Let me preface this by saying this does not always happen but most of time. Boat will not come off plane, just almost makeing it to full power while doing this makes fluctuating high pitching sound. Then suddenly will go like hell like it was wound up. It will then unannounced go back to no power but never really dies just putts. I have replace power packs & checked for spark and sound difference by pulling off plug wires one at a time. had thermostats replaced thinking it was running too cold. had carbs rebuilt. Major symptom i see now is it is spitting gas / oil from the spitter and cooling outlets. Enough to make the water around the slip pretty slick. i will next check the compression. I would have done that first but i do not have a tester. I was first thiking bad gas but has happend over many tanks. Could it be stator or would that just die and not intermitently work? Any help would be appreciated. I hope it is not a blown engine. Help
