Review on Sierra 58255P Tach 7K Amega by Black Holstead

Revainrating 5 out of 5

The touch works now, looks good, fits in with the rest, the hardware is there.

The last tachometer was dead and then just went up to 4000rpm and dropped off as the engine revved up, this one works great. 1995 Mercruiser 7.4, uses 4p (4 pulse) 8c (8 cylinder) tuning for a four-stroke V-8 engine. The tachometer is powered by the gray wire that comes from the negative side of the coil to the transmit connector on the back of the gauge.

Pros
  • Black dial, red graduations, white numerals, bright white pointer
Cons
  • Operating RPM
