US3931828A — Flushing accessory for outboard motors

Claim 1

Independent Claim 153 words

A self-gripping flushing accessory quickly attachable to and detachable from the cooling water intake openings of an outboard marine engine without need for tools or fasteners while flushing the engine cooling passages, said accessory having a U-shaped main body equipped between the free ends of the legs thereof with resilient sealing means facing toward one another, at least one of said resilient sealing means being provided with a water flow passage readily connectable to a source of water, said U-shaped main body being sized to straddle the engine drive shaft housing with the legs of said main body holding said resilient sealing means seated over a respective one of said cooling water inlets with a snug substantially water-tight self-gripping fit whereby the engine water circulating pump is operable to circulate cooling and flushing water through the engine cooling passages without need for submerging said engine cooling water inlets in a body of water.

Claim 2

Dependent Claim 153 words

A self-gripping flushing accessory quickly attachable to and detachable from the cooling water intake openings of an outboard marine engine without need for tools or fasteners while flushing the engine cooling passages, said accessory having a U-shaped main body equipped between the free ends of the legs thereof with resilient sealing means facing toward one another, at least one of said resilient sealing means being provided with a water flow passage readily connectable to a source of water, said U-shaped main body being sized to straddle the engine drive shaft housing with the legs of said main body holding said resilient sealing means seated over a respective one of said cooling water inlets with a snug substantially water-tight self-gripping fit whereby the engine water circulating pump is operable to circulate cooling and flushing water through the engine cooling passages without need for submerging said engine cooling water inlets in a body of water.

Claim 3

Dependent Claim 34 words

An engine flushing accessory as defined in claim 1 characterized in that said U-shaped main body is formed in one piece from rigid resilient material with the legs thereof generally parallel to one another.

Claim 4

Dependent Claim 51 words

An engine flushing accessory as defined in claim 1 characterized in that said resilient sealing means provided with said water flow passage includes one part of a two-part separable hose coupling to facilitate connecting the water passage of said accessory to a source of water via a hose or the like.

Claim 5

Dependent Claim 52 words

An engine flushing accessory as defined in claim 1 characterized in that said U-shaped main body is resilient and shaped to hold said resilient sealing means firmly pressed against the opposite surfaces of the engine propeller shaft housing and adjacent the portions thereof surrounding the adjacent one of said cooling water inlets.

Claim 6

Dependent Claim 137 words

An engine flushing accessory installable without need for tools or fasteners over the dual cooling water inlets of an outboard motor and adapted to be held temporarily and frictionally assembled thereto while the engine is being operated out of the water, said accessory comprising a U-shaped main body of rigid material, sealing means of elastomeric material mounted between the free ends of the legs of said main body and cooperable therewith to hold said accessory frictionally and firmly assembled astride the engine propeller shaft housing with said sealing means covering a respective one of said water inlets and firmly gripping the juxtaposed surface of said housing, and one of said sealing means including a water flow passage connectable to a source of water thereby to supply water to the engine while being operated out of the water.

Claim 7

Dependent Claim 137 words

An engine flushing accessory installable without need for tools or fasteners over the dual cooling water inlets of an outboard motor and adapted to be held temporarily and frictionally assembled thereto while the engine is being operated out of the water, said accessory comprising a U-shaped main body of rigid material, sealing means of elastomeric material mounted between the free ends of the legs of said main body and cooperable therewith to hold said accessory frictionally and firmly assembled astride the engine propeller shaft housing with said sealing means covering a respective one of said water inlets and firmly gripping the juxtaposed surface of said housing, and one of said sealing means including a water flow passage connectable to a source of water thereby to supply water to the engine while being operated out of the water.

Claim 8

Dependent Claim 37 words

An accessory as defined in claim 5 characterized in that said sealing means with a water flow passage is cup-shaped with the concavity thereof facing toward the adjacent surface of the other one of said sealing means.
