A readily mountable and removable carburetor-adjusting control harness accessory for use with a jet-propelled personal watercraft having a deck with a top engine compartment opening and a hood in sealed engagement with the deck at the periphery of the compartment opening to prevent entry of water into the Compartment, the harness having at least one coaxial structure comprising an outer casing and an inner flexible rotatable but non-twistable shaft, one end of the casing of each coaxial structure being in sealed relationship between the hood and the deck with that one end extending to the outside of the compartment when the compartment is closed by the hood, the inner shaft of each said structure extending throughout the length of the respective casing and beyond the ends of the casing, the outer manually accessible end of each shaft having a manually rotatable knob thereon for remote adjustment of a carburetor adjusting member on the other end of the shaft, a bracket structure for anchoring the carburetor end of each casing relative to a carburetor structure in said compartment to hold each said carburetor adjusting member in engagement with a respective carburetor-adjusting needle valves to adjust the valves by rotation of the knobs. Alternatively, the outer end of the coaxial harness structures may extend through an access opening in the hood and be removably attached to the hood surface. The configuration of the coaxial structures may be changed by heating the casings in boiling water, shaping them and then cooling them.
A readily attachable and detachable carburetor-adjusting fine tuning control harness for use with a vehicle having a carburetor with operator controlled throttle and at least one adjustable needle valve for fine tuning, the vehicle having a deck comprising a stationary portion and a removable hood portion which covers an engine compartment opening, said deck having an interface between the hood and the stationary deck portion at the periphery of the opening, the harness having at least one coaxial structure comprising an outer casing and an inner flexible rotatable but essentially n on-twistable shaft, one end of the casing of each coaxial structure having a releasable mounting means to secure each such end in fixed relationship to the deck at the outside of the compartment when the compartment is closed by the hood, the inner shaft of each said structure extending throughout the length of the respective casing and having ends beyond the ends of the casing, one end of each shaft being manually accessible and extending beyond said one end of the casing and having a manually adjustable knob thereon for rotating the shaft within the casing, each said shaft having a carburetor needle valve adjusting member on its other end beyond but near the other end of the casing, anchoring means for releasably securing that other end of each casing in a fixed position relative to a carburetor structure for an engine in said compartment to hold each said carburetor needle valve adjusting member in operative engagement with a respective carburetor-adjusting needle valve to adjust the valve by rotation of the knob at the opposite end of the shaft, the releasable mounting means and said anchoring means enabling separable release of said control harness as a unit relative to said deck and said carburetor structure.
A readily removable carburetor-adjusting control harness for use with a jet-propelled personal watercraft, the watercraft having a deck with an engine compartment opening and a hood in sealed engagement with the deck at the periphery of the engine compartment opening to prevent entry of water into the compartment, the harness having at least one coaxial structure comprising an outer casing and an inner flexible rotatable but essentially non-twistable shaft, one end of the casing of each coaxial structure having sealing means to provide a sealed relationship when inserted between the hood and said deck with that one end extending to the outside of the compartment when the compartment is closed by the hood, the inner shaft of each said structure extending throughout the length of the respective casing and beyond the ends of the casing, each shaft having a manually accessible end extending beyond said one end of the casing and having a manually adjustable knob thereon for rotating the shaft within the casing, each said shaft having a carburetor adjusting member on its other end beyond but near the other end of the casing, a bracket structure for releasably anchoring that other end of each casing relative to a carburetor structure for an engine in said compartment to hold each said carburetor adjusting member in engagement with a respective carburetor-adjusting needle valve to adjust the valve by rotation of a respective manually adjustable knob.
A jet-propelled personal watercraft having an engine compartment in a hull with a top opening for the compartment and a hood engaging the hull at the periphery of the opening and closing the opening with a sealed interface therebetween to prevent entry of water into the compartment, the compartment being ahead of the station typically occupied by the watercraft operator, a resilient sealing strip between the hood and said hull around the periphery of said opening, an engine means in said compartment and including tunable carburetor means therefor having a carburetor structure with at least one needle valve adjustable to tune the carburetor for optimum performance under existing environmental conditions, a readily attachable and detachable carburetor-adjusting control harness accessory, said harness having at least one coaxial structure comprising an outer casing and an inner flexible shaft, means for securely supporting one end of the casing of each said coaxial structure in sealed relationship with both the hood and said hull at said interface with that one end extending to the outside of the compartment when the compartment is closed by the hood, the inner shaft of each said coaxial structure extending throughout the length of the respective casing and beyond the ends of the casing, each shaft having a manually accessible outer and extending beyond said one end of the casing and having a manually adjustable member thereon for rotating the shaft within the casing, each said shaft having a carburetor adjusting member on its other end beyond but near the other end sing, bracket means for anchoring the other end of each casing relative to said carburetor structure in said compartment to hold each said carburetor adjusting member in a carburetor-adjusting position for adjustment of the carburetor by manual adjustment of the respective manually adjustable member at the outer end of the shaft, means for securely clamping said hood to the hull with the means for securely supporting said one end of end of each casing being clamped between the hood and the hull.
