This will vary based on water injection or simple venting. I have one on my charter boat that has water supplied to it after the heat exchanger on the engine. On my trawler the water feed is before the heat exchanger. Some installations simply run a vent line, so there is no real water flow. Which setup do you have?
My preference is water supplied before it goes through the heat exchanger. Although I've never had a problem with the one after the heat exchanger on my charter boat either. Think that one now has about 7,000 hours on it.
I'm tired of fast moves, I've got a slow groove, on my mind.....
I want to spend some time, Not come and go in a heated rush.....
