The Nitro Bay 1900 Tunnel 2005 carries a rated maximum of 150 hp. Engine data for the Nitro Z21 2021 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Nitro Z21 2021 carries 55 gallons versus 47 gallons in the Nitro Bay 1900 Tunnel 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
