Source: Mercury Marine Engineering Dept. – October 2005. Test conducted on a 17' aluminum bass boat using a Mercury 50 hp EFI
FourStroke and a Mercury 50 hp two-stroke. Assumptions: Engines are run at 100 hours per year over five years. Price of gas is
US $4.00 per gallon/ US $1.06 per liter.

Big-time power.
With a longer design and bigger components,
Mercury BigFoot was made specifically to
deliver the type of
power, thrust and control
that wider, heavier boats demand.
❖
20% larger prop
increases control especially at low speeds.
❖
Taller gearcase
puts the prop deeper, below turbulent water,
for improved performance.
❖
A
low 2.33:1 gear ratio
delivers thrust and maneuverability that
big loads demand.
❖
Oversized Antiventilation Plate
Oversized design prevents air from being drawn
into the prop, which increases efficiency.
Mercury 50 hp EFI FourStroke vs. a Conventional 50 hp Two-Stroke
❖
At cruise, EFI FourStroke is
39% more fuel-efficient
.
❖
FourStroke offers
63 more miles
(101 km) of range per 21-gallon
(80-liter) tank
.
❖
Over five years, 50 hp FourStrokes
could
save you nearly US
$
1,300
on fuel and oil alone.
❖
FourStrokes
cost less to maintain
thanks to the proven EFI system,
longer spark life and none of the
gumming, decarbonization or ring-
and-cylinder issues of carbureted
two-strokes.
❖
60 – 40 hp FourStrokes tout
an
environmentally friendly
CARB three-star ultra-low
emissions rating.
❖
EFI improves fuel flow
control and overall efficiency.
❖
Exceptional fuel economy
decreases the impact on the
environment.
❖
Experience
better fuel efficiency,
reduced emissions and a
smoother ride,
without sacrificing
power or performance.
❖
At top speed, Mercury 50 hp
FourStroke
was nearly 1.5 mph
(1.9 kmh) faster
and within
2.8 seconds of its sister two-stroke
from 0 – 20 mph (0 – 32 kmh).
❖
Through-prop exhaust is smoke-
free and up to
30% quieter
than
a conventional two-stroke.
