DPS-A, size "I4", Aluminium Duoprop propeller set.
This is a genuine I4 size Duo-prop set of propellers for the DPS and DPS-A Sterndrive. The patented blade geometry and large active propeller diameter provide optimal performance and fuel efficiency over the entire speed range as well as smooth running, excellent grip and manoeuvrability. Squeeze casting and special high-strength aluminium alloy make them stronger and more durable than traditional die-cast propellers.
If your existing "D" set is badly pitted or corroded, then it's time to consider changing your props to this new Type I design before they fail.
If you are changing from the "D" series to the new Type I series, D4 corresponds to an "I4" propeller set. Obviously, D series and "I" propellers must not be mixed on any installation. Type I has straight splines, and type "IH" has helical splines only suitable for the DPS-B Sterndrive. For engines with speeds in excess of 35 knots or 240HP, the stainless steel Type F propeller should be used.
Genuine Volvo Penta propellers are covered by our standard 12-month warranty. If installed by us or another authorised dealer, we will extend your warranty to 24 months.
Type "I" is the alloy propeller type for a DPS and DPS-A Sterndrive, and 4 is the size of the Duoprop set. The existing size should be stamped into your existing props. If you need help sizing the correct size for your boat, please contact us first.
