    Ya'll no longer have a choice.
    They're only offering a single recreational model for outboards
    and one for commercial usage.

    Hey guys I bought one last fall for my 02 merc 20hp. Customer service was great and easy to order from them over the phone. easy to follow directions and are also easy to install about twenty minutes for a basic velcro transom install. and they work beautifully.

    So EASY a caveman could do it ;D

    Got my Tach today!!! I have a quick install question that hopefully someone can answer. Is the 03 25hp stroke mercury 180° = 2 sparks per revolution?

    update your adobe reader   ;)

    2 stroke outboards require 1 spark per cylinder on each revolution
    and because you wrap the sensor wire around a single plug wire
    I'm going to say 1 spark per revolution is the setting you need.

    Good theory, and according to Tiny Tach you are correct because only one wire is wrapped!

    Thanks for finding that chart!!

    :mad: After routing the wire all the way to the motor, I came up a foot short! NowI gotta pay an extra ten bux to have them add length. And its not as simple as adding wire, you gotta add coiling(if thats an actual word)! :(

    ok so i got it on the 360* setting, fired it up and everything seems to be working great including the smoke alarm in my house :eek: guess i should have taken it outside first :D ;D :cool:

    disregard my last transmission scotty ;) when i changed it back to the 360* setting i cranked it and it seemed to read just fine until i remembered that i had forgotten to plug the frackin' spark plug wire back on :mad: now its reading funny again :(

    Did you try a fourth wrap on the wire? Instructions said something about adding wraps for stronger signal.

    yep tried that already, whats weird is that the top spark plug wire was disconnected and she seemed like she was working right, motor ran too  :-? thought i had it all buttoned up so i went back in to pour another glass of  sweet tea in celebration of another successful install on the boat, i walk back out and see the wires disconnected   [smiley=1-smack-myself.gif] now i'm back to square one  [smiley=cloud.gif]
