My engine was out because I was replacing the transom assembly. I was replacing the transom assembly because aluminum corrosion was 'growing' and crushing the intake hose, restricting water flow.
It's not the size of the hose, or that it is rubber. It is simply where it is located. It's going to be very, very difficult to access with the engine in place.
'Disgusted' seems a bit extreme of an emotion for this situation. Sometime things on boats are difficult to access. My guess is you've never owned a German automobile.
