Nice to see the first test on it - why the hell they had to go for such a huge displacement and so much weight is beyond me.

A Mercury 300xs has a 3.3L block - these things are 5.3L - no wonder they weigh so much!!!

Probably so they can use it as the basis for a future even larger HP engine

Evinrude can make the existing E-Tec 250HP produce 350 HP I was told by one of the head technicians of BRP in Belgium. Only problem if they do that is pollution. They do not longer comply with the environmental requirements.

So imagine, getting 350 HP out of a 240 kg engine …
