I do not agree with the SS Prop at all. A SS Prop is
probably the worst thing you can put on your stern drive. If
you hit something in the water the prop will no give like an
alum. will and it causes a lot of shock on the lower unit
gears. SS no good. The boat hull design has a lot to do with
the performance and cavitation. It may be a problem you just
might have to live with.

When cruising with my merc 5.0 alpha 1 on my 22 ft Sea Ray
EC, I
occasionally experience what I think is cavitation when
encountering rough
or choppy water at speeds around 35 mph. To get out of this
condition,
adjusting the trim has little effect and sometimes it is
necessary to come
off plane. I know there are some devises that can be
attached to the
outdrive to help with this. Does anyone have any experience
with this that
could perhaps recommend a solution?

When I refer to cavitation, the condition causes an increase
in RPM and a
decrease in speed and is caused by the prop is not making
proper contact
with the water, due to too much air around it.
