THEY NEVER CEASE TO AMAZE
This line of trusty Mercury FourStrokes offers
advanced features that keep the good times going.
❖ Exclusive dual-water gearcase intakes provide
a constant supply of cooling water to decrease
exhaust temperature and protect gearcase seals.
❖ Manual recoil starting comes standard. So even
if your battery quits, you can start up and get
home safely.
ACTION-PACKED
We put the “fun” in functionality with these
feature-rich outboards.
❖ 15-amp, 186-watt alternator delivers
on-demand battery charging and power for
electronics and lights.
❖ Available power trim and tilt make it easy
to optimize the performance of your boat.
❖ Automatic decompression reduces cylinder
pressure, so pull-starting the engine isn’t
a pain.
❖ For ultimate shallow-water maneuverability,
Mercury offers a 25 hp Jet model.
A quiet companion.
Honda 25 hp is up to 58% louder
at idle than Mercury 25 hp FourStroke.
❖ Integrated idle-relief silencer reduces engine noise
at low speeds.
❖ Through-prop exhaust delivers quieter operation.
❖ Tuned cowl induction helps achieve best-in-class
noise reduction.
