Alright guys I finally got back around to getting the serial number off the engine (right behind the dipstick) but I'm having trouble trying to decode it. I'd appreciate some help on showing me what I have for sure for an engine.

It looks like to me P-644685 and then beside & below that it looks like 88 5
