TC24 fuel tank capacity

So here's the question. 2005 tomcat 24 has a fuel capacity of what?

Written on the bulkhead by one tank it says 68 gals. So i assume thats 68 gals per side. I took a trip which ended up being 98 nm round trip and the fuel gauge needles pegged on empty. Aside from the pucker factor of making it to port, my simple math tells me I'm looking at 1.4nm/gal at 4800rpm. I am not impressed.
So off to the gas station to I go expecting a 60ish gallon per side fillup. The pump kicks off at 23gallons and I end up topping off at 25. Now I'm at 3.92nm/gal on a side(much better) and a huge question of how big are my tanks?? Is there any such thing as an accurate sending unit or fuel gauge?

Anyone out there with a same model year and size Tomcat mind sharing your tank size? Knowing will help set the DTE on my electronics and provide some better piece of mind.

Thanks in advance!
 
The Tom Cat 255 has two 75 gallon tanks for a total of 150 gallons.
Were your boat's tanks replaced? I know that some of the early plastic tanks leaked and they were replaced by aluminum tanks. I believe in at least one case, that the new tanks were smaller than the original. Of course the other question is how accurate is your fuel tank sensor? The amount of fuel used at 3+ miles per gallon sounds more realistic. A lot depending as to how much of the trip was on a plane, vs how much at displacement speeds. The performance numbers in the original brochure showed about 2.5 miles per gallon, just a little better than the Tom Cat 255 at low 2's.

The specification for the original Tom Cat gives tankage at 120 gallons.

I have the aluminum tanks. All the documentation that I have read never mention 68 gal capacities.

Thanks for the link Bob, great to read those write-ups from 15 or so years ago. The closest the article came was a 124gal capacity and even mentioned an option for 180gals.

I think before I pay that big pump out price, I will set my capacity at 60gals per side which will leave me a cushion (hopefully). I'll take along a couple 5gal cans and run it to the 60gal stops and see where I'm at. Probably won't take my wife on that trip.

Thanks again.
 
We have the 2003 and plastic tanks. I was told we had 55 gallon tanks and ran under that assumption for years. Then came along the ethanol fiasco and, once we decided to avoid that type of fuel at all costs, we siphoned out both tanks. On fill up it took 60 gallons both sides, a pleasant surprise though I still do all my planning as if we only carry 110 gallons. Boat fuel gauges are notoriously inaccurate and unreliable. With the early addition of independent fuel flow meters we are always confident of our fuel load.. We have never meet the nmpg factory spec and I have always been disappointed when we read of others stated claims. I have always attributed it to the fact that we run heavy. My trip planning assumes a 1.70 nm/gal and have never left us short to date. I'm always aware that the longer the trip the lighter we get :-)
 
I have Tomcat hull #2 and I have 2 - 45 gallon aluminum tanks. This is by far may biggest complaint about my boat. This weekend we are going to run from San Pedro to the Northern Channel Islands, which will require us to stop in ventura on the way there and the way back to be safe.

I get about 2.3 mpg on average and try not to push it farther than 140-150 miles round trip to be safe

I'm not very familiar with the TC-24, but how about adding a couple of saddle tanks?

Maybe of the bladder type inside the outer hulls about 1/2 way forward?

Just an idea........
