I removed the old water hose at the transom assembly but how the heck do you access the Water Inlet housing behind the engine and transom to get the new hose insert screwed in? It is virtually impossible to reach your hand back there and I have yet to find a tool that will fit to unscrew the two screws on the water inlet housing. Seems that Rinker/Mercruiser would make it a little easier to change a darn water hose without having to remove an engine to get at it. Any suggestions, advice??
