Hi Brad, just what do you want to know? Those 30 horse Johnsons will push your boat pretty good. You will need a good size boat. I run my tens in tandem, and it sure is fun! I know nothing about counter rotating propellers. I stacked two control boxes together and that works. I use a cable system for steering. That does take some engineering. I don’t know how handy you are and how much time you want to spend setting it up. It is a good off season project for sure. I have lots of pictures, if you are a member PM me and I will send some to you.
