We had a 2003 30' Phantom pleasure boat. The boat had around 900HP. 600c.i., 3.3 whipple. We set it up with a IMCO 3" shortie, and hydro 5 blade. The boat ran better LH than RH. We consistently ran over 110MPH, and the fastest we saw was 114 w/ 4 people and ice chest. The boat drove like it was on rails.
