AHAB KS1 Posted April 26, 2010 Share Posted April 26, 2010 (edited) A petcock was removed from our 5.0 liter Mercruiser last fall and we can't find where it goes. The 2 petcocks located on either side of the engine, midway back and all the way on the bottom are in place. The mystery location is somewhere on the starboard. Any clues you guys have would be greatly appreciated. :searchIt could be an exhaust drain. Unfortunetly I wasn't the one who took it out but it's a start. Thanks. But I have 1 more question. I take it the location is somewhere above the spark plugs. Is it more forward or aft of the mid section of the engine? Edited April 26, 2010 by AHAB KS1 Would like more detail Link to comment Share on other sites More sharing options...

1mainiac Posted April 27, 2010 Share Posted April 27, 2010 There should be one on each side often they don't drain well so guys pull them out. check the other side locations will be similar on each side Link to comment Share on other sites More sharing options...
Nailer Posted April 27, 2010 Share Posted April 27, 2010 Exhaust should be a bet more to the aft. Link to comment Share on other sites More sharing options...
