DESCRIPTION OF THE PREFERRED ENBODIMENT
Illustrated in the drawings is a marine propulsion device 10 mounted on a boat 12 having a transom 14. The marine propulsion device 10 is of the stern drive or inboard/outboard type.
As best shown in Fig. 1, the marine propulsion device 10 comprises a water cooled engine 16 securely mounted on the boat frame by suitable means such as rubber mounts (not shown). The marine propulsion device 10 also comprises a gimbal housing 18 mounted on the outer surface of the boat transom 14 and fixedly attached to the boat transom 14. The gimbal housing 18 can be attached to the boat transom 14 by any suitable means. such as bolts extending through the transom 14.
The marine propulsion device 10 also comprises a gimbal ring 20 connected to the gimbal housing 18 for pivotal movement relative to the gimbal housing 18 about a generally vertical steering axis (not shown), and a pivot housing 30 connected to the gimbal ring 20 for pivotal movement relative to the gimbal ring 20 about a generally horizontal tilt axis (not shown). Such a construction is well known in the art and need not be described in greater detail.
The marine propulsion device 10 also comprises a propulsion unit 34 removably connected to the pivot housing 30 for common pivotal movement of the propulsion unit 34 with the pivot housing 30. in the illustrated construction, the propulsion unit 34 is removably connected to the pivot housing 30 by a plurality of bolts 36. The propulsion unit 34 includes a propeller 38 mounted on a propeller shaft 40, and a generally horizontal drive shaft 42 having one end removably connected to the engine 16 and an opposite end having thereon a bevel gear 44. A universal joint 46 attached to the horizontal drive shaft 42 allows pivotal movement of the drive shaft 42 with the propulsion unit 34. The bevel gear 44 drives a bevel gear 48 on the upper end of a vertical drive shaft So. The lower and of the v4rtical drive shaft has thereon a driving gear 52. A reversible transmission selectively clutches a pair of driven gears 54 to the propeller shaft 40 to transmit forward or reverse motion to the propeller shaft 40 from the driving gear 52.
The marine propulsion device 10 further comprises means for pumping water from the exterior of the propulsion unit 34 to the engine 16. The means for pumping water includes a plurality of water inlet openings 60 in the propulsion unit 34, the inlet openings 60 being located so as to be underwater during normal operation of the marine propulsion device 10. The pumping means also includes a pump 62.
and an inlet passage 64 communicating between the pump 62 and the inlet openings 60. In the illustrated cotistruction..the pump 62 is located rearwardly of the horizontal drive shaft 42 and is driven by an extension of the horizontal drive shaft 42. Such a pump location is described in greater detail in the above mentioned U.S. Bland Patent Application S.N.
560,904, which is incorporated herein by reference.
It should be understood that other pump locations and other means for driving the pump are within the scope of the invention.
The pumping means also includes conduit means extending from the pump 62 to the engine 16.
While various suitable conduit means can be employed, in the preferred embodiment, the conduit means includes a conduit member 66 (see Fig. 2)-mounted in an opening 68 in the pivot housing 30, the conduit member 66 having opposite front and rear ends and a drain opening 70. A pair of O-rings 72 seal the joint between the conduit member 66 and the opening 68. A shoulder 73 on the conduit member 66 engages the pivot housing 30 at the forward end of the opening 68. The rear end (to the right in Fig. 2) of the conduit member 66 is externally threaded. and the conduit member 66 is secured in the opening 68 In the pivot housing 30 by a nut 74 threaded onto the rear end of the conduit member 66. The conduit member 66 is mounted in the pivot 6using 30 such that the rear end of the conduit member 66 extends rearwardly of the rear end of the pivot housing 30. The front end (to the left in Fig. 2) of the conduit member 66 forms a nipple.
