Yeah Donal,

Prop walk it is. Scott's Sidelminn has a pretty fine, cut away stern
and bow. The Prop walk of a 3-bladed prop will spin his hull off course
very easily. He would have compensation going forward with the prop wash
going over his rudder but in reverse a real problem. The flow from his
rudder would just be fed into the Prop and used for Prop walk.

By the way, that folding Prop in your garage, is it the same size as
your original Prop?

It has the same spec. 11" x 14"(IIRC). However, it has much less
surface than the fixed prop. I was told that it had smaller blades so
that
it could fold. The blades are the same diameter when extended, but they
don't extend as far back. When I am motoring, they seem to have less
"bite".

I wonder if there are better folding props available. Perhaps, I've just
been unlucky. I will have a look the next time that I visit the Boat
Show.




On my boat I use a fixed 13x13 Std bladed and a
folding 13x13 with streamlined blades. The Folding outperforms the
fixed by a mile.except in reverse. I have to pop the RPM high enough to
open the blades and it sure does kick the stern over.

Another problem with the folding Props is sometimes there isn't enough
room between the end of the shaft and the rudder to let the blades fold.

Mine doesn't have this problem.



Regards


Donal
