Re: [Electric Boats] 1.5:1 drivetrain help

I agree. The gear-box is a better option.

One should consider the browning gearbox as well, as used by James at
Propulsion Marine.

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.

Be Well,

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!
