like most boats my 21w/a 150 ever. has a out side replacement fuel filter. w/ petcock on bottom of glass bowl, to discarge water in fuel... my question is would 2 filters work better than one??????i,m afraid of the gas we get today w/ ethanol

word has it two will restrict the gas flow to much..as in motor starving for gas.

Not if you use two but not in series. (one after another), split the fuel line with a Y fitting, go to each filter separately then bring them together again with another Y before the engine (thats putting them in parallel). I was thinking of doing this if I decide to use 2 filters.

It's not how many filters you have in line or splitting the line to seperate filters.
10 micron or more is more important.
Most racor filters (the ones with the clear drain bowl) are 10 micron

YUP all the ones I see now are 10 micron.
Very important
However, some engines can be fuel starved using just one 10u filter.

I have two filters and it dosen't restict any flow. Mercs have a filter in the engine, and this season I decided to add another due to the e-10(racor). I can't see any fuel flow issues from last year to this year.

no problems on any of the boats i fish with the new gas.
just keep burning up the fuel.
i think most of the problems come with letting it sit.

mike.... i,m done 4 the yr. got a full tank of gas.. what should i do w/ fuel tn tank????.... i guess change fuel filter every 50 hrs or less......

empty the tank !

my thoughts exactly....van
and it would be nice to be able to isolate a clogged filter from the Y
for non stop running or the cleaning of it... :btu:

stiffy run the gas out then put some stabil in the tank..

YUP !!!

I came into my slip on fumes yesterday...:shocked: :shocked:

Codwishing anyone in Boston Harbor in November/December? Run it dry.

my buds wellcraft HAS to be full all winter. the marina won't give you winter storage if the tank ain't full. we had a fire last winter and none of the boats blew up 'cause they were full.{this is what they tell me}
the bossman there says just filler up and forget it. full tank= no room for condensation. maybe some octane boost in the summer??:huh:

I have talked to 3 different marine mechanics, and got different answers. My friends mechanic was putting all the boats away with full fuel. The marina where I keep my boat in the summer was putting away boats fullas well, they both recommended fuel stabilzer and water absorber.

The Yamaha Dealer who rebuilt my engine this year, who is winterzing the boat said they always put the boats away empty or darn close, with fuel stabilzer and water absorber.

So I went with empty, his reasoning was if the new gas seperates over the winter is is a lot cheaper and easier to get rid of 20 to 40 gallaons than 160 gallons of bad gas. Also he recommends going up 1 level of ocatne for the first tank of gas in the spring to make up for any octane loss.

Now it is a wait an see what happens in the spring, to see who's advise was better.

just keep burning up the fuel.

Mike, I think that goes for where you get your gas also....all year I have used gas cans..fresh gas from the street....NO problems at all.
my last fill up was at one of the docks in the town river....now I'm starting to see the motor running rougher and harder starting...the filters are new the one on the motor and my racor fuel/water separator....

Time will tell with new fresh fuel this weekend........not from the fuel docks......:devil2:

This is what the fuel in my fuel filter looked like.....

i have keep mine full with stabilzer i put the stabilzer in on the last trip out to get it in the lines and carb

We have had the ethanol fuel in CT for a couple years now. Last year I left about 20 gallons of fuel in my 100 gallon tank, and mixed in the stabilizer.

In the spring the boat ran fine (I added about 10 gallons of fresh fuel to it). I will say that you need to drain all gas out of the carbs. If you don't, the gas will evaporate and leave behind a powdery crud that WILL clog your jets when the boat is run in the spring. It took me two seasons to figure out that part.

I have the racor filter with the glass bowl. Leaving the tank 80% empty has not yielded any water in the racor yet. I do nothing to the vent. The boat is covered in a dark tarp, so it does heat up like a greenhouse on sunny days and cool down overnight. Not sure why I am not getting a water problem.

Striper1 not sure what it is worth but when I changed mine last month it looked exactly like yours. I haven't had any problems yet, I just use the mfg omc filter nothing special and the fuel dosen't sit in my tanks very long before being used up.
