ok to use this kind of filter for my 6hp tohatsu http://www.ebay.com/itm/K-N-Inline-...Parts_Accessories&hash=item19d9b02c1a&vxp=mtr ?

I talked to someone at a boat part store, he suggests that there's nothing particular about marine filter.

that would be a minimum, but a water separator / filter with a visible bowl is recommended.

This is the unit recommended by Tohatsu.

wow, no kidding, at $87 at pop. it'd probably makes more senses to buy 12 of those from ebay and change it once a month than buying one at $87 that only tells me it's time to change it.

the BIG difference between them is that this is a water separator and a 10 micron filter, where the one you found is really just a fuel strainer. It won't stop water or small particles.

Anything much smaller than a grain of sand will probably pass right through that filter and still be plenty large to clog the carburetor, where this filter would stop anything even remotely large enough to clog the carburetor, as well as any water that makes it into the fuel system.

Simple outboard motor in line pre-filter setup

Simple outboard motor setup.......I have a 20 + year old 8hp Nissan. I use an inline pre-filter Just after the squeeze bulb. It looks like the one pictured below. Always use fresh fuel so no need to worry about water in fuel. I use a 3 gallon or 6 gallon tank depending on my need at the time. I believe I bought it from wally-mart and the packaging was label attwood at the time. At least thats what I can remember after 20 years of use. It has been thru about 3 sets of portable fuel line hoses or new squeeze bulbs. Never have needed to change filter under engine cowl. Nissan runs like "BANSHEE".
The filtering on the inboard diesel yanmar or kubuda generator gets a little more complicated.
But for your outboard motor, your needs are not that complicated and can be much simpler....So just use the K.I.S.S. principle.

FP, thanks for the link. May be overkill but getting stuck on the open bay, in the heat, no wind and no motor will likely turn the Admiral into an Ex Admiral. I'll spend the $87 for a good filter.

That is the EXACT same logic I used to decide to order it. I am switching from a 3 gal portable tank to a 9.2 gal below deck permanent tank this year, and won't be able to easily insect the inside of the tank anymore for sediment. My engine has never failed to start yet, and that single fact probably is why I get as much leeway with her as I do. An engine failure at the wrong time, and I'll be a solo sailor for life.

i always used the old 1-4 dollar filters and i never had to rebuild my carb, while everyone else was doing that weekly .... worked well for years. i row now-dont need filters for that activity....

If you have an inboard fuel tank with many gallons of fuel, gas or diesel sitting for long periods then an expensive filtering and water separation system is going to be nesassery .
If just a simple out board motor using a 3 or 6 gallon portable tank were old gas does not have to sit stored for long periods . And only fresh gas is used as needed. Then the k.I.s.s. Principle will do just fine. And should not leave you stranded . Go back to his original inquiry. Simple outboard Simple portable outboard gas tank.

Regardless what you have, or use downstream, one of these, or something similar, should be your first line of defense. Its seems crude, using something that was common over 50 years ago, but the simple truth is they work, and work very well. Its often not the particles that get past the filter that clog the carb, its the gum and varnish. Even the smallest particles can be captured by the varnish and gum deposits inside the carb and build up until you have a problem. Also, being able to clearly see water in the bowl, and being able to simply remove the bowl and clean it (and the brass screen) and be on your way, makes the problem less of a big deal.

If you use ethanol

If you use ethanol I would suggest a water seperator. I recently went through hell, getting the water out of everything. No more ethanol for me. I just use an autmotive inline filter. Actually I use two of them. One right behind the squeeze bulb, and on the engine itself. But once again, if you are using ethanol, thats a different ballgame.
