Thanks for all of the earlier posts as I purchased my 87 Mariner this spring. The boat has been everything I had hoped for with my family spending the last week on the boat touring around the islands in Lake Erie.
I have noticed that the tachometers on the boat seem rather inconsistent. The often read in the 45-60,000 range when we are cruising probably around 25-30,000 range. Then other times they read what I perceve to be accurate. Does anyone have any experience with this. Should I be looking at wiring or do the gauges wear out and need to be replaced. Any help is appreciated.
It is possible you have a bad connection, however it is common for the Tachs to eventually fail. Normal cruise is in the 3,000 RPM range, with a max of 4,500 RPM or so.
Hope this helps!
