    L Drive steering problem?

    On my 1992 120 hp L Drive, the steering is pretty tight all the way up to WOT. When I hit WOT, @5100 rpm, it loosens up a little and has lots of play in it. I have greased it in the back, where the rod comes out and turned it several times to see if that loosened it up a little, but no relief...

    Hose on an L Drive

    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...
