What was your temperature concern? At the same hp input, a bravo drive would actually prefer a higher rpm vs lower.

Diego, hope you were aware of this...

The builder's expectation of a 4000 RPM WOT limit is totally unrealistic. In my 40 years of boating with gasoline powered I/O watercraft I have never been on or operated a vessel that had a 4000 RPM limit. Having said that...I could understand a 5600 RPM limit but 4000 RPM....really?

I'm guessing that was a typo?? Maybe 5000 RPM?
