This is the exact GPS speedometer that we at Silver Cove Marine use in all of our dash refurbishments, and it will eliminate your pitot-style speedometer(s).  This speedometer will fit all Nautique dashboards from 1990 - 2002.
 
IMPORTANT - The wiring harness in the dash will require some work in order to be compatible with this gauge.  Specifically, the connections may need to be converted to ring terminals.  If you are not comfortable making these modifications, please use our Dash Restoration Service (under the Service link on our website).
