Piggyback Auxiliary Motor Bracket

U.S. Patent : Pending

Inventor : William Cribbs

The present invention relates generally to water craft and, more specifically, to water craft having an outboard motor with an auxiliary motor attached thereto by means of the bracket of the present invention. The bracket has an auxiliary motor mounting plate with divergently extending arms to receive the body of the outboard motor and fixed thereto. A third arm extends from the mounting plate extending downwardly and is also fastened to the outboard motor. Additionally the reason the auxiliary motor can be mounted rigidly is that the main motor has a five inch longer shaft, allowing the auxiliary motor to be mounted so when in a plane the auxiliary motor is out of the water, and when dropped down from a plane, it is deep enough to prevent cavitation. Also the depth is set by the trim on the main motor.

FIGURE 1
FIGURE 1 is an illustrative view of the auxiliary motor mount 10 in use. The present invention is an auxiliary motor-mount bracket 10 for the attachment to a boat's main outboard motor 12. The auxiliary motor 10 is rigidly mounted to the main motor 12 and allows operation by the boats 20 steering wheel and auto pilot, rendering its operation hands free. The auxiliary motor 14 operates off the main fuel tank through a fuel line switch. The auxiliary (piggy back) motor 14 does not affect the performance of the boat and is used as a backup motor and a trolling motor. The reason the auxiliary motor 14 can be mounted rigidly is that the main motor 12 has a five inch longer shaft, allowing the auxiliary motor 14 to be mounted so when in a plane the auxiliary motor is out of the water, and when dropped down from a plane, it is deep enough to prevent cavitation. Shown is the main motor mounting bracket 10 for an auxiliary motor comprising a pair of main mounting arms 16 for fastening the bracket 10 to the main motor 12 and an angled arm support 18 for attachment to the motor shaft. Also shown are a pair of angle-bracket stabilizer arms 22 which are fastened to the angled arm support 18 channel-bracket 24 and the auxiliary motor cavitation plate. Also the depth is set by the trim on the main motor 12.

Illustrated is the main motor mounting bracket 10 for an auxiliary motor comprising a mounting plate 17 having a pair of main mounting arms 16 dependingtherefrom for fastening the bracket 10 to the main motor 12 and an angled arm support 18 for attachment to the motor shaft. Also shown are a pair of angle-bracket stabilizer arms 22 which are fastened to the angled arm support 18 channel-bracket 24 and the auxiliary motor cavitation plate. A plurality of mounting recesses 26 are disposed on the various arms and brackets.

FIGURE 3 is a top view of the auxiliary motor mount 10. Shown are the main mounting arms 16 and the angled arm support 18extending from the main mounting plate 17 and the angle bracket stabilizer arms 22 secured to the channel bracket 24 of the angled arm support with bolts 28 passing through their respective mounting recesses 26. A screw 30 is provided for the mounting recess 26 to the shaft housing. The auxiliary motor rigidly mounted to the main motor allows operation by the boat's steering wheel and auto pilot, rendering it operation hands free. The auxiliary motor operates off the main fuel tank by incorporating a fuel line selector switch for either motor.

FIGURE 6 is a perspective view of the present invention 10 ready to be mounted to a boat's main motor 12. The present invention provides an auxiliary motor bracket 10 mountable to a main motor 12 whereby an auxiliary motor can be rigidly mounted thereto and function in similar fashion has the main motor 12 using the main motor steering system and fuel line by incorporating a fuel line selector switch for either motor. In addition to serving as a backup motor the auxiliary can serve as a trolling motor.

FIGURE 7 is a perspective view of the auxiliary motor mount 10 attached to a boat's main motor 12. Shown is the auxiliary motor bracket 10 for the attachment to a boat's main outboard motor 12 of an auxiliary (piggy back) motor of smaller size. The auxiliary motor mounted to the main motor 12 allows operation by the boats steering wheel and auto pilot, rendering its operation hands free. The auxiliary motor operates off the main fuel tank. The auxiliary (piggy back) motor does not affect the performance of the boat and is used for a backup motor and a trolling motor.
