Scoutnut: Actually ASM's can be on (E)BOR's just like they are also allowed to be serving as committee members. According to the policy the Scout's Scoutmaster and any and all relatives are not allowed to serve on the EBOR. The Scoutmaster can attend the (E)BOR but only as an information source for the Board meaning the board can ask him/her questions about the scout. So a Scoutmaster that is unrelated to the Scout and is from another troop can also serve on the EBOR and any other BOR.
For the OP:
Well you always have the Scout Spirit requirement unless it's already signed off. I am not saying focus on the negative simply let him know what your seeing and what he needs to improve on. If he really wants to be an Eagle then he will listen and respond in a positive way.
As for the Eagle Project it requires he shows leadership. He would have to put some thought into his project and lead the project which includes getting signatures for permission, photos, planning, etc... if he is as lazy as you say he is then that is where he would run into trouble. You as the SM can point him in the right direction but not do it for him.
I wouldn't re-test him on the things he is supposed to know (can tell you some stories of Eagles Scouts frantically running around the backcountry because the batteries in the GPS went dead). Maybe ask him if he needs a refresher on the stuff you see him lacking in.
The whole point of Eagle besides being the last rank is the fact that Eagle scouts are trained leaders.
