Trying to identify switches on 1975 Century Trident

[musicexperience]

I am restoring an old 75 Century Trident and I am trying to identify the switches. I recognize the starter and I am assuming L=lights and B=blower, but I don't know what "MP" means. Main power? Momentary power? The wiring harness has been butchered and my Mercruiser schematics obviously don't get that detailed into the dash. I am sure it's something simple that everyone knows but me. I appreciate the help!
Thanks!

How about "Macerator Pump"?

What engine and drive?

It had a Mercruiser 165 I/O that I have swapped out for a 140 4-banger Mercruiser. I think the difference in weight between the two will definitely make up for the 25 missing horses.

It doesn't have a head on it, but that would explain why the wiring from that switch was hooked up to the old bilge pump. I bet that's it! Thanks!

Manual Pump - it turns on your bilge pump.

Okay, then want does the BP do? Turn on oil leaks?
