McMaster-Carr or Grainger.
Consider using a cog belt, as high speed chain drives are noisey and will sling their oil off. In addition, the high mass of the chain will apply a lot of extra tension during operation, straining bearings and eventually streching the chain.

Hi, i am designing a drive system for my Arthur Robb yawl. Based on a choice of a mars brushless 48v motor and my existing prop, i should need a 1.5-1.75:1 belt or chain drivetrain.
my question is, where do i find one? I have tried Sea-EV, but no answer. Does everyone just build their own with industrial bearings and shafts or is there some place where various ratio drives can be obtained?
thank you!
kenneth
