|my rpm gauge seems to work great til around 3000 rpms, then it flips out after that. Once I pass 3000, it goes down to like 2000 and kind of bounces around. Any advice as to whats wrong or how to fix it?|
|how old is your boat? ie points or electronic? |
are all the wires tight?
my old teleflex did the same thing, so i replaced it.

|since you have efi/electronic ignition, it is probably the gauge if the wires look good. pull the gauge and wiggle the wires and see if it fluctuates. if you have a dwell meter with the high rpm scale, you could check the signal at the dash. your ground and power wires for the tach need to be good also. |
gauges pop up all the time on ebay, but buying used is always iffy. if it's bad, replace it soon if you like to run at the redline.
|Tnaks again Thomas! I'll check it out some more tomorrow.|
