    If yes, please refer the engine's behaviour.Personally my new carburated 350 has vibration and overheating.Signs of rust at #7 spark plug.Would a stuck shutter cause the water to get in the exhaust manifold?

    4hp-Mercury no water from the outlet

    According to my experience in Mercruiser i would say that if the water inlet was covered by water the water pump would work.But either i have some leak or my assumption is not right ,or it sucks air from the vent hole.Water comes out normally only when the water covers the red line.Please...

    Has anybody modified an intake manifold for 305 to 350 swap ?

    You can't imagine my disappointment when i find out that it wasn't the bolt's size but the different angle that the central bolts didn't fit. Do you think if i fill in (welding) the 4 central holes and i open new ones at the right angle that will work? #the 305 is 1979 the 350 is brand new old...
