Rebuilding a PRO XS DFI Opti Mercury 3.0 or 3.2 Liter Stroker outboard with our new piston kits is key to restoring high performance and reliability, especially for racing and high-performance use.
- Restore Performance: Worn pistons reduce power and efficiency. New kits can restore compression, making your outboard run like new.
- Improve Fuel Efficiency: Old pistons cause poor combustion and higher fuel use. Rebuilding improves efficiency, saving on fuel costs.
- Prevent Failures: Worn pistons can crack or seize, risking engine damage. New pistons enhance reliability in high-stress conditions.
- Increase Durability: Advanced coating materials in our kits reduce friction, extend engine life, and handle the demands of racing.
- Reduce Emissions: New pistons improve combustion, lowering emissions and meeting environmental standards.
- Cost-Effective: Rebuilding can be less expensive than a new engine, offering near-new performance at a fraction of the cost.
- Enhance Performance: New piston kits can boost horsepower and acceleration, ideal for high-performance and racing outboards.
