Gas Gauge

9 posts in this topic

The gas gauge on my boat does not read properly. When I fill the tank up the needle goes way beyond the Full line. When I bought this boat a used (2001 Lund Pro Sport) the guy never told me about the bad gauge and I ran out of gas eight miles out on Lake of the Woods because when the gauge reads a little under a half a tank your out of gas. Is there a way to re-calibrate the gauge or do I need to buy a new one? How do you install a new gas gauge if I do need to?

Thanks!

The problem probably isn't the gas gauge - it's the sender.

You can buy replacement senders and probably have better luck bending the length of the sender yourself and get a little better accuracy.

How do you reach the gas tank? I believe it is under the floor in my boat? Any tips in how to chsnge a sending unit?

Duddly, I believe it's under the center panel in your floor. You just have to pull the screws out and lift the board. Replacing the sending unit is very easy- remove the wires connected to it (write down EXACTLY how they're connected, don't try remember it- draw a diagram), remove several screws, pop out the old sending unit, go to a marine dealership and get a new one (bring some lube, because it's going to be way more pricey than a little unit like that should be), pop it in, put in screws and wires- viola!

I believe the floats on them can go bad- does anyone ever just replace the floats? I assume you're generally better off replacing the whole unit since you're in there, huh?

I'd replace the whole sender... 95% of the time it's the sender itself and not the float - and if you're going to open up the floor and mess with it I'd just as soon replace it.

I'm having the same type problem on my Smoker Craft. It shows full when I fill it but stops going down once it gets down to half full. I hope I have a center board with easy access. confused.gif

RonZych,

Check the floor in your Smokercraft for an access cover. Mine's right over the wiring to the tank. No need to take out the centerboard.

      My garage roof is leaking from last few weeks and i am very much tensed about it because i have tried many things to block the leaks but nothing can prevent it.So i must call Roof Repair expert for this or is there any way to prevent those leaks.

      Thanks. So it hasn't changed much then. Still might go give it a whirl!

      If you haven't read it yet, a couple of slobs are about to ruin it for the rest of us. Pick up your garbage and respect private property. The land owners who allow access to the lower sucker river are about to shut it down because they are so fed up with it. http://minnesotasteelheader.blogspot.com

      With the wind being fairly strong today I opted to hit the back waters of Little Rock. Have done goid there in yrs past.... so I figured it would be worth a shot. Finding crappies was pretty easy, they were holding tight to the brush and downed trees. Finding crappies over 8inches was tough...lol.  I don't think I broke 9inches. But did manage one big carp. Guessing right around 30in, pulled me and the yak all over the lake before I got it boat side

      Hit the one down by Watkins a couple times this winter. There were a lot of people that fished it this last winter. Got gills and crappies of all different sizes. If your looking for keeper size fish, other area lakes will provide better numbers. Haven't been on the other one of  in a few yrs. There were good numbers of 6-7in sunfish if I remember right.
