Briggs and Stratton 5 HP Help

[MIeagle]

Hello,

I have recently bought a briggs and stratton 5 hp outboard for my rebel 16'. One of the propeller blades is broken, but thats why I got to get the motor for $50. So I've been looking for a new propeller that is compatible. I believe it is a 8" diameter. Many of the propellers in online stores list the more popular engine manufacturers as compatible, should would those props work on mine as well? I didn't know how brand-specific they are.

Also, does anybody know where I could get a 1 or 2 gallon external fuel tank for this engine? Thanks for all of the help in advance.
