Abstract: The remote start control system may include at least one vehicle device associated with starting an engine of the vehicle, a remote start transmitter, and a vehicle remote start controller connected to the data communications bus for communicating with the at least one vehicle device associated with starting the engine of the vehicle. The remote start controller may be responsive to signals from the remote start transmitter. The vehicle device associated with starting the engine of the vehicle may include at least one controller, such as the engine management controller or the transmission controller, for example. Alternately, or additionally, the at least one vehicle device associated with starting the engine of the vehicle may include at least one vehicle sensor. For example, the vehicle sensor may be one or more of a brake sensor, a transmission sensor, a hood sensor, or an engine speed sensor. The remote start system may also include features to provide compatibility with a number of different vehicles.

Abstract: An airboat propelling system is provided wherein a propeller is rotated by a hollow driven shaft. A further embodiment is provided wherein two propellers are rotated in opposite directions by counter-rotating coaxial hollow driven shafts. Floating stiffener bearings positioned between the coaxial hollow driven shafts suppress flexion and protect the opposing surfaces of the shafts. These innovative techniques permit a minimization of size and weight, as well as a reduction in rotational speed of the propellers, maximizing efficiency and decreasing noise.
