This invention relates in general to a motor boat and has more particular reference to a silencing and shock reducing engine mounting for an outboardmotor at the rear or transom of the boat. One of the principal objects of the invention is in the provision of a resilient mounting for .the motor of a motor boat to reduce the jarring and noise in the boat both of which are'so objectionable .to- 19 the occupants.

A further object of the invention is to providea mounting for cushioning the motor in a boat to minimize vibration and shaking and thus to prevent damage. to and leaking of the boat.

A further object of the invention in the provision of a yielding mounting for the motor of a high speed motor boat.

A further ob ect of the invention is in the g0 provision of an outboard motor mounting which reduces vibration-and shaking of the boat and silences the boat reverberation.

A- further obj ect 'of the invention is in the 7 llustrating a preferred embodiment of the 85 invention.

In the drawings Fig. 1 illustrates an outboard motor' in side elevation as applied to the stern of a boat; Fig. 2 is a perspective of the stern of a boat constructed in accordance 0 with the principles of this invention; and

Fig. 3 is a section taken on the line 3-3 of Fig. 2. I

In propelling a motor boat in the water, and

more particularly in the highspeed type of motor boats the-jar and'vibration of the motor not only shakes the boat and its occupants but also the vibrations transmitted directly from the motor to the boatcause a considerable noise and reverberation, magnify the sound of the motor so that it is very objec .tical axis for steering.

tionable to the occupants of the boat and ar- I ticularly upon small bodies of water pro uc-' ing a noise which is even objectionable in the general vicinity ofthe boat. Another objection is that the continual vibration and shaking of most typesof boats is injurious and damaging to the construction of the boat itself tending to loosen and weaken the parts ian ll their connections and to cause the boat to ea The above objections are particularly true of the present type of high speed outboard motor boats in which t e motor is mounted I i at the rear of the boat and the'boat itself is j of light hollow form such that any'noise or vibration is magnified and reverberated by the'hull of the boat making it a sounding board or drum for magnifying and transvmitting the noise of the motor.

The present invention proposes to overcome these objections by providing a boat 51 having a motor support or transom 6 with a separate section 7 which may be attached to or separated from the remainder of the transom as shown more clearly in Fig.2. Be-- tween the sections of the transom a'yielding, resilient and substantially water proof material8, such for example as rubber is inserted,

preferably having flanges 9 which overlap the adjacent edges ofthe transom 6 and the section 7 so that'an attaching plate 10 may be applied over the'flangesboth inside and out and the edges thereof separately secured through the 'correspondin edges of the flanges to the transom and t e motor mounting section 7 by fasteningdevices 11 such as nalls or screws. This construction provides awater tight resilient joint in which there is no direct contact'between the transom and.

the motor mountingsection, but. only a reyielding and shock absorbing connecsilient tion. v An outboard motor designated'general-ly by the reference numeral 12 in Fig. 1 has a a pivotalmounting bracket 13 adapted to be secured to the transom of a boat and having parallelguides 14 which are a part of the mounting connection in which the outboard motor is rotatable about a substantially ver- The. mounting bracket 13 is adapted to be engaged over the top of themountin section 7 an to be held in place at the 'insi ethereof by fastening screws 15 so that the entire outboard motor is supported entirely by the mounting section 7 and does not engage or come in contact with any other portion of the.

tion or noise of the motor is directly transferred to the body of the boat except through as connection with the remainder o the resilient joint which connects the mounting sections 7 with the remainder of the tran-- som. It is' obvious that various changes in the construction, combination and arran ement of the parts may be made without eparting from the spirit and scope of the invention.

I claim:

1. A yielding) boat mounting for a motor comprising a cat section resiliently connected to the remainder of the boat and to which section the motor is attached.

2. A boat having a boat portion yieldingly connected to the remainder of the boat, and a motor attached to said portion for reducin the shock transmitted to the remainder 0 the boat.

3. A boat, an outboard motor a mounting for the motor having the boat. 4. A boat having a part thereof constitut ing a substantially vertical engine mounting and; having a portion with a. shock resisting therefor, I a substantially vertical boat part constituting a resilient r attached both to the transom and the section forming a water tight resilient connection.

11. In a boat, a motor'attachment member comprising a mounting section, means connectin the member to the boat'com rising a resilient watertight shock absor in material between the boat and member, an fastening means for attaching the said material separately to the boat and the attaching member.

12. An outboard motor boat comprising a driving plate having a separate motor attachment member, and means connecting the member and the plate and constituting a water-tight resilient connection there between, said means having an opposite flange overlapping the adjacent edges of the plate and member, and means separately attaching the flange to the plate and member.

, 13. In an outboard motor boat, a transom,

a motor attachment support therefor, means' forming a resilient joint there between, said means comprising interposed material having a flange overlying the adjacent edges of the transom and support, a protecting plate applied to the outer side of the flange, and means connecting the opposite edges of the late to and extending through the flange into the transom and the support.

connection to the remainder of the mounting,

and a motor oonnectedto the said portion.

5. A boat having a sectional transom, one

portion of which is resiliently connected to the remainder, and a motor mounted upon said portion.

6. An outboard motor boat comprising a transom having a portion connected to the remainder-by a resilient shock reducing joint and adaptedto support an outboard motor thereon.

7. An outboard motor having a; support ing bracket and a. boat having a'transom with i a resiliently connected water tight sectionto which the bracket is attached.

8. An outboard motor boat having a substantially vertical support with a motor 5 mounting section spaced from the remainder and means connecting the sections constituting a yielding water tight joint.

9. An outboard motor boat having a transom with a cutout section and means comprising a watertight joint .connecting the section to the remainder of the transom.
