I have a 1992 Four Winns with a 1992 OMC Cobra 3.0 litre. Both of my trim hoses have melted and are leaking close to the connection at the pump. Is there a fix for this other than replacing the lines? Or, if I have to replace them can I do so without removing the engine? I can see the ends of the lines at the transom, therefore if I am able to loosen the nuts will they come out? Please any help at all. Thanks
