The new smartcraft monitor do you still have the link for the gauge. and would you replace the speedo or the RPM gauge. My speedo stays clogged up all the time but the rpm might be a little more close to the rpms. Do you have to have a computer or is this plug and play. What kind of problems have these monitors had. Also does Mercury sell a wrench for the water seperator filter. 2007 250 Pro XS.
