They are accurate within 1 mph to my GPS on the last 3 boats I owned.....

The problem is after my speedo gets to 82 it wont read any higher.... My GPS keeps climbing but water starts comming out from the back of the speedo.... Is there a pressure relief valve in there? Does the speedo hose need to be zip tied again? I cant look under the dash at 80+ nor can I find someone else to...

I would like the speedo to stop leaking and read full speed...
