Sorry to hear that you bought a Dolphin. I wouldn't waste any more money than possible with that boat unless you can use the stuff later on when you get a good boat.

Seriously, we wished that you found this site before dropping your money on that boat. You saw it on eBay and was impressed that it said that it would go 55-65 MPH and it was cheap.
go into the Nitro forum and then use the seasch at the bottom of the screen. Enter the word "Dolphin" in there then read the postings on it.
