Rick, Is their such a thing as prop-wash? If so what is it?

Sounds reasonable. To add on, would you agree
that the spinning column of water which gets
split by the rudder when going forward is then
responsible for the phenomenon called
prop-wash? I feel some pretty substantial wash

Well, this might be just the right time to float a theory I’ve had for some
time about “prop walk”. Here it is:
When the propellor is spinning, it produces a rotating horizontal column or
spinning cylinder of water molecules which move away from the propellor along
its axis. When the boat is g

Any listers have experience with this style of prop and are they 2 or 3 blade?

Martin, your situation sounds exactly like mine in regards to how extreme
the prop walk is .. I can't get the bow to point to port when there's wind
on my starboard beam, the stern just goes port etc. No combination of
punching the throttle and shifting into neutral works for me when there's

I didn't see the original post but it sounds like the prop walk is a
challenge .. it was for me too, and it continues to be sometimes (docked to
port on the windward side of a dock needing to back out). Anyway, it's
really useful sometimes .. I use the backing turn all the time! Lock the
wheel hard
Don't forget about using a floating spring line if you need to back out to
starboard.
Tie off one end of the line to your starboard stern cleat, then run it around
the rear piling and back to the cockpit.
As you are reversing, slight tension on the line keeps your stern from going to
port. Onc
There is probably some prop walk in reverse with any propeller and any boat.
I have the same issue on my 27ft. boat (with Perkins diesel).
As someone already mentioned, the only way I found to back out of the slip is
to either drive or steer, but never at the same time. Short burst of power and
While pain, take it in and out of gear and you will be fine. Prop walk can be
your friend once you learn to work with it.

You could plug your specs in here and see what the recommendation is:

I would have guessed a Gori 15X10 to be a little big, maybe the 14X9.5 is OK.
The 12X6 seems too small. If it cannot "bite" the water and stay connected
it will churn - cavitation
As i understand it, the tip to hull clearance will effect vibrations but
not prop-walk. The pitch is the leading effect on prop-walk. A larger
diameter prop will require less pitch to produce the same thrust and
subsequently less walk. Likewise a smaller prop will require more pitch
