Tecnoseal Volvo DPH/DPR Drive Sterndrive Engine Anode Kit

Tecnoseal KITVOLVODPH/DPR sterndrive anode kits are drive-specific replacement sets for Volvo Penta DPH and DPR installations. Zinc, aluminium and magnesium variants are available so the alloy can be matched to the vessel’s operating water and existing cathodic-protection specification.

Which Drives Are These Kits For?

Confirmed application: Volvo Penta DP-H, DPH-BP, DPH-A, DPH-B, DPH-C, DPH-D, DPH-D1, DPR-A and DPR-B sterndrives

Each variant contains the matching cavitation-plate and transom-shield anodes for this drive family. Confirm the complete drive suffix and existing anode geometry before ordering; DPH/DPR components are not interchangeable with the earlier 290/DP kit families.

What Is Included?

• Cavitation-plate anode: 1 × Tecnoseal 00733 alloy-matched component; Volvo Penta reference 3588746
• Transom-shield anode: 1 × Tecnoseal 00735 alloy-matched component; Volvo Penta reference 3588745 or 3589875
• Fixing hardware: Drive-anode fixing bolts included

How Do I Select the Correct Alloy?

Match the kit alloy to the Volvo Penta or vessel specification and to the existing anode strategy. Do not choose by weight: zinc, aluminium and magnesium have different densities even though the drive fit is the same.

Which Anode Alloy Should I Choose?

• Zinc: a conventional choice for salt-water operation.
• Aluminium: generally selected for salt or brackish water and offers lower mass than an equivalent zinc casting.
• Magnesium: generally selected for fresh water; it is normally unsuitable for prolonged salt-water use because it can be consumed too quickly.

Use the alloy specified by the vessel, drive or equipment manufacturer and keep the choice consistent with the existing cathodic-protection system. Water salinity, connected metals and stray-current conditions can change the correct selection.

Installation and Maintenance

Remove the old anode and clean the DPH/DPR cavitation-plate and transom-shield anode seats and electrical contact points to bare metal. Fit the replacement using serviceable fasteners and the equipment manufacturer’s tightening procedure. Do not paint the anode or its electrical contact surfaces.

Inspect the anode during scheduled servicing. Replace it when substantially consumed, damaged or loose, and check bonding continuity or possible stray-current faults where consumption is unusually fast or uneven.

Alloy Standards and Manufacture

Tecnoseal sacrificial anodes are manufactured in Grosseto, Tuscany. Alloy batches are checked using spectrometric analysis and produced to the applicable current US-MIL alloy specifications used by Tecnoseal for zinc, aluminium and magnesium marine anodes.

Frequently Asked Questions

• Does this fit a Volvo 290 DuoProp drive? No. The 290/DP family uses KITVOLVODP290 or a related Plus kit, not KITVOLVODPH/DPR.
• Are fixing bolts included? Yes, the Tecnoseal kit specification states that drive-anode fixing bolts are included.
• Can I order by colour or weight? No. Select by the full kit number, drive model and required alloy.
