Can I open an EMM?

I have a problem with my EMM. It overheated because of a bad battery and the engine doesn't start any more. I read that it could be just a blown fuse. So I tried to open it myself to check the fuses, but after unscrewing the top, I cannot lift it. It seems stuck with some tape inside. I used a stanley knife to detach around the edge but still nogo. I am afraid to insert the knife too deeply as I guess I may cut some wires. 

The reason why I am trying to fix it myself is that I live in Mauritius, in the middle of the Indian Ocean, and sending it in to a US repair service costs me more than $200 each way. 

Any tips?

Cheers

Silvano

Usually those things are potted inside. To keep out moisture and cut down on vibration, I could be wrong though about Evinrude, but I know when my Yamaha went I cut it open to see what I could find and it was all solid rubber

On a FICHT engine there are no fuses inside the EMM. They are located in the power distribution panel on the stb. side of the powerhead. Coming off the PDP is a wire that is attached to a 20 amp fuse holder that feeds the EMM. Sometimes corrosion gets inside the contacts and the result is a poor, intermittent, or completely open connection. The PDP fuses are for various items and are all 10 amp.  It is best to obtain a factory service manual for your particular engine for an accurate reference.
