A principal feature of the invention is the above described cowl assembly and mounting means. These provide easy installation and removal of the covers, improved vibration and noise isolation, and improved sealing of the power head.
Another principal feature of the invention is the above described grommet arrangement for connecting an exterior device such as a fuel tank or a remote control system to the engine. This arrangement eliminates the need to disconnect the fuel system or remote control system when removing the rnotor covers.
Another principal feature of the invention is the means for mounting the cowl members on the sides of the propulsion unit. This is advantageous because large outboard motors are commonly lifted by fork lifts with the forks being L3'7~
positioned beneath the lower cowl members anc1 extending in the ore and aEt direction on either side of the propulsion unit. On outboard motors having the lower cowl members connected to the drive shaft housing beneatn the power head or engine, such ~ifting can cause substantial stress on the lower cowl members since the forks are usually positioned outside of the power head, some distance from the point at which the lower cowl members are connected to the drive shaft housing or propulsion unit. This problem is substantially avoided by the present invention since the lower cowl members are mounted on the sides of the propulsion unit, and more particularly on the sides of the drive shaft housing and the power head. Thus, the forks of a fork lift will be positioned almost directly beneath the points at which the lower cowl members are connected to the propulsion unit, so that the lifting forces are transferred almost directly to the propulsion unit, with little stress being placed on the lower cowl members.
Other features and advantages of the invention will become apparent to those skilled in the art on review of the follo~ing detailed description, claims, and drawings.

Furthermore, the recesses 50, 51, 56 and 57 are preferably tapered, and more particularly frustoconical. In the preferred embodiment, as bast ~3~70 shown in Figs. 3 and 4, the resilient mounting members 52 and 58 are connected to the opposite sides of the power head 30, and the resilient mounting members 53 and 59 are connected to the opposite sides of the adaptor unit 24.
In the preferred embodiment, as best shown in Fig. 5, each of the mounting means includes a mounting pin 64 extending generally horizontally from the propulsion unit 12 (i.e., from either the power head 30 or the adaptor unit 24), with one of the resilient mounting members 52, 53, 58 and 59 mounted on each of the mounting pins 64. In the preferred embodiment, each of the mounting pins 64 has an annular groove 65 around its outer endl and a clip 67 can be fastened in the groove 65 to secure the respective mounting member 52, 53, 58 or 59 to the mounting pin 64~ Preferablyl each of the mounting members 52, 53, 58 and 59 is tapered so that each member becomes wedged in its respective recess or aperture when the lower cowl members 38 and 40 are connected to the propulsion unit 12. More particularly, each of the moun~ing members 52, 53, 58 and 59 has a ~enerally frustoconical shape complementary with the shape of the recesses or apertures 50, 51, 56 and 57. In the illustrated construction, each of the mounting means also includes a washer 66 located between the mounting member 52, 53, 58 or 59 and the side of the propulsion unit 12. As best shown in Fig. 5, when the mounting member 52, 53, 58 or 59 is properly located in its respective aperture 50, 51, 56 or 57, the respective lower cowl member 38 or 40 is isolated from the propulsion unit 12 by the resilient mounting member.

While various suitable compressing means can be employed, in the preferred construction, the compressing means includes the bolts 46. Thus, as the bolts 46 are tightened to connect the lower cowl members 38 and 40, the mounting members 52, 53, 58 and 59 are compressed between the lower cowl members and the propulsion unit 12.
In the preferred embodiment, the cowl assembly 36 includes resilient seals 68 along the split line between the left and right lower covers 38 and 40, and a resilient seal 70 around the adaptor unit 24 for sealing the lower cowl members 38 and 40 to the adaptor unit 24.

Also, each of the lower cowl members 38 and 40 includes an inwaedly extending flange 79 which abuts the seal 70 when the lower cowl members 38 and 40 are mounted on the propulsion unit 12. The seals 68 and 70 are compressed when the lower cowl members 38 and 40 are connected. ~he seals 68 and 70 provide substantially total sealing of the lower cowl members 38 and 40 to the propulsion unit 12.
Preferably, the upper cowl member 42 has a lower edge portion 72, and each of the lower cowl members 38 and 40 has a forward upper edge portion 74 having therein a downwardly extending slot 7~
76. The outboard motor urther comprises a grommet 78 removably received in the 510t 76 in the right lower cowl member 40, a grommet 80 removably received in the slot 76 in the left lower cowl member 38, and means detachably connecting the upper cowl member 42 to the lower cowl members 38 and 40 with the lower edge portion 72 of the upper cowl member 42 mating with the upper edge portions 74 of the lower cowl members 38 and 40 and trapping the grommets 78 and 80 in the slots 76. While various suitable connecting means can be used, in the preferred embodimentr the connecting means includes the latches 44.
The grommets 78 and 80 are adapted to receive or be connected to control or supply lines connected between the engine 34 and a device located exteriorly of the cowl assem~ly 36. In the preferred embodiment, the grommet 80 is removably connected to a fuel line 82 which communicates with the engine 34, and to a fuel line 83 which communicates with a remote source of fuel (not shown), and the grommet 78 receives shift and throttle control cables 84 connected between the engine 34 and a remote control apparatus ~not shown) such as a single lever control.
When the cowl assembly 36 is removed from the propulsion unit 12, the grommets 78 and 80 are removed from their respective slots 76 and the fuel line 82 and the shift and throttle cables 84 remain connected to the engine 34.

This arrangement eliminates the need to disconnect the fuel system or remote control system when removing the rnotor covers.
Another principal feature of the invention is the means for mounting the cowl members on the sides of the propulsion unit. This is advantageous because large outboard motors are commonly lifted by fork lifts with the forks being L3'7~
positioned beneath the lower cowl members anc1 extending in the ore and aEt direction on either side of the propulsion unit. On outboard motors having the lower cowl members connected to the drive shaft housing beneatn the power head or engine, such ~ifting can cause substantial stress on the lower cowl members since the forks are usually positioned outside of the power head, some distance from the point at which the lower cowl members are connected to the drive shaft housing or propulsion unit. This problem is substantially avoided by the present invention since the lower cowl members are mounted on the sides of the propulsion unit, and more particularly on the sides of the drive shaft housing and the power head. Thus, the forks of a fork lift will be positioned almost directly beneath the points at which the lower cowl members are connected to the propulsion unit, so that the lifting forces are transferred almost directly to the propulsion unit, with little stress being placed on the lower cowl members.
Other features and advantages of the invention will become apparent to those skilled in the art on review of the follo~ing detailed description, claims, and drawings.
