Additional fuel tank

Wes · Post by **Wes** » Mon Jan 21, 2008 8:03 pm

I have a 1983 Flybridge/aftcabin that only holds 200 gals. of gas. She has twin 454's and they love to suck the gas up. Has anyone who has one of this model ever put in a reserve tank? I'm not sure where the heck one would put an additional tank but I'd love any ideas.
Thanks.

Wes you don't say what length your boat is. My 1980 F-36 has provisions under the cockpit floor for two round additional fuel tanks 50 gallons each I think. This was an option Trojan offered on the 36's.

Hi Danny,
Sorry for the omit. It's a 10 meter (33') with a 13' beam. This boat is so crammed with stuff I don't think it's possible to get anything else into it but I thought I'd ask.
Thanks,
Wes

What year 10 Meter?

Is it a midcabin, express cruiser, aft cabin or convertible?

If she is an 10 Meter express cruiser without the midcabin you have a tremendous amount of room below the rear cockpit deck, outboard of the factory 242 gallon tank.

You could have two custom made aluminum tanks mounted there.

This was something I considered before doing my repower to diesel.

If you do this you should consider increasing the size of your tabs.

Hi RWS

It's a 1983 10 meter flybridge/aftcabin. I'm carrying 2 - 100 gal tanks in the aft cabin under the bunks.. This baby is full!

Wes,

You have a lot of boat, a lot of weight and not much space.

I have been on one aft cabin 10 Meter, but not a flybridge model.

As I see it, every inch of space was used with that design.

Based on the weight issue, you might consider replacing your tabs going from the factory 9" to 12" with a drop fin.

If you have Bennett tabs, they make a direct replacement.

When I was still running the 454's this made a big difference for me in my Express Cruiser.

I don't know how your running angle is with all that extra weight aft and with the flybridge added, which might balance it out, but if you need to improve your running angle, this would allow you to get the ass end of the boat out of the water better and improve your running angle.

All this equals more effeciency which would improve your range.

I had my 10 meter up to .8 nmpg at a speed of 15 kts with the 454's (veirified with a digital tach/sync, flowscan & GPS) which is not too shabby, considering the volume of the boat and the hull design which while extremely good for sea keeping properties, is not the most effecient mileage/range wise.

Thanks RWS,

I know. She's built for comfort not economy. LOL, but I love her just the same.

I have a 1982 10 meter with Aft cabin. I have no idea how to get one of the 110 gallon fuel tanks (it's leaking) out of the aft cabin.

The only way I can see is to remove the whole roof of the aft cabin.

I would suggest first contacting Beacon Marine or Marine Tech.

Might be a good time to pull both tanks.

Can't be too safe with gas.

The previous owner of our 1983 10 meter flybridge/aftcabin had the tanks replaced by the yard before we bought ours. They had aluminum tanks made that would fit through the door into the aft cabin. The largest they could have built were 100 gallons each. I would bet the best way to get the old tanks out is drain and clean them out and cut them up. Good luck and keep us posted.
