I've got a brand new Yamaha VF250LB lower unit for sale. This was removed from a new 2023 motor for a jet drive installation. 0 hours, has not been in the water, has some light scuffing/scratch on the port side from handling/storage.
Fits 2010 to present VF200/225/250LA + LB models. These go for $4,760 + tax from Yamaha. Selling for $4,200 + $200 (insured) shipping. 6 month warranty. Note - these units may be backordered and take a month or so to get from a dealer, so here's your chance :)
