Hey all, I have a 195 Horizon Cuddy (1985) and the fuel guage is erratic (go figure). I filled the tank to capacity yesterday and we were out on it all day (running wide open for long stretches). Does anyone have an idea as to the size of the tank? Also, would a bad ground be a good cause for the INOP guage? It bounces around and sometimes reads and then doesn't. Odd. Thanks |

You have a 27 gallon fuel tank in your boat. Some gauges are just not accurate. On every boat I have owned I have installed a fuel flow meter because I did not trust what the gauge was telling me and glad I did. Our cruiser had a 75 gallon tank. It would show 3/4 full until there was 13 gallons or so left and then go down very quickly. Just think how much jostling there is on a boat with haves and such. |

buy another fuel gauge and mount it somewhere. I was going to do that until I got our gauge in the dash fixed. (I already tested the sending unit and it was good) I might just be time to get a new sending unit. That is where I would start. |

I have never really had confidence in any fuel gauge. Even airplanes are only required to read accurate when empty. With my last boat (about the same size as yours), I would fill up after two days of playing on the water. Didn't matter if it was most of the day, or just an hour or two. With my FW, I use three days as the rule... same principle. When skiing/tubing, etc, you are usually running just above planing speed, which if actually very economical in boating terms. It's the long, high speed runs that suck down the go-juice. I know it's not accurate either, but I do have more confidence in filling up every other or every third outing than wondering when my gas gage will fail and not tell me. |

Walt, I don't know what airplane you're referring too, but I know from experience that during annuals or calendar insp. different A/C mfg's require more then unusable fuel calibration checks. Maybe the puddle jumpers don't have that type of checks but turbine type rated do. |

What is the easiest way to test my sending unit? |

The "potential" inaccuracy of the gage was pounded into my head thru flight training. I was always told "they're only right when they're empty". I put the same sort of credibility into my boat fuel gages. |

I put the same sort of credibility into my boat fuel gages. I have flown a lot of aircraft in my time and generally find the fuel gauges to be pretty accurate. However since you are in the air and gas stations are a little scarce up there you should do a visual check of your tanks before you take off. Proper flight planning also dictates that you calculate your fuel burn and make sure you have at least 45 min of reserve fuel for flight beyond your destination Same should apply for your boat. Do a few trips out with full tanks and fill them back up after your day on the lake. If you take an average fuel burn of your days outing for the type of boating you do, you should have a pretty good idea how much fun you can have before filling the tank. |
