When I bought my boat in April it had no power. I went with 575s, Boat came with water pickups for superchillers and scoups on the hatch for the added height of the chillers ++++++ waaaay more bling factor with the little whiners up top. Should be done in the next couple of weeks I hope..Mike

575's need 91 octane or higher.
