Fueling on trailer

I have a 23’ Seacraft with a 146 gallon fuel tank and I’m having a problem getting the tank full on the trailer. I’m wondering if this is a common problem with others. The tank is behind the console on centerline. I have the trailer about as level as I can get it.

How are you determining how much gas you need to be full? Could be your gauge is off or if you have a meter it may be showing a higher fuel burn than actual.

I’m going off the Mercury smart guages which give percentage full, how much burned and est. burn rate for speed.

If you are filling to the point that fuel comes out the vent you are probably full. I have no idea how to check / adjust the smart gauges.

I would trust the fuel dispenser over the gauges any day. With the boat level, you should be able to fill the tank to nearly 100% of it’s capacity.

Especially with a Quality boat like a Seacraft. Does the boat look level on the trailer? If so, it it likely full.

I’m reading the manual now. Last time at pump I did fill till gas came out vent.

Went through manual recalibrated guages got it to read gallons and percentage. It says I have 111 gallons of fuel and that should be about right from my last trip out for fuel used. Will check tomorrow night when I fuel for fishing Saturday.

I went through the same thing with my SmartCraft gauges. My boat holds 215 gallons. I would fill it up but the gauge said 145 gallons. I knew it was full because gas ran out of the vent. I finally figured out how to recalibrate the gauge. Now it works perfectly. The fuel burn is very accurate on my gauges.

Not an expert, but I remember the folks at the dry stack marina often state that you can get an air pocket in tank that can trick you to think it is full when it is not. I would think the only way to overcome that or to make sure it is not happening is to wait a little bit once it is topped off and top if off again, but don’t fully depress the fuel and add it slower.

All in all I agree with the rest - I would trust it was full by it coming out the vents v. a gauge any day. I feel for you, scary feeling especially if you are heading offshore.

Everything went well after calibrating guages. Went out to 200ft on Saturday gauges said I burnt 50gals went to pumps on Sunday put 40gals in and gauges read fine. Thanks for everyones input.

Had an airpocket Saturday and that sucker spewed gas out all over the boat.
