An apparatus for enabling the testing of an inboard marine engine on dry land has a water reservoir 11 for containing a predetermined volume of water having at least one water inlet aperture 20A and at least one water outlet aperture 31 set in the or a reservoir wall 13; the water inlet aperture 20A is connected to a water supply by means of a connector 20; the water outlet aperture 31 incorporates a relief valve 30 for limiting the release of excess water pressure through the outlet aperture 31; the reservoir 11 is open at the top with a flexible waterproof seal 17 situated around its rim for creating a waterproof seal between the rim and an undersurface of a marine vessel hull 50 adjacent a water pump inlet 51 of the marine engine; when in use the water contained within the reservoir 11 is drawn into the engine cooling system by a water pump through the water pump inlet 51 situated in the hull of the vessel and a vacuum pressure is created in the reservoir 11 which maintains the waterproof seal between the rim and vessel undersurface 50, and the volume of water within the reservoir 11 available for drawing up by the engine cooling system water pump is kept constant when in use by the water supply to the reservoir 11 and the release of excess water pressure through the relief valve 30 especially when the engine is not engaged.
