us in flat water at about 3000 rpm. The Gori has square blades and not the e=
lliptical that the Martec has and is also a geared prop, the backdown is twi=
ce as good as a Martec. Heartbeat had a 16=E2=80=9D Max prop and you can adj=
ust the pitch to whatever you desire. You will need to shorten the tapered e=
nd about an inch to accommodate the Max prop nut. Hope this helps. Non
