I see the flush hose attached to the starboard exhaust manifold. Did you check to see if it’s sucking air into the pump? If that spring loaded connector doesn’t close properly, it’ll let air into the pump. Maybe that’s your issue? Put a good sealing cap on it to test. The blue cap that comes with the kit gets brittle after 2 years and won’t seal a leaking fitting.
The pictures in post #19 made me think. If you haven’t already, maybe you should replace the water hose that leads into the transom. Your earlier picture didn’t show a bad case of “bravoitis” but if you had that much growth and debris inside the lower intake ports, it’s very possible that something is stuck inside the hose.
Thanks for the suggestions. I did check the flush valve and it doesn't seem to be leaking. You are right on the transom hose though. When I checked it, I was just looking for any build up at the transom wall that was similar to other pictures I had seen of bravoitis. I didn't actually try to back flush the hose while the outdrive was off and confirm nothing was stuck in the middle of it somewhere. Thinking back now that seems like an obvious thing I should have done. I'll have to pull it back out, but at least once out that is a pretty quick thing to check. The hose itself looked pretty new which is why I didn't change it.
