    genec, the chart speed is global, if you have it set to 5 it is the same for SI, DI. From my experience I know the higher the chart speed is above boat speed makes things look longer. You might try testing at a chart speed closer to boat speed. Maybe Greg (HB) will comment on this.

    Nice report Genec, hope you get your big motor lined out. Rdjj is correct on the global chart speed, I think!

    That changes the equation a lot genec. My brain did not catch that in the first post. Would be interested to see more testing.
