Abstract
A lubricating and drive system for a marine propulsion transmission that is comprised of an upper reversing transmission and a lower final drive transmission. A lubricant pump is driven off an input shaft to the reversing transmission for supplying lubricant for actuating its clutches and also for lubricating its gears. The pickup for the lubricant pump is disposed at a lower position in the final drive gear case so as to maintain a low lubricant level therein when the unit is operating so as to reduce drag.
