I noticed on Mercury's website, they have a prop slip calculater. How do you adjust calcs for twin drives, or two props?
Or do you?
Thanks guys,

About the only thing you may have to do different is take an average rpm if the engines are running slightly different. Otherwise, calculate just the same as a single.

As far as my tachs read, they are running the same.
Thank you,
