Attached you will see the area you need to work on. This is for a 35hp Gale, but they are all similar. Remove this panel, plug the drain hole that goes down into the exhaust cavity (High temp silicone works), then drill/tap the panel to accept a hose barb. Re install, and run a hose from the barb to a bottle. Now, the extra fuel/oil mix that is normally dumped in the lake can be re used or recycled.
I did one set up on a '57 35hp OMC where I modified it to run on a fuel pump, but kept the pressure tank. I kept the double line as well....used the old air side as the oil return, to make it look factory still.

That's exactly what I did on the engine ends, except I kept the original double line for fuel-air, and ran separate 3rd hoses to the clear bottles. I also have done this to a '57 Johnson this Spring, and ran the dump hose into a regular vented 1 gal plastic gas container to which I added a 1/8th x 1/8th barbed fitting epoxied to the yellow pour spout cap.
Think I'll do the same type of receivers for the twin Javelins. While one waste jug with 2 nipples would work, this intrusion episode is showing me the advantage of being able to keep an eye out for each engine's "contributions".
