Duoprop propellers Type I

A new propeller introduced replacing the D-series. The development work and experience from the successful DPH and IPS twin -propellers has been transferred to a new aluminium propeller series with straight splines. The new Propeller series are smooth running with high comfort level. The blade geometry with thinner and larger (patented design) gives improved performance regarding acceleration, top speed and propeller grip. The design, material and its surface treatment gives a good cavitation resistance. The new series also have improved 4-layer surface treatment
including pre-treatment for corrosion protection. The I-series is recommended for boat speeds up to 38 knots (45 mph).

Note! Do not mix D series with I series on the same drive. For twin installations use only the same propellers.
