A buddy is looking at a pontoon with a '96 120 Force. The guy who owns the boat says that after a few minutes running at WOT it will drop from 5000 rpm to about 3000 rpm. The gentleman has already replaced all 4 CDM (coilpacks) and also had the carbs redone but problem still exists. I told him it sounded like stator and he wanted me to check it. I don't have a manual for the engine and I'm not sure how to check it on these newer Force engines. Anybody done one of these?? Thanks.............
