Question: does the set include the new sending units for the gauges, or do you reuse the original on the boat
Document: I replaced the original gauges in my 1989 Wellcraft 220XL Elite with these & they are a nice set. The speedo actually reads slower than GPS which is rare for a pitot type. Most boat speedos are very "friendly". I had them several months now with no complaints. Got these from a Amazon Marketplace affiliate with no problems.
Bought these for my 1999 Wellcraft with a Mercruiser I/O. Gauges were fairly easy to install. They work just fine. Backlighting appears to be better than original gauges. One note of caution; when installing the RPM gauge, make sure to note the wiring color connections to the terminal labels. I found that the terminals were reversed for the side on which they were located on the back of the gauge as compared with the original.
Nice replacement for my old gauges.
If you're looking for some really nice gauges at a great price then look no further as you have found them.
The gauges are exactly as pictured and have provided a very clean looking helm station. The were quite easy to install and I have no major complaints.
Answer: no
