I need to get a tach. It felt like it never completely wound up.
It ran really smooth, but it sounded like it still had more it could go.
Not that it felt struggling at all, just that it still had more to give.

Well few of us have Oscilloscope ears, and that is why a tach is the most important gauge you can ever have on a boat

The 7000 Faria Tach should be here Monday.
I checked the current prop on the Johnson. It has a 13.25x17.
My Suzuki has a 13.5x15.
It has the same splines.
I'll see where both props put me for RPMs at WOT and post back.
