Outboard engine w/integrated fuel tank?

I've googled this one and haven't been able to find anything...

...does anyone know of a small outboard engine with an integrated fuel tank (like on a lawnmower, but with more capacity maybe)?

Alternatively, after-market or DIY ideas for bolting something on to an old merc 4.5 would be much appreciated.

I've got a big old steel tank that I think is overkill for getting in and out of the marina, and it takes up a lot of room in the cockpit of my Catalina 22. I'd also have to worry about venting if I go the route of getting it (or something smaller) out of the cockpit and into one of the lazerettes.

Information, ideas, comments?

I not sure I understand all you ask.
There are some small outboards that have a fuel tank built in.

If, a person enjoy Nostalgia there some very old ones that are larger H.P. the have tanks.

DIY this made me think of an old outboard I see at around boat dealers on display. They have a round tank mounted with metal straps. It not hard to do just requires some thought as to where you mount the tank, fuel flow/routing and maybe some rubber bumpers so there not wear on metal from vibration.

If, I find a picture I will show you.
This link an old motor, we not worried about that, but, see the fuel tank?

This not the best picture and would help to see from a few angles. Maybe it will help.

The fuel line not need a pump ball to prime as the fuel flows by Gravity to the carburetor.

Argh - thanks folks. I was googling the wrong term (integrated as opposed to integral).

Live and learn. Much appreciated, as always.

Most of the smaller outboards, from almost all the manufacturers, have an integral tank. However, depending on the size of the engine the tanks will differ in size. On my Tohatsu 3.5HP four-stroke it is about .3 gallons...not a gallon as you indicate.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Yamaha 4 hp 4 stroke has an intefral tank, with option to connect external. I seem to recollect about an hour's drive time with the fuel in the tank.

As USCGRET1990 says, replace your steel tank with a small jerry can from West Marine. They have all the adapters you will need.

I have several jerry cans on my boat. I haven't gotten around to cleaning the built in tank. One nice thing about the jerry cans is that if I get a tank of bad gas from some marina, it is isolated to that jerry can, and has not contaminated my entire fuel supply. Also, you can fill the jerry can at a regular gas station. Tough to do that with a built-in tank.

Merry Xmas,

I've got a 2006 Johnson 2.5hp 2-stroke with an integrated tank for sale right now near Albany NY... used for one season in fresh water... I just wanted something bigger. PM if you're interested Did I just completely violate the Sailnet rules?
