Genuine OEM Volvo Penta Duoprop IH-2 Rear Propeller (21661922)

Only FH and IH series propellers have the helical /spiral splines.

IMPORTANT! IH propellers are only approved on D3 diesel and 4.3L gasoline applications below 38 knots.

Note! Because of the IH Helical Spline, you cannot mix I series propellers with IH series on the same drive.

For twin installations use only the same propellers.

For all engines with speeds in excess of 38 knots, the stainless steel Type FH propeller should be used.
