Lightweight. Locked In. Ready to Launch.
The 349’s hull is built using a carbon fiber and foam-core composite, vacuum-infused with epoxy and post-cured at over 120°F for eight hours. This advanced construction method ensures an exceptional resin-to-fiber ratio and eliminates nearly all trapped air, resulting in a hull that’s stronger, lighter, and free from voids or structural inconsistencies. The vacuum infusion process delivers superior bond strength and laminate consistency, Maximum rigidity without added weight, and Long-term durability. Post curing process at 120°F for eight hours maximizes structural integrity, minimizes shrinkage after the boat leaves the factory, and delivers a perfectly hardened, lightweight form engineered for extreme performance.
The result: Explosive acceleration. Enhanced fuel efficiency. A hull with exceptional torsional rigidity. Optimized weight balance. Consistent high-speed stability. Delivering solid vibration-free performance at extreme speeds.
Race-Inspired. Confidence-Built.
Beneath that carbon shell lies a precision-engineered running surface, refined through performance testing to deliver maximum lift, stability, and control. The advanced tunnel and pad design generate substantial hydrodynamic lift, allowing the 349 to ride high and light—reducing drag, increasing speed, and maintaining high-speed efficiency. Whether you’re running wide open or cutting through offshore chop, the 349 responds instantly and confidently.
Lifts hard, runs flat, and holds its line like a missile.
Unleashed Power
The Speed Marine 349 is powered by Mercury Racing Outboards. Choose your level of performance with twin 300R , 400R, or unleash the ultimate: Twin 500R outboards for raw full throttle dominance. These engines deliver instant throttle response, class leading top-end speed, and unmatched reliability on the water. Each package is precision-matched to the hull for optimal balance, handling, and control. Whether you're chasing open water at full throttle or carving through offshore chop with confidence.
