1990 PROV 150 Lower Unit

[ChevyDonzi]

I have a 1190 PROV150 outboard. Model PROV150LD serial #351900. I'm trying to get a replacement genuine Yamaha Lower unit. I've found a few for sale, but I'm wondering which part numbers are compatable. Yamaha Parts website says I need part # 6J9-45300-12-NA
I'm wondering which others will work. I've been told by a dealer that 6G5-45300-13-EK will work, however they didn't seem very confident.
Will 6G5-45300-17-8D work?
Thanks
