What is Prop Slip?
Pitch is the distance the propeller/boat progresses thru the water in
one complete turn. Every inch of boat that's in the water induces drag,
and therefore the distance traveled is not always the same. This results
in the propeller "slipping" behind the theoretical distance it should
travel with each rotation. The difference between theory and reality is
called "propeller slip".
How it works...
Inside the DataTach™ is a computer that receives GPS speed & RPM info and it calculates the
slip of your boats propeller. It does this 5 times per second, to give
you an
accurate reading. See the equation below.
|
Slip=
speed (MPH) x
1056 x drive ration x 100 |
|
RPM x pitch(in) |
A few things that
affect prop slip
- pitch of propeller
- propeller size
- condition of the bottom of the boat
- condition of the propeller
- weight distribution
- engine mount height
- jack plate mounting
- trim angle
