An outdrive system for water craft includes in an embodiment use of plastic or other relatively flexible material, e.g., compared to metal, as a housing material, and techniques which enable and/or at least facilitate use of such housing material. Several of those techniques employ a flexible member, such as a belt, to couple power between the input and output of an outdrive, and heat conducting back bending surfaces to urge the belt legs toward each other and to remove heat from the outdrive, an anti-shear stuffer or fence to reduce energy losses such as heat, and lubricant requirements, and/or an eccentric mechanical tensioning device for the belt. The invention also relates to use in a vehicle drive, especially for water craft, of housing materials a substantial part of which are not subject to corrosion, galvanic action and the like. Other features include a rotational shock absorber system, an output shaft support, an improved sprocket tooth profile, a water by-pass silencer, an L C (analogous to an electrical inductor and capacitor filter) exhaust silencer, a split eccentric tensioner, an active tensioner, a transmission and a transmission shift mechanism, tensioning protocol and a cooling method. Also, in an embodiment the housing may be made partly or entirely of thermally conductive material, such as, aluminum, which facilitates and enhances heat removal by conduction to the water in which the outdrive is immersed.
An outdrive for a water vessel comprising an hybrid housing including a plastic portion and a heat conducting portion, at least part of the heat conducting portion constituting an exposed external surface of the housing, a chamber area in the heat conducting portion, a belt at least partly in the chamber for coupling power from an input drive to a propulsion device, the belt being at least partly in thermal transfer relation with said heat conducting portion, wherein at least part of said heat conducting portion is operatively configured to be exposed to water external of the outdrive when the outdrive is immersed.
A transmission for a water vessel drive system capable of selectively coupling power in plural operational modes, comprising
A transmission for a water vessel drive comprising:
A water vessel belted outdrive spacer for use in an ontdrive having a chamber in which at least part of a transmitting belt is located, the spacer having a configuration for positioning between legs of the belt which is at least partially immersed in fluid, the spacer displacing some of the fluid and reducing flow in the fluid.
An outdrive for a water vessel comprising a housing having a chamber, a belt which moves within the chamber for transferring power from an input shaft to an output shaft, a fluid at least partially filling the chamber, and a spacer between legs of the belt which reduces the formation of vortices in the fluid.
A rotational shock absorber for a propopulsion system of a water vessel, comprising:
A deflection limiter for a water vessel outdrive comprising a member with a shaft hole through which a shaft may protrude, and means for attaching the deflection limiter to the outdrive, wherein the means for attaching includes a collar attached to the member, the collar having holes therethrough.
An outdrive for a water vessel comprising a propeller shaft protruding from a housing, and a deflection limiter attached to the housing which limits deflection of the propeller shaft, wherein there is a clearance gap between the shaft and the deflection limiter during normal running, and wherein the deflection limiter is made of a metal and the propeller shaft is made of a different metal, the deflection limiter functioning as a sacrificial anode.
An outdrive for a water vessel comprising a propeller shaft protruding from a housing, and a deflection limiter attached to the housing which limits deflection of the propeller shaft, wherein there is a clearance gap between shaft and the deflection limiter during normal running, and wherein the housing is a hybrid housing including a plastic portion, and the deflection limiter attaches to and is structurally supported by hybrid housing.
An outdrive for a water vessel comprising a belt which moves within the chamber for transferring power from an input shaft to an output shaft, and a preload device for adjusting tension in the belt, the preload device including a wheel which engages the belt, and a carrier operatively coupled to the wheel, an outer surface of the carrier being eccentric with an inner surface of the carrier, rotation of the carrier causing a center of the wheel to move, thereby adjusting tension in the belt.
An outdrive for a water vessel comprising a belt which moves within a chamber for transferring power from an input shaft to an output shaft, and an active tensioner which actively adjusts the tension of the belt, wherein the active tensioner includes a device having a set of back benders slidably in contact with both legs of the belt, the device operatively configured to laterally translate relative to the belt.
A muffler for an internal combustion engine for marine use, the muffler comprising:
A muffler for an internal combustion engl for marine use, the muffler comprising:
A muffler for an internal combustion engine for marine use, the muffler comprising:
A mnuffler for an internal combustion engine for marine use, the muffler comprising:
