I should probably post this since I'm sure there will be other people looking for this information in the future.  These are the 'factory settings' for a 177 Marauder Field and Target (regulated) according to Crosman customer service.  Direct copy and paste from the Email I got from them…

 

Thank you for contacting Crosman.

Unfortunately the regulator in your Marauder should not be adjusted by the customer. Digging deep enough into the gun to get at it would void your warranty.

The gun should also not be fired under 2000PSI, or you will experience increased accuracy issues.

Here is the available information you asked for according to our engineer.

Striker (hammer stroke) at 12 turns in.
Hammer spring preload at 6 turns in
Valve screw 4 turns out
Reg setting at 2050 PSI.

I do advise against adjusting any setting other than the hammer spring.
