High pressure flushing

[Jacktrop99]

Strange question but does flushing your outboard with to high of pressure cause any harm? 3 times I’ve ran the hose fully open on the flush port “02 ox66 250” and have been wondering why the pee stream is so strong with some water coming back out the connector, Seems like my Marina re did the dock hoses, Just realized this but motor runs good with new impeller

Maybe your hose connection has a leak/isn't tight... does it have the washer in there? There shouldn't be any leaking - but as to your question, no, there's no problem as to what you asked about.
