how do I make my 2000yr 1800 challenger jet boat single jet got Faster?

[thekidstuff]

would like more top end speed only at 55mph right now

 

[rookie101]

55mph is really good for that boat. If you need or want flat out top speed look into a stern-drive boat with 500-600 hp. anything over about 65mph should cost in the neighborhood of 100,000 dollars.
