1994 Marlin 350 SF
Twin 2024 Yamaha 300s – Highly Customized Offshore Fishing Machine
This 1994 Marlin 350 SF has been completely transformed into the most custom, fully upgraded fishing platform ever built on this hull. Featuring a 2024 twin Yamaha 300 HP outboard repower, extensive structural and systems upgrades, and a purpose-built fishing layout, this vessel combines legendary Marlin ride quality with modern outboard performance and technology.
The twin 2024 Yamaha 300s deliver 600 total horsepower with outstanding reliability, fuel efficiency, and reduced maintenance. The custom outboard conversion opens up the cockpit and simplifies mechanical access while dramatically improving performance and serviceability.
A custom hard top and full tuna tower provide superior visibility, shade, and offshore capability, making this boat equally at home spotting fish offshore or running long canyon missions. Fresh bottom paint ensures she’s ready to launch and fish immediately.
The cockpit has been engineered into a tournament-ready workspace, optimized for crew movement and serious offshore action. Inside, the cabin offers classic sportfish comfort with functional accommodations for overnight trips and extended offshore runs.
At the helm, you’ll find a fully modernized electronics suite featuring Furuno touchscreen navigation and radar, integrated autopilot, and clean system integration for confident operation from harbor to deep water. Entertainment and electrical systems have been upgraded with a Fusion premium sound system, Magnum inverter, and Victron amp meter for reliable power management at sea.
This is not a cosmetic refit — this is a full performance and systems evolution of an iconic sportfish hull.
