    • Lubricating system especially applicable to an outboard-inboard marine drive system. The entire power train housing is filled with lubricant to a point above the upper gears therein and the rotation of the drive shaft is utilized to pump lubricant through suitable separate channels from the relatively cool underwater housing to the relatively hot above water gear box and return, thereby providing a constant flow through the underwater housing for cooling same, a constant supply of cool oil to the upper gear box and a constant circulation thereof to prevent localized overheating. In the specific embodiment here disclosed the vertical drive shaft is hollow and utilized for the upflowing oil while the channel outside thereof and including the bearings therefor are utilized for the downflowing oil. A suitable impeller is placed on the drive shaft to cause the circulation.
