Should there be exhaust exiting from upper relief ports on midsection or just water on a 1979 Johnson 150?? I only have water and quite a heavy stream at that!! Thanks....

Yes, if you are talking idle speed. Suggest you check your thermostats.

Re: upper exhaust relief ports

Thanks for the reply. Motor runs great on muffs but at lake it struggles to idle and dies going into gear. With NO exhaust coming out relief ports, kinda makes me wonder if exhaust is restricted? Any ideas??
