GLOSSARY OF TERMS
AERATION - The mixing of air (bubbles) with the water
under the boat. This helps to lift the boat from the water to
increase your speed. You do not want aerated water in the pitot
tube as it will cause the speedo to read low. There should be
solid (non-aerated) water running through the pitot tube.
CALIBRATION - The process of matching an instrument’s
reading to a piece of test equipment with accurate data to
ensure the gauge is reading properly. Speedometers cannot be
calibrated in the field.
KICK-UP - A type of pitot tube that will swing out of the
way if it hits debris in the water. Also good to clear a
trailer bunk or when beaching a boat.
PITOT (pee-toe) MOUNT - A part attached to the transom to
pickup water (psi) as the boat travels through the water. This
water runs through a hose to the mechanical speedo in the dash
to register your speed.
TATTLE TALE - A device used to recall the highest speed
traveled. On a GPS speedo this is done with the flick of a
switch. On a standard speedo, the gauge will have a second
pointer.

F.Y.I.
In order to produce accurate speedo readings, the pitot
tube must be placed in unaerated water.
New stepped bottom technology can make
it tricky to get the pitot tube mounted correctly.
A thru-hull fitting allows the tube to
be mounted on the step bottoms and the hose routed directly through
the hull to the speedo, leaving no hose exposed. |
