The present invention is directed to a mounting device for a fish finding apparatus and, more particularly, to a motorized mounting device which includes an adjustable length pole used to mount a sonar transducer or other device an angler may be interested in mounting to the end of the pole that enters the water. The pole is used to spin the transducer or other apparatus in a clockwise and counterclockwise direction with a switch that is adapted to be operated by the angler's foot or a wireless remote. The mounting device is configured to be secured to a boat or mounted on a boat troll motor whereby the adjustable pole is secured and spins independent of the troll motor shaft.

An outboard motor that controls combustion in an engine according to a purification rate by a catalyst and is capable of performing efficient engine combustion. The outboard motor includes a catalyst provided in an exhaust manifold of an engine and a second catalyst provided in an exhaust pipe, an air-fuel ratio sensor and an O2 sensor, which are located on an upstream side and a downstream side of the catalyst, respectively, and a controller for controlling combustion in the engine. The controller calculates an exhaust gas purification rate based on a value detected by the air-fuel ratio sensor or the O2 sensor and controls the combustion in the engine so as to make the exhaust gas purification rate appropriate.

A marine propulsion system includes an outboard motor including an outboard motor engine, a propulsion generator to be driven by the outboard motor engine, and an electric starter to start the outboard motor engine. The outboard motor is installed on a hull, and an outboard motor capacitor is provided in the outboard motor to supply to the starter power to start the outboard motor engine. The outboard motor capacitor has a higher output per unit volume than a lead storage battery.

A marine propulsion system includes an outboard motor installed on a hull and including an engine to drive a propulsion generator, and a generator to generate power by driving of the engine, a capacitor provided in the outboard motor to smooth the power generated by the generator and output the smoothed power to a device on a hull side, and a power distributor provided in the outboard motor to limit an output from the capacitor to the device on the hull side.

The trolling motor releasable mounting bracket system is for trolling motors (e.g., GPS guided trolling motors), includes its own power plug within the assembly, and is configured to mount a trolling motor to a vessel deck. The system includes a motor bracket and a vessel bracket. The motor bracket includes a receiving section to slidably receive the vessel bracket therein. The motor bracket further includes a motor power cord section including a motor power cord channel configured to route a motor power cord and secure an associated motor power connector therein. The vessel bracket includes a vessel power cord section including a vessel power cord channel configured to route a vessel power cord and secure an associated vessel power connector therein. And, the motor power cord channel and the vessel power cord channel are configured to align the respective motor power connector and the vessel power connector, for automatic connection, upon the vessel bracket being slidably received in the receiving section of the motor bracket.

Stabilizer is provided for joining parallel shafts in a marine environment and including a split bushing to permit one shaft to move rotationally and longitudinally relative to the stabilizer.

A marine engine has a powerhead, a crankcase and a crankshaft disposed in the crankcase. A cooling system has a cooling passage that conveys cooling water for cooling the crankcase, a pump that pumps the cooling water from a body of water in which the marine engine is operated through the cooling passage, and a valve that controls discharge of the cooling water from the cooling passage.

An outboard motor includes a trolling mode. The outboard motor includes an outboard motor body including a propeller and a drive source, a tiller handle body extending forward from the outboard motor body, a grip handle extending from a front end surface of the tiller handle body and configured to steer the outboard motor body via the tiller handle body, and a trolling switch attached to the tiller handle body and configured to adjust a trolling speed. An operation portion of the trolling switch is attached to a lower front end surface of the tiller handle body, the lower front end surface being located below the grip handle.
