Tohatsu 15 HP Efi

Hi guys asking as dont have a clue. Is it possible to disconnect fuel pipe from engine whilst running ? Thinking it would use residual fuel in engine to prevent petrol fumes whilst in storage.Also how long will fuel stay fresh in the fuel line when not in use ? Thanks for any input.

One efi advantage is the fuel system is more of a sealed type than a carb setup. I’m quite keen on fuel stabiliser these days and have been using it for the past year on every tank full.

I’ve heard from several sources recently of even small amounts of water troubling these latest sub 30hp efi outboards so if I returned to using one I’d fit a filter/water sep unit on the.transom.

I use to run mine dry (old habit) have left it full for two years now with no problems as fenlander says the fuel is sealed so will last at least a year and stabilised as an added precaution I too have a fuel separator

What does the Tohatsu instruction book say Dek?

Edit: Didn't realise it would be so easy to find online... I've just looked. Doesn't seem to b any advice other than for "storage" where there are instructions to drain the whole fuel system down on page 71 & 72.

BTW while looking through the manual as far as I read (p.50) you aren't allowed to lay the OB down at all and it has to be transported/carried upright unless drained of fuel and oil... really??

Hi Fenlander the engine can be laid down on the tiller side. There are also square lugs on the cowling to facilitate balance etc.
Nice to hear fuel is okay for a reasonably long period.

>>>the engine can be laid down on the tiller side.

But doesn't the manual say you can lay it on that side *after the oil has been drained* and with a 2"-4" lift at the powerhead end... or am I reading it wrong?

I can read where it says drain down the fuel but not oil?
I does say elevate power unit 2-4 inches if traveling to prevent oil spillage.

I'd like to know if draining the fuel really has to be done as i've not been doing that with mine..

I'm not trying to be a pain just interested really.

The manual I'm reading is from the Tohatsu website...

https://www.tohatsu.co.jp/Portals/0/...EXEU_EN-02.pdf

The page I'm getting the info from is no. 50. The note bottom left.

Geez if I read that page before I purchased a "portable" engine I'd be out the dealers like a shot . Who would buy an engine you cant lie down fully, have to transport standing up and cant trailer in the tilted position?
More to the point why design an engine so fussy for position its almost useless to anyone who uses as a portable
That page is like a "several reasons not to buy this engine" page
