This 25 hp has less than 2 hours on it and already broken. Well anyway. I put the boat in storage for one month and go to fire it up today and no start. Fuel pump works, good fuel(non ethonal), I'm getting fuel. Spark plugs good, but I'm not getting spark off of any of the 3 spark plug wires.

On a side note every single time I buy a mercury they have broken with minimal hours on them from things just like this, storage for a month. Should have just kept the 1977 evinrude 35 that had god knows how many hours on it.

Just grabbed my volt meter and I have no voltage going to the coil packs koeo and koes. Checked fuse and it's good.

Some times motors are put in storage and for some reason, the red tether cord is removed. Check that the kill switch is in the run position.

Trade it in on your old Evinrude 35, you will be a lot happier!

Checked red tether cord that's fine. I have 2 of these motors and this one has been problematic since day one. This one has had a new lower unit, 2 water pumps, and now it's broken again. I'll just take it back to the dealer for more warranty repair.
