Repowering Your Cabo 35: From Cummins 6BTA 5.9 to the FPT NEF-400 5.9
Why Cabo 35 owners are choosing to repower now
The Cabo 35 Express and Flybridge are among the most respected sportfishing boats ever built—fast, capable, and beautifully balanced.
But many are still running original Cummins 6BTA 5.9 engines from the late 1990s or early 2000s. While reliable, age and older fuel systems
mean rising maintenance costs and limited performance compared to today’s technology.
Repowering with the Fiat Powertrain (FPT) NEF-400 5.9 offers the next level of performance: smoother operation, cleaner emissions, and lower fuel burn—
all while maintaining the rugged dependability Cabo owners expect.
Modern technology meets proven reliability
The FPT NEF-400 5.9 brings advanced common-rail fuel injection, improved combustion efficiency, and refined noise control.
It’s a direct evolution of the dependable inline-six platform, but built with today’s materials, sensors, and diagnostics.
