Duoprop propellers Type IH
The new IH-series have the same benefits as Type I but is specially made for the DPS-B drives with helical splines. Only FH- and IH-series propellers have the helical splines. The IH-series is the aluminium option for the DPS-B drive. Important! IH propellers are only approved on D3 diesel and 4.3L gasoline applications below 38 knots (45mph)
