Overview: SP/DP drive series
Volvo Penta SP and DP drives belong to the classic Sterndrive systems with Z-drive. They combine engine power with a compact, high-torque drive train that efficiently transfers propeller power into the water. Spare parts for these systems cover both engine-related and drive-related components.
Gaskets & Seal Kits
Z-drive systems require reliable seals and complete seal kits to:
-
Prevent water and oil ingress
-
Keep bearing areas dry
-
Securely seal transitions between housings and flanges
Seals vary depending on the year of manufacture, series and drive variant, so matching by reference number is crucial.
Bearings, shafts & mechanical components
Mechanical integrity includes
-
Shaft bearings & needle bearings - secure rotating elements
-
Propeller shaft seals - prevent water and lubricant leaks
-
Bearing housing components - for stable drive bearings
These components contribute to smooth running, durability and performance.
Bellows, hoses & exhaust parts
SP/DP spare parts also include
-
Bellows for exhaust systems - flexible transitions, sealing against water ingress
-
Hydraulic and cooling water hoses - safe conduction of media
-
Exhaust hoses & exhaust pipes - for correct exhaust gas routing
Bellows protect sensitive areas and contribute to the reliability of the overall system.
Hydraulics & trim systems
Hydraulic and trim system parts for SP/DP drives include:
-
Trim pumps & cylinders
-
Hydraulic hoses & connection components
-
Sensors for trim and angle measurement
These components support precise trim movements and optimum driving performance.
Selection by reference number & year of manufacture
The reference number is the most reliable way to correctly assign SP/DP spare parts, even if the year of manufacture and small model variants differ. Differences in diameter, hole pattern, seal contour or bearing dimensions can have a decisive influence on function.
Recommended procedure:
-
Check the reference number of the old part
-
Determine year of manufacture & drive variant
-
Select the right spare part
This structured selection reduces incorrect orders and installation problems.
Installation & maintenance instructions
Please note when replacing or maintaining SP/DP spare parts:
-
Remove old seals completely
-
Clean the housing and bearing surfaces
-
Insert new seals/O-rings correctly
-
Observe torques and assembly specifications
-
Bleed the hydraulic system and check the function
Careful assembly reduces the risk of failure and extends service life.
