    I took a close look at the gearcase just now. No indication of any path from exhaust to water tubes. The inside actually looks pretty good, if nothing else all that oil kept it coated and slowed corrosion.
    Attached are 2 pictures, one shows the corrosion that has eroded around the lower water intake (still no puncture into exhaust tube) and the other shows the burn in from welding at the lower rear of the side intake cover plate.
