Question
Brison 4.2

Hey all,

A friend of mine picked up a New Brison 4.2 for a steal however he is unsure on what prop to use and what to expect. It has a gold block.

Does anyone out there know what size prop to run and what sort of RPM to expect. He's currently got a 24x8 on it but hasn't fired it up yet.

Cheers,

Glenn.

I use a 22X10 on my Sachs 4.2 @ around 7000 RPM.
