To test for a cracked engine, everyone says to start it up and watch for water leaks. I have never had a inboard only outboard and I know if you start them without water you can burn them up. This is a Mercruiser 3.0L engine. Can it be run without being in the water? Thanks

Re: Testing engine

you would need to put muffs on the water intake on the sterndrive <br /><br />ANY DRY RUNNING will dammage the raw water pump which is inside the sterndrive<br /><br />tommays

You should block off the water passages,+ Pressurize with Air,... about 10/ 15lbs will do,..... <br />And Listen for the Leaks............. ;) <br /><br />As tommays says,..... Don't run it Dry,.. Not even cranking it over on the Starter,.... <br />You'll Smoke the Impeller in Seconds............
