Marine Carbs

"A marine carb is designed for wide open throttle (WOT), generally has poor transient response. An automotive carb is focused on transient response for good drive-ability. Marine carbs generally do not work well on the street. Some people compensate with a really loose torque converter (like 5000 rpm stall). In the water, the water provides a lot of slippage - on the street that does not exist."


A response I found here.
