gasoline tank capacity

Recommended Posts

Hello, I recently purchased a 2019 297 SSX. When looking at the Garmin set up for gasoline tank size, it was entered as 109 gallons. The specs on the boat state 100 gallons. Is there a reserve 9 gallons in the tank, or was this entered wrong and should be changed to 100 gallons. I do not want to run out of gas in the water. Any help would be great.

 

Thanks,

Eric

Congrats on a beautiful boat.  Need pics at some point. 

It's definitely specced out as a 100 gallon tank but probably carries a few more when it's topped off to the max.  I would change it on your Garmin settings because that will alter the time and fuel left when your low fuel alarm comes on.  But try never to let it get that low anyway.

I have variable minimums.  Boating in refilling areas less than 10 miles away.   1/8 to a 1/4 of a tank. Going over that distance & might be going against a wind and or current.  No less than a 1/4 of a tank. 5.0L  V8 220 hp. with 6   200 pound people

set it to 100.  I have a 115 gallon tank and I set my Garmin Fuel Sensors on my head unit to 100 gallons.  I ran out of fuel the day after I installed these fuel sensors thinking there was more fuel in the boat than there was. Because when configuring my head unit, I ended up mis-calculating by 30 gallons causing me to run out of gas about 3 miles before reaching my dock.  Wasn't fun..

Congrats on the boat!!

 

The first basic rule on fuel is, "1/3 out, 1/3 back to home and 1/3 in reserve." Under that rule you will almost never run out.

One of my first days in boating it was a great summer day. The weather turned!  I burnt up more fuel fighting the waves and the wind and coming  back on fumes. Now I use that 1/3 rule.

The other tool to use,  "Gallons Per Hour" rate on our GPS. If you burn 10 GPH at 25 knots and you just put in 80 gals. Than it should be simple and just do the math.

If you have a GPH meter setup onboard ?  Do actual rpms in against the wind & currents. To see the rapid consumption at just off plane speed. And then on a full plane. Take about 6 people to really see your land mile distances.  You may be surprised.

Thanks for all of the replies. I set it for 100 gallons, and when I refuel it for the first time, I will go in and tell it it is full.IMG_0821.jpg.8d42d5466c000f8ca3294164a39ed44e.jpg

Sharp.  Perfect angle for that pic with the sharp bow and the windlass underneath and the squarish stern.  Very nice.
