Abstract
A lubrication system for an outboard motor engine includes a pump housing includes an inlet port through which lubricant enters the pump housing and an outlet port through which the lubricant is discharged from the pump housing. Both the crankshaft and the driveshaft extend through an opening defined at the pump housing and are couple with each other within the pump housing. A first seal member is disposed around the crankshaft for sealing a first location between an outer surface of the crankshaft and a first inner surface of the pump housing that defines at least a portion of the opening. A second seal member is disposed around the driveshaft for sealing a second location between an outer surface of the driveshaft and a second inner surface of the pump housing that also defines at least a portion of the opening.
