Both motors overheating during dewinterization

If you haven't clamped off the cooling hose inside the engine, you need a very strong flow of water for it to work its way up and into the engine for it to cool properly. If no water is coming out the pisser then the engine isn't getting cooled by the water.

Well, I backed into the water and rabbit for 5-10 min on idle with no issues. Then took it out and worked my way up to wide open... again no issue. It’s a mystery, but I’m thankful.
