2007 Grady-White Marlin 300 - Twin 2021 Suzuki 300s - Bow Thruster - Updated Generator & Electronics
2007 Grady-White Marlin 300 - Twin 2021 Suzuki 300s - Bow Thruster - Updated Generator & Electronics
This 2007 Grady-White Marlin 300 is a significantly updated example of one of Grady-White's most versatile offshore express models. Powered by twin 2021 Suzuki 300 HP four-stroke outboards with very low hours, she combines 600 total horsepower with the offshore capability, substantial cockpit and overnight accommodations that have made the Marlin 300 a popular platform for both serious fishing and recreational cruising.
This boat has benefited from considerable recent investment, including the 2021 Suzuki repower, a generator that is approximately one year old, recent electronics, autopilot, updated electrical equipment and underwater lighting.
She is also equipped with a bow thruster, outriggers, air conditioning and a well-appointed cabin, creating a boat that is equally capable of heading offshore for the day or accommodating extended weekends on the water.
TWIN 2021 SUZUKI 300s - VERY LOW HOURS
Power is provided by twin 2021 Suzuki 300 HP four-stroke outboards producing a combined 600 HP.
The newer Suzuki power is one of the most significant features of this particular Marlin. Rather than relying on engines dating back to the boat's original 2007 build, she benefits from significantly newer four-stroke propulsion with very low hours.
For a buyer comparing older offshore express boats, the combination of a proven Grady-White platform and 2021 Suzuki power deserves particular attention.
A bow thruster provides additional maneuverability around the dock, making a substantial 30-foot express boat considerably easier to position in close quarters.
UPDATED SYSTEMS & EQUIPMENT
The investment in this Marlin extends beyond the engines.
The generator is approximately one year old, providing an important systems upgrade for owners planning to spend extended time aboard or operate cabin amenities away from shore power.
The boat also features recent electronics, autopilot and updated electrical equipment, along with underwater lighting.
Together with shore power, air conditioning and hot water, these improvements add meaningful functionality for both cruising and overnight use.
OFFSHORE FISHING & COCKPIT
The Marlin 300 was designed to combine genuine offshore fishing capability with the protection and accommodations of an express cruiser.
A large cockpit provides the working space needed for fishing while remaining equally useful for entertaining and recreational days on the water.
Outriggers add to the boat's offshore fishing capability, while the hardtop provides protection at the helm and contributes to a more comfortable operating environment during longer days on the water.
The walkaround configuration provides convenient access around the boat and forward to the bow, whether handling lines, anchoring or moving around the vessel while underway.
An anchor windlass further simplifies anchoring duties.
CABIN & ACCOMMODATIONS
Below deck, the Marlin provides the amenities necessary to turn an offshore fishing platform into a genuine weekend boat.
The cabin offers comfortable accommodations for overnight trips along with air conditioning for climate-controlled comfort. A flat-screen TV provides onboard entertainment while relaxing below deck.
The galley is equipped with:
- Refrigerator
- Stove
- Microwave
- Hot water
A marine head adds another important level of convenience for longer days and overnight stays.
With a 32-gallon freshwater capacity, shore power, generator and onboard climate control, this Marlin offers the systems and accommodations needed to comfortably extend time aboard beyond a typical day trip.
HELM & NAVIGATION
The helm is equipped for serious time on the water, with recent electronics complemented by:
- GPS/chartplotter
- Autopilot
- VHF radio
- Bow thruster
- Updated electrical equipment
- Anchor windlass
- Radar system - currently not operational and requires replacement
The existing radar is not currently operational and will need to be replaced by the next owner.
The hardtop provides additional protection at the helm, while the boat's walkaround layout allows convenient movement between the cockpit, helm and bow.

UPDATED POWER, SYSTEMS & OFFSHORE CAPABILITY
The Grady-White Marlin 300 offers a combination that can be difficult to find in a single platform: serious offshore fishing capability, a large usable cockpit, protected helm, walkaround access and genuine overnight accommodations.
This particular Marlin stands apart because the updates extend well beyond cosmetics. The twin 2021 Suzuki 300 HP four-strokes provide 600 HP of newer power with very low hours, while the approximately one-year-old generator, recent electronics, autopilot, updated electrical equipment and bow thruster address many of the systems that matter most when evaluating an older offshore boat.
Add air conditioning, a complete galley, flat-screen TV, marine head, shore power, hot water, outriggers and a 306-gallon fuel capacity, and this becomes a versatile platform for offshore fishing, coastal cruising, island hopping and extended weekends aboard.
For a buyer looking for a proven Grady-White platform with substantially newer power and meaningful systems updates, this Marlin 300 deserves serious consideration.

