You have a lot of stuff going on there pards. Way more than what can be sorted out over words on the internet.

The proper setup for what you're running is a worked 24 Raker, 2nd hole up. Should be 65 mph at 5,600 rpms. You can't run mounted flat on transom any higher, it'll be prop slip crazy.

I am knowledge free on Johnrudes, but Fred (Championman) might can help you sort out your motor issues.

We will always recommend a known good setup and see what it does from there, I don't think you're anywhere near that now.
