Any advice welcome. Thanks!

Call your local Yamaha outboard motor dealer, they'll look it up for ya.
Question for you..... I have a new Honda 8hp outboard. After buying it I let it sit for like 2 months before I started it. After that I found it was pretty hard to start initially... I might have flooded it though, but it took like 15 pulls and nothing... Then I waited 5 minutes and after that it started in about 5 or 6 pulls. After I warmed it up and ran it, it started without hesitation on the 1st pull. I was thinking that is normal when they sit for awhile. Have you ever experienced that with yours?
