TECHNOLOGY REPORT
The Avator series also features swappable
lithium-ion batteries. The
48V/1kWh pack was developed in partnership
with Mastervolt and is IP67
rated for water resistance.
All Avator outboards will feature a
transverse-flux motor, which was chosen
" because of its high torque density, "
according to Andrew Przybyl, engine
and vessel calibration technical specialist
at Mercury Marine. " The motor can
generate instant torque at low rpm, "
Przybyl explained. " Because of that, we
were able to design a large-diameter
three-blade prop that spins slower,
which is better for efficiency and overall
performance. The result is faster 0-to4-mph
acceleration and higher efficiency
than similar competitive outboards. "
Power status and estimated runtime
of the Avator is tracked via a digital
display mounted on the unit. A 110W
charger is standard. Mercury did not
provide an official charging time for the
7.5e but did state that faster charging
speeds are an option. Mercury states
that at 100% constant throttle, the
range of the 7.5e is five miles (8 km) or
60 minutes when powering a 13-ft.
(13.9-m), 382-lb (173-kg) boat. At 25%
constant throttle, the range increases to
34 miles (55 km) or 19 hours.
The total weight of the 7.5e excluding
the battery is 43 lb. (19.5 kg). The batThe

outboards.
tery itself weighs 17 lb. (7.6 kg). With the
battery installed, the 7.5e weighs approximately
19 lb. (8.6 kg) more than an
equivalent-output ICE outboard.
AT CES 2023, Brunswick Corporation
also announced the launch of Veer, the
company's new entry-level boat brand
designed to support electric propulsion.
" Our target consumer is looking for a
brand that brings new energy and new
thinking to the outdoor experience, "
said Matt Atilano, Veer director of strategy.
" Through Veer, we look forward to
delivering on these desires and on
Brunswick's promise to expand access
to the water and democratize boating. "
Veer's first offering will be the X13, a
13-ft. (four meter) hull with a rotomolded
polyethylene construction. The X13
was designed to accommodate the
Avator electric outboards but also can
be fitted with Mercury's gasoline
FourStroke units. The X13 features a
shallow draft of just 6.3 in. (16 cm) and
weighs in at 382 lb. (173 kg). Pricing for
the X13 starts at $11,995 USD and will be
available in spring 2023.
