1990 22ft CCP fuel tank ???

[Adam927]

The fuel tank in my boat needs to me replaced. It is leaking and I think there is a problem with the pickup. What is my best option? Aluminum, plastic etc? It has an 85gal tank in it now, however I am repowering with a 1999  250hp Johnson ocean pro. Do they make a 100gal tank that will fit in the same place as the 85? Would I need more than 85gal?

Welcome Adam! There is an entire section devoted to fuel tanks.....most everything u need to know is in there, just search the forum.

Adam,
The coffin in your CCP has a little extra room in the rear so it may indeed be possible to fit a few extra gallons on board. Most members seem to gravitate toward aluminum and if you want to add additional fuel, the tank maker will build to suit.  The poly will work but you are somewhat limited in that you need to fit the dimensioned tank into your existing coffin.

Depending on where you hang your hat, there are several tank fabricators that have build OEM tanks for Aquasports and they have the factory specs. I replaced my 100 gal. tank with a 55gal. Same dimensions just shorter in overall length. You would go the opposite direction with your 85 by increasing the length.

Measure your old tank and the coffin. I can't recall but I'm thinking there is a foot +/- additional you can add.

Read the thread I've linked below and you'll get some ideas on the different sizes used on old Aquas. Wingtime's 200 tank dimensions should be the same as yours, only slightly shorter.

If you would, after measuring your 85 gal, post its dimensions here:

If you go with a bigger tank, posts those also. It will go a long way in helping the next member.

Thanks and good luck.

I just removed my 85 gallon tank a couple of weeks ago. It was a close fit in the coffin. There was maybe 3 inches of space total around the tank, about 1.5 inches on either side and ends. Ill measure it and the coffin and post it up....

I don't believe you will be able to get a much bigger tank unless you modify the coffin itself.  Only you can answer if you'll need more than 85 gals, ask yourself what your typical outing & distance will be.  The calculation for estimated gallons is the following;

Length x Width x Height, then divide by 231

[Capt. Bob]

I think you're both correct. 

It's been so long since I replaced the tank in the CCP (6 years prior to the site start up) I'm probably mistaken on the space available. Looking at a few of the tank replacement threads also seems to indicate this.

[Adam927]

Thanks for all the info. I have not yet removed the deck plate to access the tank. But I will post more when I have time to dig in. Thanks!!

I would like to put a 100 gallon tank in my 1990 Aquasport. It has an 85 gallon tank in it now. Anyone know if one will fit in the tank opening? If not I could always just go back with the factory size.

[Capt. Bob]

Going on the assumption that it is a CCP, it would appear from the responses above that you do not have a lot of room left in the coffin to increase the tank volume. 85 gal. has seemed to work well for those (myself included) who have ran this model Aquasport.

Good luck.

[Adam927]

No there is not much room around the tank at all. A few inches at best. My issue is that I am putting a 250hp motor on it which I am sure is not very fuel friendly. I intend to fish offshore up to 35 miles out or so. I'm not sure if 85gal will be enough fuel. I want to be able to troll around as well.

The answer lies back with Blue Agave's answer, yes it's possible to put a larger tank in, but...you will need to have an idea of how much space is open under the coffin box the tank sits in now. Then figure how much more depth you would get by removing the coffin box. You would have to add a new floor piece under the sole to hold the tank up allowing for approx. 2 inches for water travel under it for drainage, bulkheads at both ends to keep it in place and a way to strap it to the stringers. Example, lets say your tank measures 84x21x11, that's about 84 gallons( I'm not sure of the size of a CCP tank) if you can gain 4 inches in depth on the entire tank making it 84x21x15 your looking at 114 gallons..Doable  but you will be doing some modifications under the floor to do this but its very doable if you have the space...Just my .02

 Did you CCP have the original 200hp motor on it? I have never had this boat offshore so I have no idea what fuel economy will be like. I blew up the 200hp that was on it on my first trip out the inlet. lol The fuel pickup or something is bad and was starving the engine for fuel. I forced it to run by continuously pumping the ball and ran it lean and created a main bearing problem. (Squeaks badly) still runs barely. lol Now I am putting a 99 johnson 250hp 2 stroke on it. So I really have no idea what the fuel economy will be. Do you think 85gal will be enough to run 35 miles off troll around and run 35 miles back??

Adam,

Let's address the last two posts.

First Gman's:

Photos taken by sticking my hand down the bilge acess shows that the tank bin rests on the keel... thus there is a nice void next to the keel.



This is a photo of a member's 78 200 CCP. The quote above is his findings.

I'm betting you will find the same thing in your hull and if so, that leaves you with only lengthening the tank to gain more quantity. You would again have to alter one end of the coffin.

To answer your last post, my 84 222 came with a 185hp motor. I replaced it with a 96 200hp. I liked to dolphin fish and runs would often be 20-30 miles one way. The 85 gal tank was fine in my case. The old rule of thumb (and proven with my Flow Scan) is 10% of your rated hp at WOT. so about 20 gph at 5700rpm. That would be just under 41 mph on the GPS. I usually ran around 4200 rpm and burned about 11-12 gph at about 28 mph.
This is all average with sea conditions and load and often I would run a little slower (3900-4000 rpm).

Your old 250, if tuned correctly should burn about 25 gph at WOT. Properly trimmed and with the correct prop, you may run 50+/- mph (maybe not too). Point is, if you just "cruise" to your fishing grounds, you will burn less. You may get an average 2 +/- mpg with the right conditions. The 250, probably has a greater displacement along with carbs to feed it and it's heavier too. All of this is guideline talk and as they say, your mileage may vary. For my use, the 200 was just fine but I'm assuming you're getting a deal on the bigger motor.

I can tell you this. On long hauls out of Everglades National Park, and out into the Gulf, I carried 33 extra gallons on board in a poly drum. May be another way to approach your problem.

Good luck.

Adam are you the new owner of "Fish Mortician" that was bought from Carteret Comm college...

[Adam927]

Yes sir I am indeed the new owner of said boat. Soon to get a new name. Lol
