Vacuum Gauge

[GregH]

After driving all over town to get the fittings for the manifold tee and hose barbs, managed to get the vacuum gauge installed. Using the supplied plastic hose for now, in the spring I'll change over to copper.

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!
