Bluewater 25T Power Comparison: Twin V6 200s vs. Single V10 400
Published April 11, 2025

At Center Consoles Only, we're committed to providing real-world testing to inform your boating decisions. In collaboration with Bluewater Boats and Mercury Marine, we conducted a side-by-side comparison of two nearly identical Bluewater 25Ts—one equipped with twin V6 200s and the other with a single V10 400. This analysis offers valuable insights for those considering the best power configuration for their maritime adventures.
Performance Metrics:
Twin V6 200s:
- Top Speed: Approximately 50 mph
- Cruising Speed: 30 mph at 4,000 RPM
- Fuel Efficiency: 2.3 mpg at cruising speed
- Acceleration: 0 to 30 mph in 9.1 seconds
Single V10 400:
- Top Speed: Approximately 52 mph
- Cruising Speed: 30 mph at 4,000 RPM
- Fuel Efficiency: 2.5 mpg at cruising speed
- Acceleration: 0 to 30 mph in 8.5 seconds
Note: These figures are based on our testing conditions and may vary with load and sea state.
Handling and Maneuverability:
During our tests, the single V10 400 setup demonstrated slightly better acceleration and fuel efficiency, while the twin V6 200s offered enhanced redundancy and stability, particularly in offshore conditions. As mentioned in the video:
"The single V10 400 surprised us with its quick throttle response and impressive fuel economy, making it a compelling choice for those prioritizing efficiency."
Conversely, the twin setup provided a sense of security:
"Having two engines gives you that extra peace of mind when you're miles offshore."
Maintenance and Cost Considerations:
- Twin V6 200s:
- Higher initial cost due to two engines
- Increased maintenance requirements
- Offers redundancy in case of engine failure
- Single V10 400:
- Lower upfront cost
- Simplified maintenance
- Slightly better fuel economy
Conclusion:
Both configurations have their merits. The twin V6 200s are ideal for those who prioritize redundancy and stability, especially for offshore excursions. The single V10 400 offers a modern, efficient alternative without compromising on power. Your choice ultimately depends on your boating priorities and how you intend to use the Bluewater 25T.
