I'll have to double check the GPS. It read 56-57 mph for a good 10 seconds. Maybe the outdrive gearing is different. My boat easily beats my neighbors 2003 Yamaha GP800r out of the hole and top speed. |

Good thing you figured that out. Just think of how much differently you'd view things if it only got up to 54 MPH. |

I can hit 52 at the rev limiter! Then again my home lake's only about 3 miles from end to end, so top speed isn't that important. |

Maybe a previous owner had substantial modifications done. If it's injected, a reprogram of the ECM, a larger throttle body, a set of injectors to handle a larger pulse width and a bigger gear in the drive, then 57 isn't out of the question at all. John

Spotting something not quite acurate here. I am going for driving down the road or its set for kilometres per hour |

Actually both Garmin and Lowrance marine GPS's I have read 1-mph higher than the speedo apps I tried on the iPhone. But either way, I had a 2006 3.0 VP H180 (first boat when I moved to TN), it wouldnt do 40mph if I dropped it out of an airplane here at 1400' elevation with a full tank and two adults. |

Exactly, and maybe "45 ish" means 39.867 mph ???? No way in hell it does 45 mph with a stock 3.0L and that sterndrive. I have had good luck on my Android phone with the Speedview app. I have checked it on land, and compared it to 5 different boats with either Garmin, Lowrance GPS on board. It's quite accurate, for me at least. iPhone may be the culprit indeed. |

Empty boat, 1/4 tank gas, just me (190lb)... Glassy lake. 50ft above sea level. Low 40s. It runs great. RPM's were in the 5100 range. |
