Yamaha and Mercury Outboard Repower Options
We are proud to provide industry-leading propulsion options from the two most trusted names in marine engineering. Whether your hull was built for absolute top-speed performance or quiet, efficient coastal cruising, we have the ideal power match in our facility.
Yamaha Outboards: Reliability Meets Innovation
Yamaha Marine engines are legendary throughout the Lowcountry for their bulletproof reliability and smooth, quiet operation. Upgrading to a modern four-stroke digital Yamaha brings advanced features like digital electronic steering and unmatched fuel management systems. These platforms are a perfect match for premium center consoles and dual consoles, providing the dependable torque needed to navigate coastal inlets safely.
Mercury Outboards: Cutting-Edge Power and Acceleration
Mercury Marine has redefined modern outboard performance with its line of lightweight, high-displacement powerheads. Known for blistering hole-shots and incredible power-to-weight ratios, a new Mercury outboard turns any older vessel into an agile, high-performing machine. With advanced digital throttle and shift options, maneuvering your vessel at the dock becomes completely effortless.
Signs Your Current Boat Motor Needs an Upgrade
Many boaters in Summerville and Hilton Head Island wonder whether they should continue fixing an aging engine or make the switch to a new powerplant. If you are experiencing any of the following issues, upgrading your outboard is likely the most cost-effective path forward:
- Escalating Repair Costs: When annual maintenance bills begin approaching the actual value of the motor, investing in a modern engine with a fresh factory warranty makes financial sense.
- Poor Fuel Economy: Older two-stroke and early four-stroke engines consume significantly more fuel than modern high-tech blocks.
- Unreliability and Chronic Stalling: If you no longer feel confident taking your family or friends away from the dock, it is time to upgrade your propulsion system.
- Lack of Modern Tech Integration: Older outboards cannot communicate with modern GPS, digital displays, and joystick piloting systems.
