first thing, before ordering up a fix, is to find out what the noise is. just poke your head in and follow the steering cable from stem to stern to find the noise. may just be to cables rubbing each other in an odd way. one of our boats makes a noise like rubbing on guitar strings sometimes.
after you trace the cable to the rear, remove the steering drum cover and check to see that everything is kosher. have a buddy work the steering while you investigate.
i know this sounds elementary, but find out what is really going on before dropping off with the dealer.
