Name that module

[IDoSeaDoo]

Hey guys, I'm working on my '97 Challenger 110. Does anyone know what the black module under the dash switches does? It's held on by 3 screws and has a big harness going into it. You can see a relay and a bunch of fuses embedded in it too. I'm curious as to what it's for. It's not an MPEM, but it looks important.

It runs the bilge pump, blower, nav lights, etc.

Are those switches not strong enough to do that on their own?

If it's #37, it's the fuse block. Just like the one in your car, you never run an accessory unfused.

Yea, that looks like it. I wonder what the relay is for, I was going to run all but my 8A bilge pump of just the the switches, including a small 360gph bilge pump for regular use. The nav lights will use small led bulbs but the blower motor and bilge pump will be the same as oem. Btw, anyone know if the "silent" blower motors that Sierra puts out now are any more silent than the old stock unit that came on this boat and doubtless all others of that vintage? I find it rather loud but anticipate running it quite often to compensate for that 4tec heat soaking
