Input needed on new boat

[River-Runner]

So I stumbled across this site and thought I would seek some "Profession" advise. I just bought a 19' Alumaweld Stryker with the 200HP OptiMax Sport Jet. I have been looking at used boats in the area for months and they seemed to sell used for around the same price I paid new. I actually bought the boat below the dealers cost and got the 5 year warranty. Alumaweld quit making the 19' and I am not sure why. I have been running a 17' sled with a 55hp Jet but time for something bigger. From what I can tell, this boat flat out moves. I plan on keeping it forever and would like feedback from somebody else who has this setup. Do's, dont's, anything that will help me get the most out of this boat. Thanks People...
