Hello Mr. Almetelo.

It is an F425. Direct fuel injected. 5 fuel pumps. Why not 8? I don't think I would have been bragging about 5 pumps. Some things are better left unsaid.

should have made it with enclosed cooling and add another 35 lbs,

To heavy!!! With more 50kg you have a 627hp from seven marine
Fortunately in not the problemtic block from the F350

I was expecting more... a supercharged or turbo motor.. Maybe in the future

Let way and see the results

Thanks for the news Boscoe

For some boats I suspect it will be the perfect companion. Yamaha does not develop motors in a vacuum. They coordinate and collaborate quite extensively with their boat builder partners. Probably would not have been developed if boat builders were not expressing a need for it.

Boats come first, then the motors. Same with air planes.

The weight of the motor up against a 40' ~ 50' boat is a non-issue.
