I installed one of those flow meters in my boat a few years ago when the name was still "Navman". It was budget priced and it worked OK, at least for me. The only problem I have noticed is that after a number of years of use it is grossly inaccurate at low RPM (1000-1500 RPM), but at planing RPM still works great. I suggest you use it when still new to make your own fuel-speed-RPM chart by plotting values (you need a GPS for this) so that you can determine the RPM range that gives you the best fuel economy per nautical mile. Afterward, I'm sure you seldom will rely on it (at least, I don't). |

need to make sure it's mounted firmly(doesn't like vibrations) and properly(forget if input facing up or down), also make sure there is a filter before the flow meter. |

Can it be hooked up after my main engine filter or does it need an additional filter of its own? |
