Abstract

An apparatus that facilitates the filling of a marine engine lower unit reservoir with gear lube. A squeezable container having a conical spout with a threaded base is modified by cutting off a substantial part of the spout, leaving only a truncated, unthreaded part above the threaded base. The threads at the base of the spout engage complementally formed threads in a fitting member having an axial bore disposed in fluid communication with a first end of an elongate flexible tube that carries a clamp member operable to selectively open and close the tube to fluid flow. The opposite end of the tube is confluent with an axial bore formed in another fitting that is adapted to engage either a drain opening or a vent opening in a lower unit. The lower unit is filled by elevating and inverting the squeezable gear lube container when the clamp is open and the proper fitting is engaged with the drain opening. The clamp is closed when an empty tube is removed and a new squeezable tube is engaged with the fitting having the swivel head. The clamp is reopened and the process is repeated until the required amount of gear lube has been introduced into the engine outdrive. The same apparatus also has utility in connection with draining and flushing the lubrication reservoir.
