What's this motor

[McGillicuddy]

Yes Optimax. Great motors although early on they had some problems in some HPs.

Direct injection was the revolution that saved the 2 stroke. Numerous technologies available to directily inject the required amount of fuel/oil to cylinders for maximum burn and efficiency. Very efficient and environmentally friendly.

OMC had the problematic FICHT collaboration, leading Evinrude/BRP to rework the FICHT into the Etec; Merc's Optimax, Tohatsu's TLDI and Yammie's HPDI are all variants of the tech. They all do the fuel injection it a little differently.
