Default 07 Suzuki 225 dies on startup :-(

Howdy everyone,

looking for some quick insight here if possible. Went out on the water today to the sandbar and motor ran great the entire way. Went to leave the sandbar and the motor ran for about 5 minutes then sputtered off and died. Now it wonít even run for more than 15 seconds without stalling and dying. Tried to like the fuel bulb but itís not getting hard.

Not sure if this is a coincidence, but on the way to the sandbar the oil light started flashing, but google tells me thatís just an oil change reminder.

Some other quick notes:
- I only use ethanol free and donít let it sit in the tank very long. I usually only fill up with what Iím going to use for the weekend
- I filled up with gas this morning
- I just had my trim and tilt motor unit and they pulled off the OB in order to replace it

Hoping this is something easy and cheap to fix as the trim and tilt assembly cost me a real pretty penny a few weeks ago. Thanks!

Sounds like bad fuel, less likely the AIC acting up.

If it is an 07 engine it could easily be the AIC as that is the era when that problem occurred. Removing and cleaning it usually solves the issue.

No worries! It did feel a lot like I ran out of gas, except I put 25 gallons in earlier this morning and only went about 10 miles at most.

Id say air in the fuel line. Maybe a crack in the rubber fuel line somewhere between tank and motor. Do you have a water seperator? Make sure filter didnt rattle loose and break the seal.

take it to Suzuki and get a diagnostic report .

messing around with these motors blind is futile when it comes to diagnostics.

you can get a kit on flea bay and set that up on a lap top for cheap to name

a few things to inspect if you want;

.check FPR for cracked or broken hoses ,sounds like from your description a fuel pressure leak or maybe air lock, clogged filter, etc.

check the oil and make sure it is oil and not fuel , these motors have a air bleed for the VST that goes into the motor , it can bleed fuel into the oil if the NS in the VST gets vapor locked.

as posted , get diagnostic done before messing with shit.

Possibly got a dirty load of fuel.

If you have a inline fuel filter/water separator (you do have one, right?) change the element.

We had a 60 doing a similar thing, ran 100 yards then stopped and wouldn’t restart, couldn’t get the primer bulb to pump up.

A new filter element and the problem solved. Even if its not the solution, at least you know and a filter element is not expensive.

1 check your fuel filters
2 vent the vst tank / test
3 buy amazon iac valve cheapo and see if that helps.

Hey everyone, wanted to report back on this. Once I got it home on the trailer that day, the primer bulb got hard after a couple of squeezes and it ran fine. The next day it went into the mechanic for its 200 hour service and the fuel filter and fuel water separator were replaced along with everything else. I asked about my IAC and they tested it, said it was a little slow to respond, but was working fine and passed all tests.

The issue seemed to be gone except it happened again last weekend.

I was probably running a little closer to E than I should have been, but we were about 5 minutes from the dock on our way back from a 30 minute 30 MPH cruise back from the sandbar. About 5 minutes into getting into a no wake zone, engine sputters, stalls out, dies, and then stalls out and dies on restart. We got towed to a gas station, put 30 gals in, but the boat still wouldn't start and again the primer bulb wouldn't get hard.

We ended up getting towed back to the ramp. Got the boat on the trailer and drove home. Once in the driveway, the primer bulb primed fine and the motor ran fine. Took it to a lake the next morning to let it run for 10ish minutes and it did fine.

Knowing all this, it seems like there's either air in the line or gunk in the tank blocking the line, causing the bulb not to prime, right?

Any ideas?

Thanks

While that's quite a possibility for what happened this last time, the first time this happened I had just put in around 30 gallons and only used about 10-15 at most the same day. Unless the first time was caused by a filter being clogged and this time was actually caused by running out of fuel and it's just a coincidence.

How long were you at the sandbar the first time it happened?

Probably 2-3 hours at most.

How old is the primer bulb? There are only a couple reasons why the bulb won't get firm. Either it's worn out or you have a blockage somewhere upstream.

If you can duplicate the issue again, I would immediately check for spark. Is the engine throwing any codes?

Remove the cowling and see how it will run. I'm thinking the O2 sensor corrosion problem if not the AIC.

I have a 2007 250 that started acting up last month. It would start great when cold, even when hot, but starting out cold it would run great without any problems. One time at the sandbar we stayed a short while, less than 2 hours, then left, it started and Idled for about 10 minutes and then stalled. Started again and stalled. And again. Pumped the primer and it ran fine from then on.
Another time stopped at a restaurant, had lunch, started, Idled out of the no wake zone, then stalled soon up on plane.
Thinking I should check and replace the main fuel filter. Did that, started and ran for awhile at the dock. Let it sit to get ready to go out on the boat and then Idled down the canal and it stalled. I cycled the key switch 3 times. And it started and ran fine. I got that idea from the link I posted. It ran fine for several hours after that. I believe cycling the switch turns on and runs the fuel pump.
Haven't used the boat in a month. Plan to go out tomorrow.

I'm not sure how old it is. The boat and motor are both 07 but I'm not sure it's ever been changed out. Thinking I'll change it since it's a cheap item to knock off the list.

No codes, mechanic didn't find any issues with spark, and it runs great when it's actually getting fuel flow.

I do remember somewhere reading that people having a similar issue had success with removing the cowling and the fuel cap. If it acts up again that's something I'm going to try.

Huh. That's interesting. I do usually just cycle the key from off to running instead of off, on, running, so that's something I'll have to try. Thanks for the suggestion.
