F225: Fuel Pressure, Bogging down,

[tcwave]

Hi,

I have a 2002 F225 with 350hrs on it. I just put it in the water for the first time this season and it idled fine, but then would bogg out and shut off after 15 min at idle. I pumped the fuel bulb and then accelerated to about 2k RPM and after about 2 min it bogged down and shut off. I figured out that if I pumped the fuel bulb ever few minutes, I could keep the engine running.

When I got back to the dock I did the following:

1. Checked (visual inspection)to ensure no water was in the fuel by ensuring the red ring had not risen on my fuel.
2. Visually inspected fuel filter and water seperater and both look fine
3. Check fuses for fuel pump
4. Checked fuel lines, found one connection without a zip tie, so I reinstalled it, but problem continued.
5. Touched fuel pump after running engine for 30 min and fuel pump was hot. (not sure if this means it was running ok or if it just conducted heat from the engine.)

Potential issues to keep in mind:
A. My 110 gallon tank is 1/2 full with last years (Aug) fuel.
B. I had a mechanic install a new water/fuel seperator over the winter. (I think its a Raecor)
C. Engine has never had any issues and has always run great.
D. I spoke with a mechnaic today that recently had to replace a fuel pump in an 2002 f225. (any advice on how to test the fuel pump?)

What do you sugguest? Any and all help would be apprecitated.

Thanks,

2. Check

The mechanical fuel supplies fuel to engine, if pumping bulb keeps it running then may a have bad pump, a resticktion in fuel lines or a air leak in fuel lines.

Thanks, Any advice on how I can rule out / check the fuel pump? It's an expensive part and I can't find any leak or block in the line. I will take off the fuel filter tomorrow to check, but would like to know of any way to test the pump itself.


Thanks,

Also, I was checking out some the threads for this type of issue. Is there both a low pressure and high pressure fuel pump? One of the threads confused me. I know where my fuel pump is, about 4 inches to the right of my fuel filter and is gold in color. Thanks.

use an auxillary tank,DIFFERENT hose and ball hooked to the on-motor filter....to rule out a tankside issue.

Hi,

I have done the following and hope it will work. Tell me what you think.

1. Replaced fuel bulb hand pump on the recommendation of a mechanic that said sometimes they go bad.

2. Replaced some of the fuel tubing around the fuel bulb and water seperator. The area right near the ends of the tube (near the clamp) was splitting. That could have been the cause of air in the system.

3. Took off the fuel filter and it had junk in the bottom of it. It was a brownish slim. I am going to get a new filter tomorrow.

Tomorrow, I will relaunch the boat. Hope all goes well. Any other advice would be appreciated.

FYI...I like your idea about the auxillary tank, but I just don't have one.

Thanks,

Hi,

Problem still exists.

I talked with a mechanic and he recommended I check the connection to my gas tank where there is a small part about 2 inches long that has a ball in it. He thought that would be another low cost item to fix/replace if it was clogged.

Unfortunatly, I have a full tank of fuel which prevented me from taking out the part, however fuel flowed out of it very freely as soon as I removed the connecting gas tubing. I didn't want to get gas in my bilge for obvious reasons, so I immediatly put back the tubing and tightend the clamp.

So now what? Do I assume it's a bad fuel pump and replace it for around $500 just for the part?

I am nervous becuase this may not fix the issue if the internal fuel pump (inside the engine) is bad or the fuel filter that attaches to the internal fuel pump. Any advice on how to determine which fuel pump is bad (external one that attaches to engine or the one in the engine?)

I have also heard to check the fuel tubing connecting the fuel filter to the external fuel pump as it has been known to get a little clogged. I will do this tomorrow and let you know if I find anything. Anyone run into this problem.

Apparently E10 gas that was introduced last year is really screwing up outboards. Anyone else having issues?

Advice would be appreciated.

Thanks,
Ted

I've read of others having ethanol issues.

I'm having some fuel issues as well, but wanted to comment on yours.
If the fuel pump cost $500.00, why not invest $50 in a portable 6 Gallon tank to rule everything else out?

HI, I would like you to try this...In the search box at the bottom of this page, type in "screen in fuel tank", no quotation marks. this sure sound to me that it could be the problem. I see that you have a full tank, so before you start, siphon a few gallons out.
let me know how you make out, Dennis
