Is there a low water pickup kit for these?

The HPDI lower unit fits with a stud kit sold by HydroTec Marine. You have 1.81 gears, The HPDI LU has 1.75:1 gears. This will change your prop pitch needs, Requiring a lower pitch . It will also be slower on top end unless you are running over 82-83 mph now. The HPDI LU has less bow lift.
