Dyno graphs for mercury 4 strokes

[ar300johnson]

I have seen the dyno power graphs for mercury 300x, 300xs, and 250xs but have not seen any for the new 300r, 300proxs, and the 400r. I’ m just curious about the new motors and the 400r.

I have been looking for the same thing for the 350/400r verado. I just talked to USP marine performance who has been in the auto tuning game a long time and are just now breaking into marine, they said they have a dyno on the way so hopefully they will be able to get some real numbers for everyone.
