Boat steering squeals when I turn the drive all the way to the side,?

Question

It seems like it might be going past the locked position. I made sure that the system was bled and nothing changed. it is a 03 volvo penta.

Answer 1

If it's a belt driven pump it may just be low on fluid.

Answer 2

You are probably hearing the system bypass valve when you bottom out the steering cylinders.  Or, if it's a belt driven pump you may be hearing the belt slip under the extra load.
