Patented Aug. 11, 1931 RUSSELL J. POULIOT, F DETROIT, MICHIGAN, ASSIGNOR, BY MESNE ASSIGNMENTS, TO DEE WITE, INCORPORATED, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN OUTBOARD MOTOR BOAT Application filed June 14, 1929. Serial No. 370,7?9.

This invention relates to outboard motor boats and the object of the invention is to provide a motor boat in which the outboard motor is entirely concealed within the boat without destroying the lines and appearance of the boat.

Another object of the invention is to pro vide an outboard motor boat having a transom forward of the stern on which an outio board motor may be mounted, the boat being provided with an aperture in the bottom rearwardly of the transom through which the lower end of the outboard motor extends.

Another object of the invention is to provide an outboard motor boat in which the outboard motor is entirely concealed and in which the motor compartment is ventilated to withdraw the exhaust fumes therefrom.

A further object of the invention is to provide a transom extending across the boat forward of the stern on which the outboard motor may be mounted, the boat being provided with an aperture rearwardly of the transom and a partition on each side of the aperture between the transom and the stern.

A further object of the invention is to provide an outboard motor boat of the character described having a hinged hatch extending over the rear portion of the boat between the transom and the stern, protecting the outboard motor from the weather and concealing the outboard motor within the boat.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained isshown in the accompanying drawings, in which Fig. 1 is a plan view ofthe stern of the boat taken below the deck.

Fig. 2 is a section taken on line 22 of Fig. 1.

Fig. 3 is an elevation of the rear end of the boat.

Fig. 4 is a sect-ion taken on line H of Fig. 1.

Fig. 5 is a View of the forward end of the motor hatch.

As will be noted from Fig, 3 the stern 1 of the boat is provided with an opening 2 therethrough extending above the water line. At each side of this opening 2 and within the boat. as shown in Figs. 3 and 4-, is a partition 3. These partitions 3 extend forward to a transom 4 which extends across the boat and is h ted and caulked in place to prevent passage of water forward of the transom. The partitions 3 are also canllred to the transom 4i and stern 1 and to the bottom of the boat so that water cannot pass into the chambers'5 and 6 on opposite sides of the opening 2 in the rear of the boat. As will be understood from Figs. 1 and 2 the opening 2 in the rear end of the boat extends through the bottom of the boat and between the partitions 3 to the transom i. This provides a space through which the lower end of an outboard motor may extend into the water beneath the boat.

It will he noted from Fig. 3 that the aperture 2 does not extend as high as the transom 4 but at the same time the transom 4: is low enough so that when an outboard motor is mounted thereon between the partitions 3 the outboard motor will be entirely concealed within the lines of the boat. This brings the center of gravity low in the boat so that the boat has less tendency to roll. When travelling at high speed and in making sharp turns in which the boat is banked water sometimes has a tendency to pile up against either partition 3 forming the sides of the opening for the outboard motor. In order to prevent this water from coming up over the partition 3 a plate 7 is mounted over the opening 2 and is provided with a notch Z therein. About the notch 8 the plate 7 is provided with a downwardly extending flange 9 shown in Figs. 1 2 and 4, and this flange 9 deflects the water downwardly and prevents it from coming up over the partition 2. it will thus be seen that even on a sudden turn where the water is thrown up 'b'oat'iines' and by means of the swung upwardly to allow the outboard motor .to be mounted in the rear end of the boat on the transom t between the partitiims o and after the motor has been properly mounted the hatch is swung down to cover the motor. A curtain 15 is attached to the forward end 16 of the hatch, as shown in Fig. 2, and e):- tends downward forwardly of the transom 4 thus closing off the motor compartment from the remainder of the boat and confineing the smoke and exhaust fumes of the engine to the motor compartment. In. order to efiicientl I exhaust these fumes from the nentthe'ports loand A are provided in the forward and rear ends of the hatch respectively so that by travel of the boat in a forward direction a flow of air passes through the ports 13 and 1a in a rearward direction thus maintaining a continuous flow of air through the top of the motor conipartment and thus carrying the exhaust fumes out of the compartment through the ports 14- and away from the passengers in the boat. T he curtain 15 when not in use is rolled up within the top of the hatch as shown in dotted lines in Fig. 2.

This hatch protects the motor and in a rain storm with the curtain down forward of the motor there is no danger of the motor being short circuited and by means of the plate 7 and flange 9 the water in which the boat is riding is deflected downwardly away from the motor thus preventing short cir- "cuiting' of the motor by water forcing up- .wardly through the opening 111 the bottom of the boat. By carrying the opening 2 through the stern of the boat to a point above the water line, as shown in Fig. 3, should the motor strike an obstruction the usual shear pin provided for this purpose will be sheared and the end of the motor may swing up into the opening 2 in the stern of the boat so that it will clear the obstruction without damage to the propeller and lower end of the outboard motor.

From the foregoing description it becomes evidentthat the device is very simple and efiicient in operation, will provide an outbom'rmot'or boat 'inwhicn the outboard inotor is entirely concealed within the lines of the boat without destroying the effect of the construction shown a device 1s provided which accomplishes the Ob ects described.
