Fuel problem maybe? Lack of fuel to the engine? Bad Fuel/water separator?

 

The water seperator is brand new when it went into stoarge last fall. Hmmmmm...

 

Sounds like fuel to me......lack of?

 

Did you put fuel conditioner in your gas tank?
But like Dom. J said I would check fuel supply and filters,
my .02 worth

 

Does the boat have a Fuel shut off valve that you may have closed last fall & not opened this spring? Just a thought.....

 

Yeah, she got the full treatement of Stabil. Could it have been just the fact that it was the first (and then second) time it had been started this year?

Sounds like a no on the water. I think I better try and run her again and throttle it a touch, see if it just needs to be run, free it up a little.

 

And I have no idea where the shut off is, or if it has one.

 

If you changed the water seperating fuel filter last fall & did not fill it with gas before putting the new one on.... the I'd guess you have your answer... Throttle it when your start it.... takes a while to fill that filter....

 

Well with my hose on full blast, when I start the motor all of the water is being drawn into the drive, no extra spray like I used to get with the small block. After about 10 second the boat quit????

Check the oil for water.

If you see water in the oil, pull a plug and see if water is in cylinders.

Did you have boat on level fround or at an angle? If at an angle was the stern up and the bow down?

 

Is your boat F.I.? I believe (but could be wrong) you have to fill the fuel filter full of gas before reinstalling.

 

Speter2405 - you are probably on to something. This happened recently to someone here. I read the first time on muffs thing and on full blast, so I automatically said to myself "Uh, oh!"

I am behind the fuel water separator idea.
I have been there.

 

This makes me feel much better! I think I'll light the fire again tonight when I get home and let it run, hoping it will. I just didn't want to start it again yesterday thinking it was my garden hose pressure that was causing my problem. I think I'll start it, goose it a touch, and see if she'll idle for longer then 20 seconds. Here's to hoping....

Thanks for the input, guys.

 

This may or not be a contributer to your problem. But I've heard that gas can go to chitt after sitting for a few months. Even if you put stabilizer in it. Again, just what I've heard.

There was about 20 gallons in my tank when I put the boat up for the winter. I did add stabelizer to it. But I'm going to syphone it into 5 gallon cans and use it for the lawn mowers or whatever. Then put fresh stuff in before the 1st start of the season.

Good luck. Hope there's nothing serious going on.

 

gas can go sour after some time, but not necessarily over the winter unless it was bad to start with. This is the classic symptom of not putting fuel in the fuel filter before re-installing.

 

Yep the empty fuel filter is defintely the problem. If you have electric fuel pump on the 454 you can turn the switch on and off several times (10 or so) to help fill the filter first. But give it some throttle while cranking and that should help as well, don't worry you can't flood the motor cause it's not getting fuel.

 

I'm surprised that no one has suggested to check and see if it has spark.

Has to have spark to run, boat runs for 20 seconds, I place my money on the water'fuel seperator.

 

Mine done that at first but one of my batteries was about dead so I give it little throttle for a while and it cleared up. Once I let mine run for about 10 min all was ok. If you dont have enough power from alt or batt is dead your efi wont work right. Thats what it seemed to be in my case.
