Command link lcd speed WAY off

[engdept1]

Command link is showing a speed of 63mph with the boat sitting on the trailer in the yard. Engines are f300s if that makes any difference. What should I try to get this thing to act right?

[fairdeal]

I'm guessing you have a sensor which converts pitot tube water pressure to Command Link speed - and there is either a blockage in the pitot tube - or in the sensor - which is causing the bad reading.

but perhaps not

does your Command Link gauge tell you the time?

[engdept1]

I haven't noticed if it tells the time or not. I'll check tomorrow.

[fairdeal]

reason I ask - if you had time, it would mean it was connected to a GPS -
which should be giving you your speed - not a pitot tube

No time so I guess its the tube. I'm not gonna bother with it. Now I just need to figure out how to connect to my nss evo 2.
