Abstract

A jet propulsion unit for a boat includes a generally rectangular pump housing section extended through a transom opening. A seal unit includes an O-ring seal compressed between a pair of brackets secured to the transom about the opening. The bottom wall and the side walls of the unit and the opening are formed as a flat planar member. The upper wall of the housing is formed with an upwardly curved surface from an aft portion of the propulsion unit toward the inner portion of the propulsion unit to create successively changing cross-sectional area taken on a vertical plane through the unit and thereby maintain an essentially constant sealing requirement with the unit in the opening. The bottom surface thus defines a reference with the upper surface configured to accommodate transom angles between zero to 20 DEG while maintaining effective engagement of the single encircling seal member with the sealing surface of the housing. The seal unit thus encounters an essentially constant spacing between the housing and the seal bracket for all transom angles and a single unit may be used on all transoms. The rectangular construction of the housing locates the side walls spaced outwardly of a pump bowl wall and defines a discharge channel within which an exhaust pipe is located. This avoids the necessity of transom openings normally provided for the exhaust pipes as well as the requirement of a number of different fittings to accomplish the connection of the exhaust pipes through the transom. The exhaust is discharged into the water to also reduce the exhaust noise.
