Engine stalling problem

CL 240 LS · 08-07-2009, 06:29 AM

Hi Bigdog
I reread the thread on gas tank, http://www.winnipesaukee.com/forums/...ead.php?t=7494

You said you drained most of the gas but the bottom 5 gallons remained. Are you sure there is no debris in there? Did you located and check the pickup tube and was there a screen on it? Maybe worth looking at again no matter how big of a pain.

Hi again....

I will respond to each of the recent Posts in order:

Airwaves
Alternative fuel source test, have not done yet. May be the next test I'll perform this w/e when I arrive in Meredith for vacation. Certainly would prove
conclusively if this is fuel related, and rule out ignition issue.

Acres per Second
Have not changed the fuel line. The diaphram in the fuel pump cannot be repaired, it is a sealed unit. I think they make it that way so you have to buy new !

CL 240 LS
I personally did not check the pickup tube, but my marine tech, recently removed checked the Anti-Siphon valve, which he said was working perfectly fine, and the ball inside ASV was moving freely in the fitting as it should.
BTW, what is 'CL 240 LS' a Crownline ? If so you're one lucky guy !

That I am!

Hope you get up and running soon. Try finding a portable tank and hooking it up to eliminate as much of the fuel line components as possible. Maybe a local marina has such a setup that they can try?

OK, I have to share this with you folks, because it is almost unbelievable.

First off, I "think" "hope" that my stalling problem is fixed. We went to fireworks in Alton Bay Saturday Night, went to Weirs Beach Sunday, and went to Center Harbor, and then to Meredith for Dinner Yesterday, without a problem ! ! So, bigdog, assuming I am fixed, it was the ASV, Coil, Fuel Line from Tank to Engine, or Vent Line.

Now for the story....

When going to fuel up yesterday, I want to pour my StarTron into the tank. Did not realize the the little Plastic/Paper Seal thing under the cap was stuck on the top of the bottle. As I tipped the bottle to pour it into the tank, you guessed it, the little disc went happily into the fill hole!!! What are the chances ? So, I went over (I was at West Alton Marina) to the mechanic and talked with him. He told me, you have to get it out because it could plug up your intake and ....make the boat stall.....

So, we have an appointment tomorrow morning and he is going to try to fish it out of the tank through the sending unit acccess hole.

Just wanted to share what I hope is the fix, and the simply unbelievable story.

I had the same problem with a Mercruiser 3.7. After a mechanic changed the points, rotor, condenser and coil it ran in the driveway (with earmuffs) but stalled out when I accelerated on the lake. Next I changed the fuel filter and dumped the contents into a clear container and it was 90% water. So I drained the tank thru the hose attached to the fuel pick-up and there was some water but not as much as I expected. I also found that the hose from the fuel pump to the fuel filter had a kink in it that may have restricted fuel flow so I replaced it. I know that there could be a small amount of water in the bottom of the tank that the pick-up did not reach so I poured in two bottles of drygas and 1 bottle of Seafoam and then added 10 gals of fresh gas.

It started in 2 seconds and ran well on the lake at varying speeds from idle to 4000 RPM for the first hour and then I took a prospective buyer out for a second hour: still no problems. Hurray!

The buyer trailered it to his lake last Sunday and added about 15 gals of fresh gas along the way.

The buyer called me on Monday to tell me that he had been out for about 3 hours the engine ran well but he was now in the middle of his lake and the engine had stalled and would not start.

Although it was an as-is sale I feel badly about it. It does not seem that he would be out of gas-- combined we put in 25 gals and ran the boat 2 hrs here and 3 hrs there. Is this engine that thirsty?

If anyone has any suggestions they would be greatly appreciated.

It is starting to sound as if you had better join the famous clunker reward program with a boat.

Big Dog,

As it is appearent you have been having the work done to your boat.... may I suggest Goodhue Marine in Moultonboro.... I have been using Brett and the boys for several years..... If you are having an issue with fuel getting to the carborator they will figure out why.....

OK Bigdog, what are the results? Did it run all week? What did you replace?

It's been almost 2 weeks since Bigdog gave us any input. Maybe the boat is up on a trailer for the rest of the season.
