What type of Alternator on Volvo Penta 5.0 Gxi?

Have a 2007 Rinker 300 ec and am wondering if our alternators are GM 1 wire alternators or have external regulators?  If I was at the boat I'd just look for myself, but I am not :-)  I'm pretty sure they are 70amp each as well.  Please verify if you know.

Thanks!

Went to alternator shop today and they looked up the alt by part number... The 16 gauge wire that's going into the back of the alternator is for ignition on and the second wire is a dummy wire for this particular model.  So no external regulator and explains why both of the second wires are cut.  Answering my own question gradually this week :-)

went down and took some pictures. Trying to figure out if these alternators have advanced regulators attached to one of the wires or if they are just simple one wire alternators. There was one wire in the back plug that was snipped off intentionally on each side. any idea what that's all about?

Do remember that you need a marinized version NOT just a GM replacement. All engine bay components relating to gas, fire, spark must be Coast Guard approved - for you and your passengers' safety - not to mention your insurance.
