Strange thing, the kit came with hose but no clamps. Do they expect one to just use a friction fit to hold? For today, since I didn't have any clamps that small, a bit of rigging wire used like a bread twist tie did the trick.

Did two runs up the rpm at the dock. One in neutral and one in gear just to see the differences.

Neutral:
RPM in. Hg
700 13-15
1000 16.5
1500 19
2000 19

GEAR:
RPM in. Hg
700 13-15
1000 13-15
1500 4

Sunday when out for a sail I'll chart some more numbers and see what shows. Then I can learn what it all means!
