Ok I hooked up my battery to my 25 hp mercury outboard with electric start and hooked the wiring harness to the boat to test some lights and noticed I had 2 wires touching, and nothing seemed to work, thinking I blew a fuse the only fuses I know of are the inline fuses between the radio and lights, those are fine, I hooked the battery directly to the boat wiring after the ignition and all the electronics in the boat work fine. The boat does have a kill switch so I checked that, my question is, is there another fuse somewhere? Maybe in the engine? I have nothing when hooking battery threw the engine.????

Also I used to be able to crank the engine but I get nothing now.

most newer engines have a fuse under the cowling useually right at the starter

The 25 Merc's have an in-line fuse under the cowl.

The diagram should help you locate it.

Ok I found a fuse holder it was mounted to the back near the plugs, I opened it up and the fuse came apart, now I have both halves stuck in the holder. Does this sound like the right one? The fuse holder looks to be coming off the wire harness inside the cowl.

yes sounds right but what do you mean the two halves is the fuse broke in half?

Yes when I pulled the fuse holder apart the glass piece on the fuse came off and left the metal end in the other half, I put some wd40 in to get it loose.

just replace the fuse and you should be good to go.

95 cents later all good!!!!! Thanks!

Don't forget to carry at least one extra fuse with you when it's done!
