A marine motor assembly for mounting to a watercraft is disclosed. The marine motor assembly has a motor unit including a motor unit housing, a motor, a propulsion device, an air pump fluidly communicating with an under-housing volume of the motor unit housing, a pressure sensor for measuring air pressure in the under-housing volume, and a control unit communicating with the air pump and the pressure sensor. The control unit is programmed for controlling the air pump for changing air pressure in the under-housing volume, and monitoring change in the air pressure for a predetermined amount of time for confirming that the motor unit housing is water-resistant, or that the water resistance of the motor unit housing is compromised. A method for testing a water resistance of a motor unit housing of a marine motor assembly is also disclosed.

A tiller system for a marine outboard engine having a tiller bracket is described. The tiller system comprises a tiller for mounting to the tiller bracket. A speed input control is mounted to the tiller and a speed input control position sensor detects a position of the speed input control. A control unit is mounted to the tiller and is operatively connected to the speed input control position sensor. The control unit converts the position of the speed input control into a speed input message. A digital communication port of the control unit transmits the speed input message to the marine outboard engine over a controller area network bus. A marine outboard engine having the tiller system and a marine outboard engine system for a watercraft are also described.

A tiller assembly includes a base and a tiller arm pivotably connected to the base. One of the base and the tiller arm defines a recess. The recess is at least partially defined by a female tapered surface. A shaft extends through the base and the tiller arm and has a first threaded portion. A clamping fitting is connected to the shaft and received in the recess. The clamping fitting is rotationally fixed relative to another one of the base and the tiller arm and has a male tapered surface. One of a handle and the clamping fitting has a second threaded portion engaged with the first threaded portion. Rotation of the first threaded portion relative to the second threaded portion in a pre-determined direction causes the male tapered surface to press against the female tapered surface. A marine outboard engine and a tiller assembly kit are also provided.

A tiller system has a tiller adapted for steering at least one of a bracket assembly and a motor assembly of a marine outboard motor having a power steering system, a throttle control mounted to the tiller, an electronic torque sensor, and a tiller system control module (TSCM) in electronic communication with the electronic torque sensor. The electronic torque sensor senses torque applied to the tiller and outputs an electronic steering signal as a function of the torque. The TSCM receives the electronic steering signal and controls an operation of the power steering system in response to the electronic steering signal. A method for steering a marine outboard motor, and a marine outboard motor having a tiller system are also described.

An internal combustion engine has at least two exhaust ports and a valve assembly. The valve assembly has first and second connectors, first and second actuator pistons connected to their corresponding connectors, the first and second actuator pistons being disposed in first and second chambers respectively, and first and second valves connected to their corresponding connectors. The first connector, actuator piston and valve are movable together between first and second positions. The second connector, actuator piston, and valve are movable together between first and second positions. A first fluid line supplies hydraulic fluid in the first and second chambers on a first side of the first and second actuator pistons. A second fluid line supplies hydraulic fluid in the first and second chambers on a second side of the first and second actuator pistons. At least one fluid pump supplies hydraulic fluid to the first and second fluid lines.

A cellular telephone holster includes a holster section formed to accept a cellular telephone. A clip portion is rotatably attached to the holster section and formed to have a circular opening with at least one detent along an inner perimeter of the opening. A spring system is coupled to the holster section and includes a substantially incompressible piston and a compressible material separate from and coupled to the substantially incompressible piston. The circular opening is sized to fit around the spring system. The holster section is formed to have at least one protrusion, and the substantially incompressible piston and the compressible material are insertable against the protrusion, whereby the at least one protrusion contributes to holding the substantially incompressible piston and the compressible material in place relative to the holster section.

An integrally molded clip (,) and clip assembly (,) has a back (,), a front (,), a bridging member (,) and spigot guide tracks (,). Front (,) has a socket (,) and a locking member (,) that is biased to a spigot locking position and having a free end providing part of a side wall (,) of socket (,). Locking member (,) is pivotal about a pivotal axis (,) provided by a pivotal mount (,) on front (,) and has a lock release member (,) extending away from socket (,). A protrusion (,) in socket (,) is biased by a rib (,) to engage one of slots (,) on a spigot (,) that enables different locking positions of a portable electronic device using assembly (,). The device is rotatable when spigot (,) is engaged with socket (,) and detachable from clip (,) when a user actuates lock release member (,).
