[0053] The upper end 620 includes a first point 622, a second point 624, a body extension 625 extending from the first point 622 to the second point 624, and a cavity 626 extending from the first point 622 to and through the second point 624, and is preferably configured to function as a flange where a mounting housing member 250 which secures or mounts a jet assembly housing 181 to the motor 502, makes contact with or is located in proximity of the second point 624 of the upper end 620 of the fluid sealing member 600.
[0054] The cylindrical body 630 includes the first point 632, a second point 634, a body extension 635 extending from the first point 632 to the second point 634, and a cavity 636 extending from the first point 632 to and through the second point 634. Preferably, the cylindrical body 630 has a predetermined length or height and is positioned external of the motor shaft hole 512 when the fluid sealing member 600 is inserted into or positioned in the motor shaft hole 512.
