<p>EXHAUST TUBE MOUNTING APPARATUS FOR OUTBOARD MOTORS In an outboard motor, the engine exhausts through the drive shaft housing in which an exhaust tube directs the gases into a lower propeller unit secured to the housing. The exhaust tube has support lugs on the opposite top sides. Bushings encircle each lug and they rest in receptacles on the upper interior portions of the housing. An adapter plate is secured to the housing, clamps the lugs in place and moves the lower end of the tube into sealing relationship within a lower bushing within the housing. The lower bushing is a rubber-like annular bushing having a projecting ledge aligned with the lower end of the exhaust tube. The inner wall of the bushing has an inwardly and downwardly extended lip deflected and sealing with the side of the exhaust tube.</p> |
