Does anyone know if this Tach will work with my boat

[BillaVista]

This is the tach:

Amega | SeaStar Solutions


Teleflex Amega 7000 rpm Gas Tachometer

The boat is a 1979 Starcraft Holiday V5 14' Aluminum Runabout with 1979 Johnson SeaHorse Magflash CD 55HP.

Thanks

I don't see why it wouldn't, the pdf says O/B with alt.

I always feel better when I see the back of tachs to make sure they're really universal (lug terminals) and you don't need some special cable/adapter to fit the back of the tach.

there is an accessory (IH14767), the 3-wire harness. Your motor controller may already have a tach plug...which would be sweet...plug-n-play. Otherwise, you need to go into the remote control, find the sender and wire-it in (along with a ground and +12V-Accessory).

That's some neat wiring work BlueFin!

Here's the back of the tach:

Apparently you set the switch to half the number of poles on the alternator. I believe mine has 10, so I will set it to 5.

Will report results (but it will take a while).

Got it installed.

Wired up fine. Correct setting was 6P

Looks good up there Bill! The red accents pop-off nicely!

I don't wish to hijack the thread, but will an automotive tach work on an ob motor? They are both 12v systems and I'm thinking I should be able to route the pulse wire to the tach pole on the electrical block and the + to a hot and - to ground.

firedawg----yeah, you should probably start a separate thread. one issue will be whether you're talking an OB with magneto ignition or one with conventional distributor + coil ignition like a Chrysler.....should work fine on the latter, not sure on former. prolly worth just trying if you or a friend have a spare tach; doubt it would fry the tach if you were wrong.

It depends on the motor. I would think in most cases, probably not. Automotive tachs usually have a switch on the back fro 4 - 6 - 8 cylinder operation, and are generally a different ignition system from an OB. Now, if you happen to have a 4 cylinder, 4-stroke OB with automotive-type ignition, then yes it would work. Otherwise, probably not.
