Suzuki 150Hp DF150TX 4 stroke 25″ Extra Long Shaft

Suzuki's DF150TX sends 150 HP through an in-line four-cylinder, DOHC engine on an extra-long shaft stretching to 25 inches, built for boats with a deep transom that need serious offshore power. This unit is sold new.

Shaft length and steering

Twenty-five inches suits larger offshore and bay hulls rather than smaller boats, so confirm your transom height before ordering; remote steering is used here rather than a tiller. Four cylinders with four valves apiece displace 174.9 cubic inches, driven by a self-adjusting, oil-bathed cam chain and geared at 2.50 to 1, weighing in at 485 pounds.

Equipment and rating

Electronic fuel injection pairs with electric start and power trim and tilt, while wet-sump lubrication holds 8 quarts of oil and solid-state ignition runs off a 44-amp alternator. A 3-star, ultra-low emissions rating applies, and both standard and counter rotation are offered, with optional propeller pitches ranging from 17 to 27.

Common questions

Is counter rotation available on this motor? Yes, alongside the standard-rotation setup.

Does it ship with a propeller installed? Propeller selection is optional, with pitches from 17 to 27 sourced separately.

This motor is intended for boats already set up to handle serious offshore power, where the extra shaft length and four-cylinder displacement earn their keep on longer runs. Confirm your existing rigging and helm setup with us before ordering if you're replacing an older engine of a different brand.
