____________________________________________________________________________________
The Suzuki DF60ATL is a technologically
sophisticated outboard that distinguishes itself in the 60 Hp class
through its use of a Dual Overhead Camshaft (DOHC) powerhead with four
valves per cylinder. Its engineering focus is clearly on mechanical
efficiency and fuel economy, highlighted by the integration of Suzuki's
Lean Burn Control System, which optimizes the air-fuel mixture for
significant fuel savings across a broad operating range.
The inclusion of a maintenance-free, self-adjusting timing chain - a
first in its class - enhances durability and reduces long-term upkeep.
Users benefit from the Easy Start System for effortless ignition and a
robust 19-amp alternator that provides ample power for electronics even
at low engine speeds. The DF60ATL is engineered for durability,
incorporating a multi-layer anti-corrosion finish to withstand harsh
marine environments, making it a reliable and clean-operating powerplant
for a wide range of boat types.

The Suzuki DF60ATL is a versatile outboard suited for a wide range of
small to mid-sized boats requiring remote steering and a 20-inch
transom. Its power and compact design make it an excellent choice for
aluminum fishing boats, jon boats, and bay boats where shallow water
maneuvering is required. It is also a popular powerplant for pontoons
and small deck boats, providing ample thrust for family cruising and
water sports.
Additionally, its weight and dimensions are well-matched for rigid
inflatable boats (RIBs) approximately 4.5 to 5.5 meters in length and
small center console skiffs, where efficiency and reliability are
paramount. The DF60ATL is the standard configuration for operators who
prefer a console or helm, integrating seamlessly with modern boat
designs for a wide range of recreational and commercial activities.
