Volvo Penta D6-300 Service and Repair for Princess V39

A client based at Brighton Marina requested assistance after their Princess V39 began displaying engine fault codes. Ocean Marine Services travelled to Brighton to investigate and, during inspection, found that the problem was more extensive than first reported. Both heat exchangers and charge air cooler end caps were leaking, an issue that could have led to serious performance and reliability problems if not resolved.

Given the scale of the required repairs and the need for specialist facilities, arrangements were made to relocate the vessel to Chichester for full servicing and repair work.

Challenges of the Project

The case presented multiple challenges. In addition to resolving the initial fault codes, the leaking heat exchangers and charge air cooler end caps needed urgent attention. The inspection and diagnosis had to be carried out on-site at Brighton Marina, which required efficient communication with the client and effective planning. The relocation of the vessel from Brighton to Chichester also had to be managed safely. Finally, with the vessel already in our care, it provided the ideal opportunity to complete a full service of both engines and gearboxes to ensure long-term reliability.

Our Marine Engineering Approach

1. On-Site Diagnostics: Travelled to Brighton Marina and connected Volvo Penta diagnostic equipment to assess fault codes.
2. General Inspection: Identified leaking heat exchanger and charge air cooler end caps, likely contributing to reduced performance and increased reliability risks.
3. Vessel Relocation: Arranged safe passage from Brighton Marina to Chichester, keeping the client fully informed at every stage.
4. Cooling System Repairs: Removed, refurbished and resealed the heat exchanger and charge air cooler end caps, preventing further water loss and restoring optimal operating temperatures.
5. Full Engine and Gearbox Service: Replaced oils, filters, impellers and belts, inspected fuel systems and serviced both gearboxes in accordance with Volvo Penta manufacturer schedules.
6. Final Testing: Conducted sea trials to confirm that all systems were operating correctly, with no further leaks or warnings.

Outcome of the Service and Repair

The Princess V39 was returned to the client in excellent running condition, with both engines and gearboxes fully serviced and the cooling system leak-free. Performance and reliability were restored to manufacturer standards, giving the vessel a clean bill of health. The client was so satisfied with the quality of service that they chose to move their berth permanently to Chichester, ensuring that Ocean Marine Services now provide ongoing maintenance and care for the boat.
