When not wasting my time destroying the 1967 60 HP Evinrude that's been wasting a lot of space on this board lately, I've revived a couple of dead motors including the Mc Culloch. <br /><br />From what I can gather from a 1970 ABOS multi-make service manual the little pipe on the exhaust cover that is connected to the second water pump is a bilge pump connection, but I can't find any more info about it.<br /><br />Anyone know if there was some sort of pump or filter or other connection at the end away from the motor or or did it just run a hose direct into the bilge or wherever and suck water up?
