Kmoose is referring to the cubic inch displacement of the helm pump itself.
1.7 cubic inch is pretty standard. That's what I have (I think...).
Should say on the back of the helm somewhere.
Here's a listing on the seastar website (at the bottom) of all the helm pumps, their displacements and part numbers.
