Does a trolling motor or a baitcast reel qualify as "machinery"?
Lol
No it does not. Machinery would be something that burns a fuel (generator, inboard engine)
For an outboard-powered boat the requirement is the fuel hose you use must say SAE J1527 on it. If it says that on the hose you are good to go, if not, then the hose is not compliant.
Others have said to use A1-15. While that is not technically incorrect by any means you may find A1-15 to be a little bulky or stiff if your application. You can certainly use B1-15 in its place, which will be less bulky and more flexible. Without machinery, you do not have to worry about the fuel line passing the burn test, which is the difference between A1 and B1 fuel lines. A1 will pass the 2-minute burn test, and B1 will not. Hence the question about machinery.
