2019 Yamaha 90 HP VF90XA V MAX SHO Outboard Motor

This VF90XA runs Yamaha's V MAX SHO performance tune of the 1832cc, 90 hp inline-four, mounted on a 25-inch shaft; it is a remote-steer, electric-start build with a dry weight of 362 lbs listed.

What a taller transom gets you

Choosing a longer shaft over a shorter one comes down entirely to how tall your transom sits; horsepower and tune stay identical regardless of shaft length on this platform. Because this is the SHO build, it shares its block with the rest of Yamaha's 90 hp line but runs a more aggressive tune aimed at buyers chasing performance from the same displacement rather than extra cubic inches.

Steering here runs through a helm-mounted wheel and cables, not a tiller handle, so confirm your boat already carries that hardware. At 362 lbs, check your transom rating and any hoist or trailer-mounted lift against that figure too.

As with any performance-tuned engine, fuel quality and filter upkeep matter more here than on a standard-output 90, since tighter tolerances leave less margin for stale fuel or moisture picked up in a half-empty tank over a long winter layup.

Questions buyers ask

Is this a jet or propeller motor? A conventional propeller-driven outboard, not a jet drive.

What's the warranty? Yamaha covers it with a 3-year warranty.
