Hi, I had the first ride in my recently bought Vista V258 2008. There is Volvo 5.0 engine installed (270 hp) and I wonder what is the optimal cruising speed/RPM on this bought with this engine? I was driving it on 3500 RPM and it was ca 27 mph. Thanx |

That should be the sweet spot depending on load. |

There are plenty of other factors, such as weight of the boat, HP, gearing and props. I don't know enough about your drivetrain to give you an answer. |

The 5.8 @ 4000rpms should be 35mph unless you're hauling a few tons of load. 15x17 stock prop. |

I have a V258 also, a 2007. At 3500RPMs, roughly, the boat will do 23-26MPH depending on how choppy it is. Also thats at 10GPH with a 1.9 to 2.2MPG fuel flow. |

Yeah they're a bit happy with their spec sheets. I know on my H180 it's pretty much 100% wrong. |

You callin' them a liar?? Again, or at lest in the "real would." That like believing that every car in a showroom, with a MPG rating on it, is what you are going to get after you buy it. You could, but you won't. |

According to FW my H180 with a 3.0 and stock prop should do 36mph @ 4000rpms. With a 20mph tail wind, 50ft above sea level, trimmed perfect.. the best I can do at 4000rpms is exactly 30mph. I am running a Solas prop stock pitch that is 2mm bigger then factory so technically it should be spot on. To be 6mph off spec with a perfectly running boat tells me one thing... prop slip with the cheap solas. Or bad FW specs. I'm thinking prop slip. I only get 2-3mph from 3500 to 4100. If I keep this boat I'm going to have to upgrade to a better prop. I'm 6-7mph slower per spec across the board. |
