I have a 1992 120 hp L Drive and I am wondering if it is a bad thing that the giant "Ribbed" hose on the lower unit is cracked? It has a couple small cracks from dry rot in it and when I pull it out of the water or after I run it on the muffs, water drips out really slow for a minute or two. Could this be sucking water in? Would that cause performance problems? I hope not because it is a $170 hose new!! Thanks!
