Trim....
As your boat sits, the only thing you can adjust is your ride plate at the back. This can help if your boat tends to porpoise, but will not keep the spray out of your riders face.
There is an after market solution built by the Scott Waterjet Company. They make a hydraulic trim nozzle for the Mercury Sport Jet, but they will cost you between 1500 and 2000. The US distributor is Schlagel Marine. Google them or Scott waterjet Nozzle and you can find all the info you need.
