 | Most likely just the seal. Happened to me last year, same thing, replaced the seal and i was back in business. Glad i found it since i change my fluid before winter storage. Hate to have it freeze. |

 | It is a bad seal I had it happen too. I removed the plug and water just came pouring out, after the water came out I had milky grease come out next. |

 | I would have your lower unit pressure tested ASAP.  Either have a dealer remove the LU or you can do it yourself.  I can't speak for Evinrudes/Yamaha's/Johnson's/Suzukis/Hondas but I've done it on Merc's and it's pretty easy. 
 Changing the seals themselves in my opinion is best left to the dealer.  I know that Merc's require special tools.
