How can you check if your getting exhaust water revision?
Aside from the obvious hydrolock symptoms is there a method to see if revision is happening when there are no running issues?

if you have a riser style exhaust you can pull both risers off after running for a tad. See if water has collected down in the exhaust side of the exhaust manifolds internally . Look at the lowest point and in the corners of the exhaust manifold internally,
Or you can pull spark plugs and examine them for small water droplets --- plus crank the motor over to see if water or a mist spray of water comes out of the spark plug holes. I would unhook the fuel pump(s) and ignition side as well before cranking the engine over.

Yeah? Well I had a 496 boat that was steaming out the exhaust on the lake after starting up with engine still warm and it would continue to steam while idling. Finally the water showed up in the oil. Engine ran great. Pulling the exhaust revealed that the inner sleeves had been cut down to improve flow to the divertors on the Q&Q exhaust. We are talking about boats and not GMC Sierras.

condensation forming in the exhaust can do this as well. (steam) also cool out outside air with a certain amout of humidty. On marine exhaust condensation builds on the internal walls of the exhaust until they get warmed enough to burn that off. Thats one of the reasons for the tubulator riser / manifold gaskets is to collect condensation in the dam portion then have it burn off when its gets hot enough.
