra I/O, when we first got it, it would jerk every once in awhile while driving at full throttle. That jerk has now got to a point that it happens almost continuously at full throttle, and will happen a lot more while just cruising at slower speeds. At searching through multiple sights it looks likes its a problems with the shifting module, or cables. Can anyone help me diagnose this? or know what the fix is for the jerking? The engine doesn't cut out, and it feels almost like it does a brake check while your in a car, but usually continues normally afterwards, but recently has gotten violently worse. Any help would be appreciated, Thanks DC10
