If you want a Yamaha with a P-bass sound, I would recommend a BB. Of the current line the BBP34 is the nicest for passive-only at around $1500; the BB734A is the most versatile choice at about $750.
Amazing blue on the BBP34:
Historically, you’d want to look for a BB1024X, 2024X, BB2000, or BB1200/1200S. These will be expensive used, probably as much as a new current model.
The motion bass line that Al recommended is also awesome. Really cute medium scale bass. Probably sounds a little less like a P and more like a standard P/J though.
I really love the SBV-550 but the looks are not for everyone; generally it’s a love/hate thing. But the tone is incredible and the quality is through the roof. This one looks pretty much identical to mine:
