of the adaptor 4 on the outside of the reservoir 1 a shut off valve 6 is threaded onto the adaptor 4 and tightened a 5 39 to 8 39 long 5 8 34 garden hose 7 is included that can be threaded onto the shut off valve 6 this transports water from the reservoir 1 to a commercially produced motor flush unit that attaches to the water intake at the lower unit of the marine engine a lid 8 is placed on the five gallon reservoir 1 during transportation when filled with water as stated earlier this unit is portable due to the fact that gravity is the power source it does not rely on electricity or external sources of water pressure to operate it relies on gravity flow to force the water into the impeller of the water pump of the marine engine also water is transported in the reservoir to the location of the engine initially the shut off valve is closed and the reservoir is filled with fresh water the lid is then put snugly on the reservoir and the reservoir is transported to the location of the marine engine the reservoir is then placed on a flat surface substantially higher than the water pump of the engine one end of the 5 8 garden hose is screwed onto the shut off valve of the reservoir and the other end is screwed onto the flush unit that has already.
