Cannot find gas line filter

[iggyw1]

Hi again guys. Some of you may recognize me from a post on the Mercury motor section. I first posted in that section thinking I have a Merc motor when it is indeed an Evinrude. I am having a little problem with it stalling out when trolling (very slow idle only) where I have to pull the choke out slightly closing it about 25% or even less to keep it running. I got the advice to clean the carb which I will do, but now I have a second question and posted it correctly in this section.

My motor is a 1991 (not '86 like I last reported) Evinrude, model # E6REIA. (Found all of this out when I got my manual out from the garage today). In the service manual that I have, it shows a fuel pump filter and how to clean it, which I did last fall. It also shows a fuel line filter and how to clean it. I cannot find this fuel line filter on my motor. When I bought the motor just last year, I bought it from a fiend that I worked with for 30 years and we retired together in 1999. He told me last year when I bought it, the motor had only about 10 hrs. on it, which I truly believe. It now has about 50 hours on it since I used it to troll with last year. Ran perfect except the last couple of hours, wanting to stall out while trolling unless I slightly close the choke like I sated above. I know that my friend did not remove the existing gas line filter, and nobody else did. Maybe it never had one even though it shows in the service manual??

Can I add an inline gas filter outside the motor on the gas line going into the motor with no ill effects on the motor? Does anyone know if any of these motors were built not containing a gas line filter that is indicated in the manual? Thanks for any ideas you may have on this.

If you can't find it, then there probably isn't one, you can add one if you want. And the fix is the same for either brand, clean the carb.

Since you are doing slow trolling, you might check the spark plugs for fouling in addition to the carb cleaning. Plugs can load up with carbon if you don't run it some at higher speeds to burn it off.

One other thing - If the filter is the problem, adding one more won't fix a downstream plugged filter. Going by the model number E6REIA, the filter screen is on the inlet to the fuel pump. Item #3 in the diagram below, Good luck.

ondarvr, Thanks. I figured the advice on cleaning the carb would be the same for any motor. I do plan on doing this.

GA Boater, Thanks for the advice. I did run the 6 h.p. motor wide open on my 16 foot boat trying to burn off any carbon build up on the plug. I was thinking for the cost of two plugs, I am going to get two new ones this season for sure. Even if I cannot still get the plug listed in the specs, there should be a cross-reference chart for the new plugs I would think, right?

I see the diagram you posted in my service manual. I did clean that fuel pump screen last fall (it looked brand new when I removed it before cleaning). It really did not help the situation because it was clean. . However, there is also a " GAS LINE" filter too shown in the manual (besides the fuel pump filter) that I cannot find on the motor. I realize that adding an additional gas line filter (in line) won't help a downstream filter, but I certainly do not see the filter that is suppose to be there on the gas line. Hence my question, if some of these motors were made without this gas line filter? (not the fuel pump filter). I do not want to multiply the problem by just adding a second gas line filter if there is one underneath the motor head where I cannot see it, but I don't think they would be that stupid to put a filter way underneath something, would they?? LOL I hope not, but you never know. My motor was made in Belgium.

edit: Just a new thought. MAYBE my service manual should have stated that "IF" there is a gas line filter on your motor, this is where you would find it, and this is how you clean it. Instead, they make it sound, in the manual, that ALL of my model motor has this in line gas filter as well as the fuel pump filter.

The plug listed in the parts catalog is L77jc4 (#821m) and is readily available. As far as xref goes b7hs-10

 

[GA_Boater]

The inline filter may not be used in all years or models of the motor. No idea. An "IF" would be nice.

I looked through all the fuel system parts diagrams and saw no filter other than the fuel pump screen. Some filters don't look like filters, which adds to the confusion. Try tracing the fuel lines, You might find the filter in the cellar. LOL

Thanks for that info. I was hopeful the plug would still be available. Probably should have replaced the spark plugs the day I bought the motor.

I looked and looked for that gas line filter that they are showing in the service manual. (if I knew how to post anything other than what I can type, I would show you a picture of what is in my book) LOL No such thing exists on my motor I determined. I am going to install an in line gas filter on the outside of the motor, although, I do not know if it will be better than the fine screen filter that is there now in the fuel pump housing as shown in your diagram. Can't hurt I suppose to have the "extra" filter in line. I kept calling the book I have a service manual. I think it is actually the owner's manual that came with the motor. It is not a full service manual that I have. Thanks again for all of your help. I really appreciate it.

iggyw1, the screen filter in the fuel pump really isn't a fine screen type. It is quite large as fuel filters goes. If you are getting issues with dirty fuel, install a filter in the fuel line. But I don't think that will cure your slow speed issues myself. If you can drain the tank and clean everything out of it, that should go a long ways to stopping dirty fuel problems. If you are needing to choke the carb to keep it running, sounds like you need to either change spark plugs to a different heat range or adjust the carb,'s low speed adjustment after a thorough cleaning, or do both. JMHO!

It ran great for most of the year last year when I bought it, then all of a sudden it started up that stalling was quite frequent unless I pulled the choke out a bit while trolling which that way it is running too rich and I know I am fauling the plugs up with carbon now. Near the end of the season last fall before I winterized the boat ( in Mich.) I put some sea foam in the gas and ran it a bit too hoping that would clean up the carb. Will run the remainder of that gas through the motor real quick this season then put some fresh new premium gas in the tank with some sea foam.

 

[ondarvr]

Premium fuel isn't going to help anything, so save your money. There is a very remote chance Seafoam will help, it normally comes down to cleaning the carb, it's very easy to do. One thing that works every now and then, is to turn the low speed jet all the way in, then way out, then back to where it should be. If there is anything stuck near the needle it may pass through.

^^agree.

Might have missed this in your narrative, but think you might have a fuel pump issue -- torn diaphragm is most common (or holes), but I've had a couple that were just old (took a set, lost elasticity -- almost like cardboard.) Think you might be due for a rebuild kit, or replace the thing. If the pump is weak, you might help it out a little by setting the idle stop to keep idle speed up just a little higher, but that would be just a patch.
