ABSTRACT:
A through hull assembly to be incorporated in a marine drive has a housing secured to the hull. The housing consists of a rearward tubular section and a forward section. The tubular section is of a length to extend through the hull and is connected and sealed thereto in a manner preventing leakage through the passageway through which the tubular section extends. A shaft extends through both housing sections and is sealed to opposite ends thereof and is supported by bearings in each section with the ends of the shaft exposed. The bearings in the forward section are accommodative of forward and rearward thrusts. A lubricant reservoir maintains the housing full with the lubricant level in the reservoir giving information if there is any housing leakage.
