Fuel tank size on 1986 23 outboard
 

I picked up a 23 outoboard and ran it this summer. I had problems fueling it up. Could never tell if tank was truly full. Gauge is obvioiusly off. I was told it holds 125 gallons but not sure and don't like spilling fuel or running out as means to the answer. Anyone have an '86 or know the answer. Thanks

Larry,

Welcome to the site. I have an '89 23 CC w/ 200 Yamaha. I replaced the tank this spring with 133 gal. aluminium from sptanks.com. They built to my specs and coated with epoxy. Nice tank. Included an electric sending unit installed.

My tank was foamed in and had several small leaks where the foam was touching. The fill tube was cracked and leaking as well.

Length x width x height / 231 = volume in gallons

(Measurements in inches)

The new tank is roughly 28" wide x 11" high x 116" long outside. If I did it again, I'd make it smaller and shim it in for better air flow.

Using Scott's formula, Otto's tank comes out to 154.66 gallons [img]images/icons/confused.gif[/img] .

Interestingly, sptanks certified my tank at 133 gallons...

Salty Dog had hair in that picture. Last weekend, he was working with 2 part epoxy and got some in what hair he had. He had to shave his head to get it out. Too funny...

Otto ...Thats interesting ... even if you use SPTanks volume calculator with your numbers its still 154.66....wonder where 21 gallons went??

same width and height and 99" long gets you to 132 gallons

After all, we are fisherman here. You know how things tend to get longer/bigger the more you tell the story... [img]images/icons/wink.gif[/img]

OK - how did you guys empty your tanks and what did you do with the premix?

Hey Scott M

"After all, we are fisherman here. You know how things tend to get longer/bigger"

I'm been telling my wife this for 30 years! [img]images/icons/grin.gif[/img]

John,

I used the gravity method. I parked the boat on our loading dock, extended the hose and let the gas flow though a filter into my truck (20 gallons), then the car (10 gallons), then the forklift (5 gallons), then the other forklift (5 more), then finally 2-5 gallon cans.

Several weeks later, we stuffed a gas soaked rag into the fill tube and lit it. Man, I wish I had a video of that event. It gives you an idea what it could do if still installed in the boat, less the shards of fiberglass and battery acid... (Sick, huh?)

Man ... WE could make a movie ...Maybe get LT.DAN in there too ... And the winner of this years DARWIN AWARD..... [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img]

Old gas disposal ...Hmmmm .... Well waste disposal aint cheap ....I was quoted over $200 .... plus a charge for every gallon over 50...they would come to the boat ....but I had to get it out of the tank....

I know someone who has some big farm equipment .... he took it ....Like Otto says gravity ..... But I haven’t blown up the tank yet [img]images/icons/grin.gif[/img]
