Replacing 15 yr old Ample 200 amp alternator

My boat is equipped with all of the circa 1999 Ample Power stuff -- 200 amp alternator, Next Step Voltage Regulator, Eliminator, & EMON II. For 15.5 years everything worked great so no complaints. However yesterday I'm pretty sure that the alternator failed. If I decide to replace the alternator with a new one from Ample Power, which model do you recommend for the easiest R&R and to match the older components? I can't seem to find my old receipts and don't have the model number readily available as I haven't unmounted it yet. Back in 1999 I think there were fewer models to choose from. Engine is a 140 hp Yanmar diesel. Thanks.

Typically a Yanmar engine would use a #4023-S unless there was custom brackets made for a 200 Amp alternator.

Can you post a picture?

I found some old paperwork where I had highlighted PT60. Does that designator mean anything to you? My mechanic took the alternator off of the boat and is testing it at his shop so no photo available right now.

OK, that would be a #4060 replacement.

Are new 4060's available at this time? Your online store seems to indicate that they are not. If they are available, what would be the price for one. Thanks.
