Carver Owners Forum

I am trying to get a definitive answer on fuel tank capacity for my 1998 Carver 355.

In my research I have come across the total gallons as 318 (though sometimes as 320) gallons. I do have the aft aux tank which I see references to being 120 gallons, and then the port/stbd tanks at 100 gallons (of course this equals 320 gallons, not 318) though sometimes the port/stbd tanks are listed at 99 gallons (which would give 318 gallons).

I do have the owners manual but it is not clear on exactly what is what, thus my question. Any help would be appreciated!

I believe the official tank capacities are 100 for each side tank, and 118 for the aux tank. That's what we have found on a boat that we had to replace the tanks in.

Thanks Ramsport47.

I would be interested if you learn anything more on this.
The way I understood it when I bought my boat was that the two side tanks were each 125 gallons and the rear (aux) tank is 68 gallons. I believe this to be true, although I have never run the side tanks out and the aux tank has always been empty since before I bought it.

If you really want to know the tank volume on any boat simply measure the tank width x height x depth to come up with total volume and divide by the volume one gallon of water takes up. I bet the volume of a gallon of water can be found on the internet.

yes, it's 231, although you have to account for rounded corners or odd shapes, that only works on square and rectangle shapes
