Re: E140txcdc..

The valve on your primer solenoid could be bad, allowing fuel to keep running into the engine and flooding it. Try closing off the fuel supply to the primer solenoid and see if it changes anything.

Are you getting more smoke than normal when the engine does run?

Re: E140txcdc..

the primer solenoid has the red lever... going straight up and down... will turning the red lever accomplish the shut off or do i need to clamp the hose shut??...I dont see any shut off in line per say..

Re: E140txcdc..

No, there is no shut off. You would need to disconnect the line and plug it temporarily. Be careful not to break the nipple.

Re: E140txcdc..

so i went out and looked at plugging the line...there is about all of 4 inches of line coming from the solenoid to the T connection where the feul distributes into the four hoses...


help understand this..I look at the solenoid..and only see one connection to it (my eyes may be bad). Am i to plug the hose that runs to the T??

Thanks!

Re: E140txcdc..

another thing... when i removed spark plugs they did look a tad wet..would that be indicative of flooding?

Re: E140txcdc..

sorry missed your smoke question... and yes i think it is more than it should be

once she settles in a bit it gets better as things burn off...but then she cuts out.. upon restart a whole bunch of smoke again..

Re: E140txcdc..

The primer solenoid has one line going in and two small lines out. the two going out are then spllt again so that one serves cylinder one and two and the other serves three and four. You could clamp the hose shut I guess, but you may have to replace it if it breaks.

The fuel pump supplies fuel to a fuel manifold which then serves the carburetors and the primer solenoid. The fuel mainifold has five outgoing lines.

The one line from the fuel manifold to the primer solenoid is the supply line which feeds the pressurized fuel to the valve.

Re: E140txcdc..

Sometimes the extra smoke will indicate an air leak in the gasoline side of the fuel system, which in turn will cause the VRO to pump more oil than needed, plus make the engine run poorly.

Keep a little pressure on the primer bulb and carefully inspect all of the hoses and connections. If fuel can get out, air can and will get in.

Re: E140txcdc..

so which line should be pinched or plugged then?

The two lines going out of the solenoid?.. or the larger one that feeds off the manifold?

the lines are not hard...or rotted in any way. I did spot check for feul leaks and didn not see any wet connections. Ill doublecheck when i get back outside.

whats strange to me is that I had my boat mechanic here 3 weeks ago and all was in order..she ran, long and strong.. today I have this issue..or yesterday rather... between bad weather and work i did not get a change to water test after my mechanic had been here..

Re: E140txcdc..

all things being equal I should be able to clamp shut the line from the manifold going to the solenoid??

No.

Re: E140txcdc..

Thanks for the input..I'm giving up on this ..been at it since 10am

I did what you suggested..clamped the line...she started up and after a minute she cut out just as before..

I'm baffled... I have good compression, fuel, water seprator, new plugs...

I did notice one drip..and i will fix that but it was tiny..

When running i reved up a little..noticed some mist came out of one of the carbs..I assume fuel

I imagine that alone is not my problem...something is cutting me out...but what?...agghhhh!

I'll sit and ponder for a bit.. i'm going to get my neighbor to help me check spark...after that..I'm lost..

The mist could be because of a bad reed. You would have to pull the carburetor to really see it.

Re: E140txcdc..

Now I am more confused...

my friedn who is a car mechanis just cam by with an inline spark tester..

Initially it took a feww revolutions to start the spark charging..needless to say..with the inline spark testerin place she fired up and this time stayed running!!!!!!!!

I'm even more confused now... The only thin i can think of is that my battery was getting low and after all the work i was doing was below spark capabilites to turn the engine at the required 300 rpms...to the ye it looked like plenty of turning..

My plan in the morning is to charge the batteries..and give it a go again and see if spark generation is quicker..and if she stays running

Why it worked when he was here is still a mytery but maybe letting the batteries sit for a bit helped?..

Ill update tomorrow with new findings...in the mean time any suggestions would be appreciated..

Thanks

Re: E140txcdc..

UPDATE:

This morning i went out and charged my batteries. I then started the engine and it immdiately started and kept running...this time didnt cut out. kept it running for a good 5 minutes.. I then shut her off. waited about 5 minutes and started again.. no problems..she fired right up, i let her run for another 5 minutes..all seems great now.

So my question is this.

Electrical:
Would a weak battery cause the cutting off from before? I assumed once she kicked flywheel magnets charged the coils packs and away we go....

I also looked at the battrey guage..she stayed around 12 volts. On my last boat, when the engine was on she stayed at 13-14..assumed charging.

Do outboards charge the batteries as inborads do?? Is there a power increase seen on the guage?

GAS:
When running for a bit I noticed a milky residue on the lower two carb , the top two showed nothing..Any idea what that my be? I figured foaming or something but when I wiped it it felt like white grease per say..not as thick but had that coloring.. again on the two bottom carbs..

Appreciate all the help..i am learning a bunch.

Happy Fathers day!

Re: E140txcdc..

the engine will charge the batteries however it will do it very slowly especially if you have deep cells. your stator only puts out somewhere around 6-10 amps and thats at wot. at idle it's only about 2 amps. if your running with lights on, vhf, radio and fishfinder your probably draining more from the battery then your charging.
in my experiences stators do put out a slightly lower voltage then alternators but you still should have at least 12.5 volts. shut off all your accessories and make sure your batteries are fully charged. if you can take them to autozone or pep boys and have the batteries load tested. it's free and it's a much better check then the meter on a charger. just dont buy batteries at either one. i've had really bad experiences with autozone marine batteries and i believe pep boys uses the same manufacturer.

Re: E140txcdc..

Thanks BP... I will definitely do that. I also wonder of charging the batteries while still on the boat is ok or the best way to charge...

I usually dont pull the batteries till the winter..

Any suggestions or input on the milky resdidue I saw in the carbs??..I posted a new thread for it but if you have any input then fire away!!

Thanks

Re: E140txcdc..

By definition an alternator is a generator that produces alternating current, which is what you have. The rectifier uses a system of blocking diodes to convert the alternating current into direct current for charging the battery.

A battery is not necessary for the engine to run. It can start and run with a rope if you are strong enough.

Re: E140txcdc..

I guess my phantom problem is still a problem then...

As mentioned in previous posts..she had started..and afetr a minute cut out,,

The last time, after charging batteres full, she stareted and stayed running strong...

I can only think she wasnt cranking fast enough before..but the fact that it caught and ran...and then stopped,, tells me I may still have a ghost in there.

Maybe between the feul and battery being low..??? odd really...

Guess ill take her out for a spin...close to shore... and run it hard to see what develops..

Thanks for the help! I'll update shortly!
