fresh water flush port start up

[larson260]

Volvo 320-CE-B. The raw water cooled engine was marina winterized with antifreeze. Is it safe to start it up if connect a hose to the fresh water flush port(blue plug). I want to run it for a short time before it goes in for survey and sea trial.

I would run it on muffs myself

Yes, you can run the engine if you plug your hose into the blue cap flush port. I wouldn`t run much above idle.
