I'm suspecting a leak in one of my risers. I was able to pressure check my exhaust log water passages with a gauge and hose setup and they held.
I'm thinking maybe the riser is leaking water internally from the dump line somewhere back into the exhaust manifold. Plugging the small rectangular outlet port inset at the back of the riser to do the test is proving difficult though. Anyone got any suggestions?

*edit* These are older Harman Marine risers. The line for the engine water
dump into the exhaust riser is in front of the riser curve. The design seems such that if the passage is compromised, it could flow water into the exhaust log. Maybe I should just upgrade to something newer that also gives a temperature port...
