Fuel connections

[lightflyer1]

In my younger days outboards I remember had removable fuel connections on the engine and/or tank. Currently mine are fixed in place and not removable. Can this be converted to the kind you can at least remove to run the fuel out when done with the boat for the day? 2002 Mercury 25hp pull start.

just search for inline fuel couplings..connectors..might get a shutoff also..ebay is full of them..

Fixed on the motor itself ?? Never saw that, on some of the cheap plastic tanks the hose is clamped on , but haven't saw that on an outboard.....

Usually any "portable" outboard has a fitting on it. Did you buy pre-owned?

I’m not sure when Merc went to EFI on the 25hp. Anyway, if EFI it’s not a good idea to run the fuel out.

I didn't know that; thanks.

I have a 20 HP Merc EFI. SO I went and looked it up in the maintenance manual. Sho 'nuff, it says to add stabilizer to the fuel and run it to make sure the fuel system is full of stablized fuel before storage. No words about emptying the fuel out of the system EXCEPT for fuel with ethanol in it. In that case, they instruct to empty as much of that ethanol fuel as possible and then prep it for storage with stabilized non-ethanol fuel.

I have been running the system out of fuel before storing for the winter. No more.

Learn sumpin' new every day. Thanks!

I have a 25 Merc EFI. I think it's a Tohatsu underneath. Really big motor for 25HP.

Mine has a fuel connector, though. Someone must have bypassed it in your case.

Some come with the fuel connector on the end of a short fuel line. Maybe that is how yours was originally?

I won’t run ethanol fuel in an outboard or any small engine for that matter but, that’s another story.

I just stabilize my E fuel and go to sleep, never had a problem since it came to market. The key is " stabilize" your fuel.

I was thinking exactly the same thing. Seems odd.
