Works perfectly, wiring colors match, connectors work with OEM coil
I installed this on my 87 merc 2 stroke 25hp motor. This was an exact match for the old CDI box AND the exact same as the cdi box on my 9.9hp 2 stroke which is also mid 80s. I knew this motor was getting a no spark condition and replacing the cdi box resulted in beautiful blue spark.The wire colors all matched my motor except for the two wires going to the ignition coils but that was not an issue since if they are backwards the motor will not run and you can simply swap them to correct it.The wiring connectors and rubber insulation over the connectors worked perfectly with the stock stator wires which seems to be something that other Chinese made cdi boxes get wrong.One question I have for the manufacturer is do these boxes have a rev limiter built in and if so what is it?

Cheap and good powerpack
This powerpack works perfect on my 1996 Mercury 8 hp. It looks very aftermarket (because it is blue), but it is cheap and it works and that is the most important!

I am assuming the wrong item was sent.
I bought this for a 25 hp Mercury outboard. I was obviously sent the wrong item, the color was wrong, also the wiring harness came out on the wrong side. This interfered with my exhaust manifold cover and what are they eventually burn the wires. Return this item and requested a refund.

En las pruebas, muy bien.
Me ha funcionado bien, ha desaparecio el fallo que tenia en un bobina. Solo he probado un rato en tierra, espero no falle en el mar.
