Installation Guide

1. Ensure the engine is completely cool and disconnect the boat's battery.
2. Locate the existing water cooling hose on the stern drive assembly.
3. Place a suitable container or absorbent cloth beneath the hose connections to catch any residual water or coolant.
4. Using a screwdriver or nut driver, loosen the clamps at both ends of the old hose.
5. Carefully twist and pull the hose to detach it from the fittings. Inspect the fittings for any corrosion or debris and clean them as needed.
6. Position the new hose onto the fittings, making sure it is fully seated.
7. Slide the clamps into position and tighten them securely. Do not overtighten, as this can damage the hose or fitting.
8. Reconnect the battery.
9. Once the boat is in the water, run the engine and carefully inspect the new hose and its connections for any signs of leaks.

Troubleshooting & FAQ

How do I confirm this hose fits my Volvo Penta SX stern drive?
This hose is a direct replacement for Volvo Penta part number 3852352 and is designed for SX series stern drives, including models like SX-C, SX-M, SX-R, and SX-S. Always check your original part number to ensure an exact match.
