Why Choose Mercury 150 TIER 3?
152HP High-Power Performance
This diesel engine produces up to 152.1 HP. Therefore, boats benefit from strong acceleration, fast planing, and stable cruising.
Tier 3 Emissions Compliance
Thanks to advanced fuel injection, this engine meets EPA Tier 3 standards. Consequently, it supports cleaner and more eco-friendly boating.
2.0L Diesel Efficiency
Because of high-pressure direct injection at 26,000 psi, fuel is burned more efficiently. As a result, fuel consumption remains low.