Grady-White Marlin 300: BoatTEST Review
Overview
The Grady White Marlin 300 is a classic offshore walkaround boat that blends the features of an express fishing boat with the fishing amenities typically found on center consoles. Unlike many center consoles, it offers overnight accommodations, making it a versatile and family-friendly vessel. Measuring 30 feet 6 inches in length overall with a beam of 10 feet 7 inches, the Marlin 300 provides a spacious and stable platform for offshore fishing and extended trips.
Exterior Design and Cockpit
The Marlin 300 features a hull draft of 23 inches and a closed foredeck with a protected bridge and high windshield, which effectively shed green water in rough seas, ensuring a dry and safe ride offshore. The cockpit is designed with fishing in mind, offering 8 feet 10 inches of space from bolster to bolster and 6 feet 6 inches from the transom to the bait prep station, allowing ample room for multiple anglers to move and fish comfortably. The cockpit is 28 inches deep, with large bolsters and sturdy tow rails enhancing safety. Storage is well thought out, including rod storage under the gunnels and multiple rod holders on the cap rails and hardtop. The transom includes a door leading to a stern platform with a four-step ladder and grab rail for easy water access. Additional features include a freshwater shower wand, shore power connections, engine freshwater flush attachments, washdown hoses, battery switches, and circuit breakers housed in a dedicated compartment. The transom deck incorporates a cutting board over a storage compartment with pull-out tubs and battery storage below. A transom bench seat provides comfortable seating, and hatches grant access to the optional Fisher Panda 5 kW generator, pumps, seacock levers, water tanks, and a large insulated fish box.
Helm and Bridge Features
The helm deck is equipped with optional command chairs that are adjustable both vertically and horizontally, featuring ventilated backrests, swivel seats, flip-up bolsters and armrests, and fold-down footrests. Storage is integrated into the helm seats with locking drawers. The dash offers ample space for electronics and includes a Yamaha engine monitoring screen, compass, accessory switches, and a stainless steel tilt steering wheel. Controls for the twin Yamaha 300 horsepower V6 4.2-liter four-stroke outboards, trim tabs, stereo remote, and optional bow thruster are ergonomically positioned for ease of use. The fiberglass hardtop with a painted aluminum frame includes lockable storage boxes, storage nets, spreader lights, and opening side vents. Strata glass front and side curtains complete the enclosure, making the boat suitable for three-season use. Walk-around side decks with nine-inch bulwarks and tall rails provide safe access to the foredeck, which features a recessed design, a windlass with foot controls, a large hatch for the rode locker, and cushioned seating on the trunk cabin.
Interior Living Spaces
Below deck, the Marlin 300 offers comfortable accommodations suitable for overnight stays. The cabin includes a small galley to port equipped with a sink providing hot and cold running water, an electric stovetop set into a Corian countertop, a microwave, and a refrigerator. The bow features a dinette with a cherry wood table that converts into a V-berth. To starboard, there is an enclosed wet head with standing headroom, and a crawl-in mid-cabin contains a double berth, an opening port light, and rod holders. The interior is finished with a teak and holly sole and includes a six-gallon water heater and a 32-gallon fresh water tank, all standard equipment enhancing comfort and convenience.
Power and Performance
The test boat weighed an estimated 10,615 pounds with three people aboard, 39% fuel, and test power installed. Powered by twin 300 horsepower Yamaha V6 4.2-liter four-stroke outboards, the Marlin 300 achieved a top speed of 50 miles per hour at 5,900 RPM. The best cruise speed was 27.6 miles per hour at 3,500 RPM, delivering fuel efficiency of 1.5 miles per gallon and a range of approximately 390 statute miles with a 10% fuel reserve from its 282-gallon capacity. Acceleration was brisk, reaching planing speed in 3.3 seconds, 20 miles per hour in 3.9 seconds, and 30 miles per hour in 6.9 seconds. The hull’s 19.5-degree dead rise at the transom provided smooth handling through one-foot chop and 10-mile-per-hour gusting winds. Maneuverability was responsive and predictable, aided by the optional bow thruster and twin outboards, which facilitated easy docking and slip entry.
Conclusion
The Grady White Marlin 300 has been a mainstay in the brand’s lineup since 1989 for good reason. It offers a dry, secure, and comfortable platform suitable for families and anglers alike, combining offshore fishing capabilities with overnight accommodations. Its spacious cockpit, well-thought-out fishing amenities, protective design, and reliable performance make it a versatile vessel that meets the needs of a wide range of boaters. Overall, the Marlin 300 stands out as a well-rounded offshore walkaround that balances fishing functionality with cruising comfort.
