Abstract
An oil drain system and method for draining oil for a personal watercraft that includes an oil reservoir coupled to a flow regulator, located in the interior of the personal watercraft. The flow regulator is additionally coupled to a cover that seals an access opening formed on the exterior of the personal watercraft by means of a tether such that when the cover is removed for an oil change the tether pulls the flow regulator to the exterior of the watercraft so that oil in the reservoir can be drained to the exterior of the watercraft.
Claims27
An oil draining system comprising;
- an oil reservoir having a flow regulator coupled thereto, the reservoir located in an interior of a vehicle;
- an access opening located on an exterior of the vehicle;
- a cover removably located over the access opening on the exterior of the vehicle;
- and
- a tether coupling the flow regulator of the oil reservoir to an interior of the cover, wherein when the cover is removed from the access opening, the flow regulator can be pulled through the access opening by the tether so that oil in the reservoir can be drained to the exterior of the vehicle.
A jet-propelled personal watercraft comprising;
- a hull including a bottom hull and a top deck secured over the bottom hull, the hull defining an engine compartment sized to contain an internal combustion engine for powering a jet propulsion unit, the jet propulsion unit including a steerable water discharge nozzle, the top having a raised, longitudinally extending seat adapted to accommodate an operator in straddle fashion;
- a lubricating system to lubricate the engine including;
- an oil reservoir with a drain formed therein, the oil reservoir coupled to a flow regulator;
- an access opening;
- a cover having an interior and exterior removably located over the access opening;
- and
- a tether coupling the flow regulator of the oil reservoir to the interior of the access opening cover.
A method of draining oil from a vehicle, the method comprising the steps of;
- (a) removing a cover from an access opening located on an exterior of the vehicle;
- (b) pulling the cover away from the access opening, the cover having a tether coupling the cover to a flow regulator that has an open and closed position, the flow regulator being coupled to an oil reservoir located in an interior of the vehicle, wherein the tether pulls the flow regulator through the access opening so that it is accessible from the exterior of the vehicle;
- (c) opening the flow regulator;
- (d) draining the oil through the flow regulator;
- (e) closing the flow regulator;
- (f) returning the flow regulator to the interior of the vehicle;
- and
- (g) replacing the cover over the access opening.
An oil drain system comprising;
- an oil reservoir with an oil drain formed therein;
- draining means attached at its proximal end to the oil drain;
- connecting means attached at its proximal end to the distal end of the draining means;
- and
- access opening cover means attached to the distal end of the connecting means.
