i purchased a genesis cat with a new liquid cooled 4074 leopard motor, i ordered a turnigy 180a marine liquid cooled esc. now this may be a foolish question but which should be cooled first the esc or motor? i'm all new with this boating thing but after watching all the vids on my setup and reading the forums i think i'm gonna have a pretty fast setup. also how do you measure props, i have no idea what i have for a prop.
