OMC L6 (GM) 250 cid:<br /><br />Stamped on the "old" OMC manifold is the letter "B" above this number: 909008<br /><br />It's a '73 model. I'm finding a million manifolds on line but they all have 3 water ports going to the riser and mine has 4 (one on each side)...<br /><br />HELP!<br /><br />**UPDATE**<br /><br />I have to get a new riser... Nobody makes the manifold with 4 water outlets into the riser anymore! Oh well... New parts is good parts!
