Sea World Ship MGG talks to you about the news in the field of sustainable engines from two well-known companies.
Suzuki
Suzuki has announced its global growth plan until 2030, based on the one hand on the development of new models and on the other on environmental sustainability. The plan is very complex and obviously involves cars, motorbikes and outboard engines and all production plants.
For outboards, the Japanese company plans to launch - by 2024 - a range of electric motors. At the moment it is not known what power order these units will be in, but it is very probable that the range will range between 1 and 10 kW.
Suzuki has also announced that it will launch five new outboard engines by 2030 (among which there will certainly be the long-awaited top-of-the-range model with a power of 400 or 450 hp). For more powerful outboard engines, Suzuki is evaluating the possibility of adopting zero-carbon dioxide emission fuels.
Mercury
Mercury Marine is also once again entering the field on the very hot front of electric propulsion systems for boats, with the aim of giving a strong boost to their diffusion and consequently implementing a market that today we can still consider to be in its infancy.
After Avator 7.5e, launched at the Consumer Electronics Show (CES) last January, the Brunswick Corporation motoring division presented the Avator 20e and 35e outboards at the recent Genoa Boat Show, models already on sale, followed by the presentation of two more outboards to reach a total of five models in the range by 2024.
Both Mercury models, Avator 20e and Avator 35e, bring with them numerous innovations already observed in the previous Avator 7.5e model. Among these, the use of the pioneering, at least in the nautical sector, the technology of the transversal flux electric motor stands out - so called because the flow of the magnetic field develops in the axial direction between rotors and stators, parallel to the axis of rotation, rather than perpendicular as happens in radial flow electric motors - a solution that makes them more compact, lighter, efficient and capable of developing higher torque values than traditional electric motors.
The 20e and 35e acronyms of the new Avators identify the power delivered by their respective 2 kW and 3.5 kW engines, which according to the manufacturer guarantee acceleration comparable to Mercury internal combustion engines of 5HP and 9.9HP respectively.
Mastervolt, of the Navico group (which is part of Brunskick together with Mercury) has specially designed the lithium ion battery that powers the Avator 20e and 35e, a 2300 Wh accumulator developed exclusively for marine applications. It is drop-proof and IP67 waterproof class.
Boaters can choose to connect directly to a 2300Wh battery for maximum simplicity and portability, or extend the range and autonomy of their electric outboards by adding an Avator Power Center, which offers the ability to place up to four batteries in series . The Power Center serves as a central hub for power cable connections, allowing for simple battery pack installation. Connections of the power cable to the battery are quick and easy thanks to the twist-lock connector that requires no tools for assembly.
