Abstract: An engine (10) includes a starter (28) mounted to the top portion (11a) of a crankcase (11). Further, engine (10) utilizes a flywheel (23) which has its teeth (23c) as an integral one-piece unit.
Abstract: A unique method of manufacturing a liquid cooled cylinder block by means of a die-casting process is disclosed. The cylinder block (12) has a bore (15) with a plurality of apertures. There is an intake passage (24) through the cylinder block (12) which terminates in an intake port (25) in the bore (15), and an exhaust passage (29) that extends from an exhaust port (31). There are also a plurality of scavenge passages (27) which terminate in scavenge ports (28). The scavenge passages (27) interconnect the bore (15) and the combustion chamber (18). The scavenge passages (27) are formed by means of a pair of side covers (37) which are attached to the cylinder block (12) by means of a plurality of fasteners and a gasket (43). Suitable coolant enters via coolant passageway (44) and circulates through coolant passageways (33, 38, 50, 60).
Abstract: Disclosed is an intake and pump assembly (101) for an aquatic vehicle (10) and a method for disassembling an intake and pump assembly. The intake and pump assembly (101) includes an intake housing (18), a pump body (66), and a discharge nozzle (79). The intake housing (18) is provided with an intake grill (89) and flow director (85). The impeller (17) is surrounded by a wear ring (58). A vane (72) is integrally formed within the pump body (66). The drive shaft assembly (37) is provided with couplers (30, 33) and ball guides (26, 50 ) of resilient material which interconnect the component parts of the drive shaft assembly (37) and absorb shock and misalignment. Stacked washers (61) are provided for adjustment purposes.