The conduit means also includes a first conduit or water hose 76 communicating between the I k -9- 1 front end of the conduit member 66 and the engine 16 for conducting water from the conduit member 66 to the engine 16. The water hose 76 is secured to the nipple formed by the front end of the conduit member 66 by a conventional band clamp 78. The water hose 76 extends through the gimbal ring 20. through an opening (not shown) in the gimbal housing 18, and through an opening (not shown) in the transom 14 to the engine 16. The conduit means further includes a second conduit communicating with the pump 62 for conducting water from the pump 62 to the conduit member 66, the second conduit being automatically connected to the rear end of the conduit member 66 when the propulsion unit 34 is connected to the pivot housing 30, and being automatically disconnected from the conduit member 66 when the propulsion unit 34 is disconnected from the pivot housing 30. In the preferred embodiment. the second conduit is a water supply cavity 80 (see Fig. 1) communicating between the pump 62 and an opening 81 (see Fig. 3) in the fro nt end of the propulsion unit 34. The water supply cavity 80 and the conduit member 66 are located such that the rear end of the conduit member 66 extends into the water supply cavity 80 when the propulsion unit 34 is connected to the pivot housing 30. Therefore,'the water supply cavity 80 Outomatically communicates with the conduit member 66 when the propulsion unit 34 is connected to the pivot housing 30. A seal 83 surrounds the opening 81 and seals the joint between the pivot housing 30 and the propulsion unit 34 so that the water supply cavity 80 sealingly communicates with the conduit member 66.
The marine propulsion device 10 further comprises means for draining water from the conduit 10- means. In the preferred ' embodiment. the draining means includes. in the pivot housing 30. an internally threaded opening 82 (see Fig. 2) communicable with the atmosphere and. in the conduit member 66, the drain opening 70 communicating with the opening 82 in the pivot housing 30 so as to be communicable with the atmosphere. The conduit member 66 has a drain groove 04 communicating with the drain opening 70 and running circumferentially around the conduit member 66 to insure communication of the drain opening 70 with thi opening 82 in the event that the conduit member 66 is rotated such that the drain opening 70 is not aligned with the opening 82. The draining means further includes a drain plug 86 removably and threadably securable in the opening 82 in the pivot housing 30 so as to prevent communication between the drain opening and the atmosphere. As best shown in Figure 2, the drain plug 86 is inserted into the opening 82 from the exterior of the pivot housing 30 and is accessible from the exterior of the pivot housing 30.
In the preferred embodiment. the conduit means has a low point below both the pump 62 and the connection of the conduit means to the engine 16, and the draining means affords drainage of water from adjacent the low point of the conduit means.
Thus. the first and second conduits (the water hose 76 and the water supply cavity 80) and the conduit member 66 have a low point between both the pump 62 and the engine 16, and the drain opening 70 In the conduit member 66 Is located adjacent the low point.
The marine propulsion device 10 functions as follows. When the propulsion unit 34 Is connected to the pivot housing 30, the water supply cavity 80 Is automatically connected to the rear end of the conduit member 66, so that the pump 62 is connected to the engine 16 via the water supply cavity 00. the conduit member 66, and the water hose 76.
When the marine propulsion device 10 is removed from the water for storage, any water between the pump 62 and the inlet openings 60 will drain out through the inlet openings 60. When the drain plug 86 is removed trom the pivot housing 30, substantially all water between the pump 62 and the engine 16 (in the water supply cavity 80. the conduit member 66. or the water hose 76) will drain out through the drain opening 70 and the opening 82. Since the drain opening 70 is located adjacent the low point of the conduit means.
virtually all of the water between the pump 62 and the engine 16 will be drained. This will substantially prevent freezing of water in the water supply system and damage to the marine propulsion device 10 due to expansion of frozen water in the water supply system.
Water in the engine 16 Is drained in the conventional manner. such as by opening petcocks on the engine 16.
When the propulsion unit 34 is disconnected from the pivot housing 30, the water supply cavity 80 Is automatically disconnected from the rear end of the conduit member 66 No ot her disassembly of the water supply system Is necessary.
