Abstract: A shaft pressure ring for use in conjuction with a boat having an inboard motor and a drive shaft protruding through a shaft logseal assembly mounted in the hull of the boat, the hull including a shaft log area surrounding the drive shaft, the shaft pressure ring comprising a deflector, the deflector having an inside diameter being annular in shape, the deflector being of a rigid material and adapted to be positioned upon the drive shaft a sufficient distance from the seal such that the shaft pressure ring will deflect a portion of the water passing beneath the hull of the boat in a direction toward, and onto, the shaft log seal. The splasher will continuously lubricate and cool the shaft log seal to prevent drying, burning, deterioration, and eventual leakage.
