Hi Gery,

I might be wrong and don't buy it on my word but I would think probably.

Have a look at this link from faria and see if you can find your outboard and pole settings on the list

http://faria-instruments.com/site_manuals/IS0086t.pdf

If so and the other one can be set to the same number of poles it should work

I think all tachometers work on the same principle and the number if poles is just the number of pulses that comes down the signal wire.

Console end you will need a switched positive, Earth and signal wire. On my loom that yellow, black and green.

On another note be wary of the quality of some gauges, it's a harsh environment for a gauge on a rib! I got a new faria one on eBay for £35 after 6 months of hard looking

Just looked at picture 1 a bit closer.

Your outboard will need to have either 5, 6 or 10 pulses for this gauge to work.

A lot of gauges will show the revs when engine was turned off. Should reset to zero when they are next powered up.
