I just bought a 15' flatbo
I just bought a 15' flatbottom that came with two Mariner 30E outboards (one on the boat one spare). They both say made in Japan so I assume they were made by Yamaha but I cant figure out the year...Ser #s are 689 410922 and 689 409221. No letters in between. I can't find reference to them online. Can anyone help identify the year model so I can get the proper manual.
