the Briggs and Stratton additive is definitely good, though other companies make similar stuff. I have about 6 two strokes and it does make starting easier and helps prevent the corrosion of gaskets and fuel lines - though I now use premium petrol, as well.
 
DIy alternative, siphon the petrol through an inline filter.
In fact, why not fit one to the outboard?

The fuel filter taken off a petrol fuel injection car or motorbike at servicing time can be used to filter dirty petrol.
 
If it wasn't for the price, I'd buy one just to see what mechanism is in there to separate the water from diesel.

A bit like the water trap on a Landrover perhaps?
 
I have one. The fuel floats on the water. The funnel has a small coffer dam in it and the water stays below the coffer dam, while the fuel enters over the top. There's also a particle filter above the cofferdam.

I found it very useful when I got a batch of salt water contaminated diesel. I decanted the contents of my fuel tank into a couple of jerry cans, stopping as soon as I found evidence of salt water in the fuel. The rest of the tank contents were dumped into a waste oil container. I then ran the diesel through this filter into another clean jerry can, dumping any water into the waste oil. I repeated this a couple of times, cleaned the tank and after doping the fuel with emulsifier and biocide, put it back in the tank. It worked for me.

Thanks for that.

Good product to have.
 
Any where your fuel supply is in any way suspect especially if it comes from 45 gallon oil drums half way down the Baja or in the far out islands in the Bahamas a wise man filters any fuel as it enters his tank. I have one of these

It keeps dirt and water out.

On this side of the pond it is called a Baja filter.

The stuff sold to add to a tank containing small amounts of water actually works much to my surprize.

Which reminds me we are due to get several inches of rain from this tropical storm so I need to shut the air bleed on the tank for my outboard.
 
It's probably a coincidence, but I recently found a can of 2stroke mix of uncertain age. Reluctant to use it in the outboard, I originally intended to sling it in the Morris Minor next time I filled up. This week, doing a bit of gardening, I ran out of fuel for my strimmer. I used the filter when filling it up from the old mixture can and apart from a lot of smoke, it ran perfectly. The fuel was at least two years old, if not more.
 
I have the smallest Mr Funnel and use it regularly to good effect. The fuel tank on our boat is smaller than usual, so we have about 100 litres in cans. We tend to top up the tank from the cans and only fill the tank directly from time to time.

I tested the filter when it was new by simply adding some water to a bottle of contaminated diesel and it worked well. As far as I can remember the filter mesh is made from (or coated with) a hydrophobic material. The bulk of water falls into the trap at the base of the filter. Particulates and water globules roll down the filter and fall into the trap.

The level in the trap will obviously rise above the filter at some point if you continue adding water. Even a small head of water will overcome the relatively weak effect of the hydrophobic filter. So it's important to empty out water if the filter sump begins to fill. This would only be an issue with large quantities of heavily contaminated fuel.

N.B. My Mr Filter is yellow and doesn't look much like the eBay picture. Fairly similar to picture of "Baja filter" though. Perhaps it was taken from a bad angle and doesn't show the actual filter part.

I have one of those and it's not practical to use when filling up from a fuel barge - too slow but useful for filling from a jerrycan. It always leaves a few centimetres depth of fuel in the funnel - what is one supposed to do with that!

No experience of the fuel filter, however, based on advice taken from this forum I purchased the B&S fuel stabiliser for my garden equipment. It works well, my perception is that the equipment runs smoother and the chain saw starts easier, lawnmower has always been a good starter but made a 'burbling' sound once in a while, that has stopped since the Fuel Fit was used. I recommend it.
 
I remember as a boy seeing my father filtering petrol. He used the crown of an old felt trilby hat. I do the same when using a funnel when refuelling. If there is any grit the felt stops it from getting into the tank.

H&S warning. After filtering using this method do not put the hat back on your head and light a fag!

You run the first couple of gallons through the filter into a clear plastic jerry. If that looks clear then carry on filling the main tank.

Use any contaminated diesel as a fire starter. DO NOT USE CONTAMINATED PETROL AS A FIRE STARTER. SEE WHY BELOW I am sure that you already know why

 
Quite impressed with funnel. Seems to do what it says. The method of testing whether the funnel is still functioning as it should is to put some water in the bowl, which stays there. Having emptied the water, fuel passes through quickly. I am only using it to fill small fuel carriers and outboards etc. If I had a boat that was filled at docks I would consider one of the bigger ones if the flow rate was suitable.
