Vision Marine enters agreement with Weismann Marine

Under the agreement, Weismann Marine will design, develop, procure materials, and produce lower unit prototypes for testing and evaluation.
MONTREAL — Vision Marine Technologies Inc. has a joined a development agreement with Weismann Marine LLC to design and develop a lower unit assembly for the Vision Marine’s E-Motion™ 180 HP outboard propulsion system.
Vision Marine says the torque output developed by the E-Motion™ 180hp electric powertrain requires a lower unit capable of cooling the motor while staying noiseless. They expect collaboration with Weismann Marine should enable them to provide this type of technology to OEMs and consumers of the marine industry.
“The lower unit converts the power of the outboard motor, which transfers power from the engine to the prop shaft, which moves the propeller, which in turns propels the boat. The ultimate goal is to create the most efficient power transfer to the propellor. The performance lower unit can be run much higher than a traditional gearcase. This is an important piece of the puzzle,” said Alexandre Mongeon, co-founder and CEO of Vision Marine in a statement.
Weismann Marine’s and Vision Marine’s shared objective is to design an operational prototype for a lower unit designated “MK5”. The MK5 will reduce power loss through the gear system, reduce hydrodynamic drag and mitigate operational gear noise.
They expect the prototype will maximize battery life through propeller efficiency, provide adequate cooling to the powerhead, and have a small nacelle. Under the agreement, Weismann Marine will design, develop, procure materials, and produce lower unit prototypes for testing and evaluation.
Once completed, Vision Marine will incorporate the lower unit into the E-Motion™ powertrain through their Manufacture & Supply Agreement with Linamar Corporation, a subsidiary of McLaren Engineering.
