The Innovation
The DF40A Ari outboard on this Marshall m4 offers 42% more forward thrust and is 12% more efficient. This outboard uses a timing chain instead of a rubber belt.
The DF40A vs DF40A ARI
Compared to the classic DF40A, the DF40A ARI delivers 42% more forward thrust, improving outboard acceleration efficiency by 12%.
The thermal unit of this Suzuki 4-stroke outboard comes from the DF60AV and takes up 943 cc on its cubature, with three cylinders in a row, which makes it lighter and more compact.
