After departing the ramp dock, I usually select a level of No Wake Mode 1-3. Once I'm cruising, I match the rpm's of the engines, as cruise control does not balance them, and then turn on the cruise control.
The boat does not handle like a bass boat. I know it looks like it has a rudder, but it doesn't. No power, no control. However, you have separate control of each jet. You can spin on a dime by putting one jet in forward and the other in reverse. You can even crab walk because of this. It just takes the right input of steering with the jets opposite.
For docking, with minimum forward thrust, driving at angle into the dock, SLOWY, as you get close throw the far side jet into minimal reverse. That will swing your bow away from the dock and slow your forward progress. When your close and parallel, turn off the engines and tie off. If you can, approach from the leeward side, so you don't get pushed into the dock. In other words, like on your bass boat, take the wind and current into account.
Good luck. Enjoy your new boat. Glad your on a little lake without a lot of influence on your boat.
