New design Rotax outboard motor shaking the boating world
During a dealer conference of BRP in August 2022 they introduced to their audience a new and totally outside of the box thinking design of an outboard motor. The new design was shown in 3 new boats from the BRP portfolio of boating companies Manitou pontoons, Alumacraft and Quintrex boats.
In 2020 BRP announced that they would step out of the outboard motor business by abandoning the Evinrude brand they had taken over before when OMC was dissolved. The 52-year-old ownership of Rotax by BRP (1970 – 2022) has resulted in a totally new outboard engine design which we will explain in detail below the cut-away photo.
BRP-Rotax outboard engine
The BRP - Rotax new outboard motor completely redesigned, reimagined and rethought for its Manitou pontoons (20 – 26 foot), AlumaCraft and Quintrix boats with a 115hp and a 150hp versions in what they call Stealth Technology. They deliver the same advantages as the traditional outboard engines – such as price, performance, handling, ease of maintenance, and full trim plus, additional benefits: it’s hidden, it’s quiet and it’s efficient.
A 1.9 litre three-cylinder two stroke power head is shared by 115 hp and 150 hp
versions of the Rotax outboard, with the 150 hp gaining RAVE variable exhaust
ports. Both motors use the OMC E-Tec direct fuel injection system and are equipped
with power hydraulic steering.
The outboard motor cover is water-tight and secured with 15 bolts. Air enters the
engine through a tube routed into the boat transom. Injector oil is carried in a 15.9
litter (3.5-gallon) reservoir within the boat. Rotax says the motor weighs just under
227Kg (500 pounds). It mounts on a standard outboard transom and bolt holes and
has a 64 cm (25-inch) length. Rotax says the design is scalable to make more
power.
Partially submerged underwater, hidden under the boat, the engine is smooth and
quiet at any speed. It doesn’t block the view at the stern and frees up valuable space
on the boat. The New BRP/Rotax Stealth Technology outboard is efficient when
judging on the provided data in comparison with present traditional outboard
engines: 20% improved fuel efficiency – 12% reduction in reportable emissions with
a 98% reduction in CO2 at idle compared with other leading outboard engine brands.
The three boats from Manitou pontoon and the AlumaCraft and Quintrex boats have
been crafted for an optimal integration of the new Stealth Technology Rotax
outboard engine. Conveniently priced within their segments these new models for
the 2023 line-up will attract many new customers for a new boating experience.
