    1979 Johnson 9.9 Water Exiting Exhaust Relief Holes

    Awesome, thanks for the reply! I changed the water pump and gasket between the powerhead and now it's just blasting out the upper exhaust relief. There's good flow out the tell tale too. I'll probably start another thread once I run some more tests.
