sounds like reversion has been an issue.

I wonder if boats that haven't been drained of water in the engine have a problem with inclines? I know 1 PWC in particular that the water inside the exhaust for cooling rubber hoses, would run back and into the front cyl if you didn't blow the water out and backed the ski down a hill.
In my situation, I pull the drain plug from the bilge, but I have to back the trailer down a decent hill to where I park it, and normally drain the pipes when not being used for a few days. (fresh water)
Do I need to worry about water from the block filling the headers and running back into the exhaust? (CMI Fusion headers) My guess is no since the engine pulses aren't sucking the water backwards, but figured it's a good time to ask. Thanks guys..

In my case it was.
Engine builder removed the heads and a couple valve seats were pitted pretty good. (bought a used engine, ran for 1 season and already in for complete rebuild. )
HP 500 carb. Engine had CMI headers on it in the video the seller sent me. Pits look to have been there for some time. I'm running CMI Fusion headers but was wondering if me backing the boat down a hill had something to do with the water intrusion. (se previous post ^^^^^)
