For maximum maneuverability the steerable kort installed similar to Scoot, Mustang Sally, or my boat is probably the way to go. The trade off for using fixed nozzle is the ability to accurately fit the prop tightly in the nozzle potentially increasing efficiency.
My understanding of the rule book is that competition boats are not allowed to use kort nozzles. My boat has a keel a bit longer than Scoot's and the wheel is smaller diameter so I am not able to achieve the same level of maneuverability....yet. In addition, my rudder is close to the waterline and if I apply too much power in reverse, the wheel is able to move enough water to actually make a little whirlpool and sucks air down the rudder cavitating the prop. I dare not operate in shallow water as small pebbles are easily sucked through the nozzle. It sounds like ice in a blender when this happens.
Best regards to all!
