1957 QD-18 10hp Weap Hole Leak Blue Fluid

[nesheinw]

Just bought a 1957 QD-18 10hp in seemingly good condition. Put in a bucket of water, some bluish fluid started to appear floating in small pools on top of the water. Got it running ok. When I removed it from the bucket, found that a small weap hole was oozing/bubbling slowly this bluish fluid. The hole is on the front facing side, just below the lower unit seal...which is about 2 inches above the cavitation plate. It continued to ooze/bubble for 30 minutes or so. The hole appears as though it should be there, but the leaking does not seem ok. The seller listed the following work was recently done, so I don't want to tear into it if this is just something I should expect...just doesn't seem right.

{Work included Rebuilding the Lower unit. All new lowerunit seals were installed and a new water pump was put in during rebuild of the lower unit. Ignition was taken apart and gone through Coils are used but tested good. Points are in good working order New condensers were installed along with new Champion Spark Plugs. Carb was taken apart and cleaned and found to be in good working order}

I'm sure it's just extra two stroke oil that they added to the cylinders since it would sit for a while. Nothing else is blue. Don't worry it'll soon be replaced by disgusting brown/white/black ooze. It will come out of any number of places.

If you've run it in a barrel for awhile, take it out and leave the motor upright for awhile, and pull the bottom gearcase drain plug briefly.. If it looks like new lube, and not milky or watery, you're all good!

Good points from all... Thank you. I will check the LU fluid tonight and post my results.

Without going into a lengthy discussion of the anatomy of that m otor, let's just say that it has puddle drain valves to drain off excess fuel from the crankcase. That excess is dumped into the exhaust stream and winds up running out the bottom.

Check your gas, I think you will find that is blue. That should be a clue. In other words it is normal. But put it on a boat in the lake and get the carburetor adjusted right, and you will find it is much less noticeable.
