To control the operation of the motor I by remote control as herein contemplated, means are provided for automatically adjusting and controlling the spark and gas mixture from the stop position to maximum speed. In the motor as herein shown, a single lever 1 adjusts the spark and synchronously through the use of a cam 8 simultaneously adjusts the passage of gas from the carburetor 9 to the motor I.

'As in many outboard motors, the engine is provided with a magneto fly-wheel. The ignition' system or magneto and fly-wheel are constructedas a unit, the fly-wheel l8 being mounted upon or forming part of a cup-shaped housing I i which forms with the armature plate l2 a com-- plete enclosure for the ignition system. The armature plate does not rotate with the fly-wheel l0 and housing 12, but is secured to the lever I and rotates therewith through the limited arc of movement of the lever in adjusting the spark. The complete ignition system, including the flywheel, is mounted within an external housing l3 having a depending peripheral flange M. The cup-shaped housing H and fly-wheel H) are keyed to and rotate a crank or drive shaft it which in turn rotates the propeller (not shown) for operating the boat.

Disposed at the front of the housing I3 is an elongated and arc-shaped member 13 secured to the housing by a pair of end brackets l1, IT. This member throughout the greater portion of its length forms a downwardly opening channel !8 with the rear flange 18 thereof at a point intermediate its length providing a depending lug 23 for supporting and to which is attached a pulley housing or casing 2|. At each of its opposite ends the member It provides an enclosure or housing 22 in each of which is journalled a pulley wheel 23 upon a stub shaft or pin 24. Tubes or conduits 25 connect the opposite sides of the casing 2i to the adjacent sides of the enclosures or housing 22 and these tubes or conduits are adapted to receive cables for remote operation and control of the motor. To permit ready removal of the member l8 and permit removal of the motor I for storage or assembly on another boat, the end brackets are secured thereto by winged nuts 25.

Disposed above the member i6 is the control lever I and an upstanding handle 2'! for adjusting the spark and gas supply. Generally this handle and lever are moved or adjusted manually by the operator when seated at the rear of the boat, but the present invention contemplates moving and controlling the movement of this handle and lever from the front of the boat. To accomplish this movement, an endless or continuous length of small diameter cable 28 (preferably wire of approximately 1 inch diameter) and having its ends connected by an adjustable turnbuckle 29 is securely clamped or anchored at 39 between a clamping plate 3| and the inturned end 32 of a bracket 33 having its upper end 34 secured to the handle 21 by attaching screws or.

the like 35. The end or part 36 of the cable projecting to the right of the lever I and handle 21 (see Figs. 3 and 4) passes over the pulley wheel 23, then through the tube 25 and over a pulley wheel 31 rotatably mounted within the pulley housing or casing 2|. The cable 28 then passes through one of a pair of flexible tubes 38 and over one of a pair of pulley wheels 39 journalled upon a stub shaft 40 in a housing or casing 4! (see Figs. 2 and 6), mounted in the bottom of the boat at the stern end. Next the cable passes through one of a pair of tubes or conduits 42 having one end disposed in the casing 4! and the other end in a housing or casing 43, the cable passing over one of a pair of pulley wheels 44 rotatably mounted on a stub shaft 45 in the housing or casing 43 secured in a, corner and beneath a. knee at the rear of the boat. This cable 28 then extends from the pulley 44 along one side of the boat to adjacent the forward end thereof where it passes into a housing or pulley casing 48 secured to a side of the boat adjacent the operators seat 41 and steering wheel 5. In this casing the cable 28 passes over a large pulley wheel 48 and is anchored thereto at 49. This wheel is secured upon a stub shaft 58 and pinned to the outer end of the shaft is a control handle 5|.

The section 52 of the length of endless cable 28 continues around the pulley wheel 48, over the small pulley wheel 53 and then rearwardlyalong one side of the boat and parallel to the other section of the cable where the ends are preferably connected by the turnbuckle 29. It then passes into the casing 43, over the other pulley wheel 44, other parallel tube or 42 and into the housing or casing 4!. In this casing it passes over the second pulley wheel 39, through the other or second flexible tube 38 and over the second pulley wheel 31 in the housing or casing 2|. It then passes through the other tube or conduit 25, pulley wheel 23 and anchored or clamped at 30 to the clamping plate 3! and between it and the inturned end 32 of the bracket 33.

Thus by rotating the control handle 5| and its stub shaft 50, the large pulley wheel 48 is rotated in a clockwise or counter-clockwise direction and the endless cable moves the singlelever l to the right or left to thereby advance the spark and increase the gasoline or fuel feed, or to retard the spark and decrease the feedin of the gasoline or fuel. As stated above, the single lever as shown controls both the spark and fuel supply and the latter is accomplished by providing the lever l with the cam 8 in the form of a depending bracket 54 secured to or formed on the underside of the lever. The cam face 55 is adapted to engage or contact an upstanding projection or roller 56 disposed at the outer end of an arm 51 pivotally mounted upon the upstanding shaft 58 controlling the carburetor 9. A stop 59 engages the cam face 68 on the arm 51 and limits its throw or path of movement. The carburetor may be of any suitable design and may be provided with an adjustment at SI for controlling the flow of gasoline or fuel.

It will be appreciated that the means and manner of mounting the attachment including the housing 2|, the solid, endless cable passing over a plurality of pulleys and through the flexible tubing 38, permits the outboard motor to be rotated or turned through any angle or arc required for proper steering. This flexibility of mounting and the manner of connecting the conduit 5 ea t. a

single control lever T'tothe-rernotecontrol handle further permits accurateadiustment andccone.

From; the:above-descriptionzandithe disclosure inzthe drawings. it -willlbe-readflly apparent that the present novel inventioncontrols the operation of the outboard motor by regulating and controllin the advancement and-retarding of the spark and at the same: time-controls thesu-pply of fuel to the motor. Thus the control is effective between stop position and maximum speed. Also by making the parts so that they may be quickly assembled or removed, the present novel attachment may be quickly applied or disassembled when desired.

Having thus disclosed my invention, I claim:
