Author Topic:   VERADO 275: Alarm "Vent SW Hi"

My dad just took delivery of a 2005 320 Outrage about 4 weeks ago. He traded his 2003 Optimax powered 320 for the Verados. On the trip from the ramp to the lift everything worked fine. We went to take the boat fishing yesterday for the first time. When we went up on plane, we received a "Port" engine warning buzzer. It read "Vent SW Hi" These are 2005 275 Verados. It also displayed a second code but we didn't write it down and couldn't reproduce it. Does anyone happen to know what this code might be. The books didn't really have exact error codes and our main tech was away from the dealer. We did talk to one of the shop mechanics who thought it might be something about fuel in a line that it should not be in. On a side note, after the maiden voyage from the ramp to the lift, the gas tanks were reading oppsite on the SmartCraft system. The Port was showing Starboard and vise versa. One of the shop guys from the dealer went down and was supposed to switch the sensors to read correctly. Yesterday was the first time the boat has moved since the maiden voyage and the tech worked on it. We seem to think he touched/switched something that is triggering the code. Someone will be taking a look at it sometime this week, I just thought maybe someone one this great forum might provide a little insite before next week. Any help would be appreciated.

Thanks,

Ken

Ken, if nobody here knows, you might try going over to the "Hull Truth" site and looking up a gentleman by the name of Glen E. I believe he either maintains a website or heads a group called the Verado Owners Group. I could swear I read once where he was cataloguing all sorts of info on Verado's for the benifit of that group. I'd be very surprised if he couldn't help you out with interpretation of this problem.

Thanks Big John.

I'll give that a try.

You might want to join the Verado Owner's Club. For information see Glen's article here on this forum.

This code is nothing to worry about.

In heavy seas or surfacing of the motor you will get this alarm. If you took a few bumps or were crossing a wake when you got this then that explains it. I always took it as fluids sloshing in the motor but I dont remember where I heard that. Just my 2 cents

Ken--I don't know about you, but if I had just bought $40,000 worth of engines, when they flashed an alarm at me I would want a better answer than any given so far to explain what should be done next.

I am continually surprised that there are no explanations provided in the owner's manual of these Verado engines (and other Mercury products with SmartCraft instrumentation) which explain the meaning of the warning messages.

And not to impugn anyone involved, but before ignoring an alarm I would darn sure want more of an authority than a posting on the internet as my reference!

Jim,

I just found out about the Verado owners club this morning. Glen is already sending me emails which I appreciate. Thanks.

Captbone,

The system started beeping in a calm channel, as soon as we went up on plane. There was no wind, no waves whatsoever. The engines were not even coming close to coming out of the water or bouncing around. Also, they were both trimmed all the way down - with the boat tabs in "Bow Down" position. The issue here is, once the code displayed, the warning buzzer keeps buzzing. When it didn't display anymore, it started again about 5 minutes later, while we were idiling. This is not something we can ignore. Per Glen's email and my dad's trip to the dealer today, I think they will figure out the exact problem this Wednesday or Thursday when they get to look at the boat. It is 3 hours away on the lift. I will post back and let everyone know what the exact problem was.

P.S. For the 15 to 25 seconds that the engines were running before the system alarm, they sounded Awesome!!!!

Thanks everyone,
Ken

I can't remember what this fault is but it has to do with the smartcraft looking for a sensor like a paddlewheel or water temp senor that is not mounted on that tach. But the config is still looking for it. But I agree with the post above, never accept web info - call the merc cust relations hotline. Too many people don't use the hotlines and accept the dealers info and in many cases many dealers are not up to speed on this stuff yet, sad as that seems.

sorry - bad info..the above is for another fault code - I have a email into the merc techs to get the answer on this - stay tuned...

I do completely agree with checking it out with Mercury. You never do know who is giving what info on the internet, and if i spend $40k plus on motors, I would want to know what caused it and why also. Good luck

With a modern engine like a Verado, any alarm is probably recorded in the engine controller's memory. This can be a blessing and a curse. If you sail off into the sunset with an alarm blaring, it could be used against you if a warranty dispute came up in the event of a later malfunction.

Modern engine controllers can keep track of many conditions and record them. An off-topic example: recently in our area there was a high-profile and very tragic two-vehicle auto accident. The adult male driver of one vehicle was found to be intoxicated. The adult female driver and two young children in the other vehicle were killed. An investigation of the vehicle driven by the intoxicated driver found that the engine control module showed there had been no application of the brakes on that vehicle in the time frame immediately preceding the impact. Prosecution in this case is still pending. I have a strong feeling that this engine control module evidence will be used against the driver. He might very well be convicted by the testimony of his engine control module!

Ken here is your answer straight from the merc engineers:

There is a solenoid vent canister that vents off the pressure in the FSM (Fuel System Module). There is a switch just below it (32 in the picture below) that monitors this pressure. If this switch is bad you will need a new one. I would loosen the fuel line and let the pressure off then repower the system prior to assuming that the switch is bad. I have seen people try to prime the verado fuel system with and activate this switch.
Loosen the hoses on either side the canister switch to remove the pressure. If this does not fix it then warranty the canister.

It means that the float switch in the vent line has floated up meaning that there is fuel in the vent canister. Sometime it is because the float switch in FSM is stuck and the FSM has overfilled up into the vent line or
it could be a little fuel but mostly fuel vapor causing the float switch to go high. If that is the case the pressure in the fuel system may have to be relieved to get rid of the fault. See the water in fuel part of the owners manaul - there is a buttone you push on the line to releive the pressure.

The engine controller also monitors speed and retains it for
five seconds, stopping if the air bags are deployed. In some
states a court order is required to retreive this info.

Drunk: I was only going 55 in the 55 zone.
Judge: Your computer says 95. GUILTY.

That's the greatly abridged version of a recent case.

Hey, is there a site like this for Optimaxes? I have problems with them.
jimh posted 01-20-2006 10:11 PM ET (US)     Profile for jimh  Send Email to jimh     
This website concentrates on Boston Whaler boats. Many newer Boston Whaler boats are now sold with Verado motors. Owners of Boston Whaler boats share information here. The website has been on-line since 1994. The website provides nearly a gigbyte of data, most of it text. In the reader's article collection there are about 344,000 articles, including the 8 contributed by Glen.

Tesija...try starting a new thread here.....Optimax Problems.
Describe your problems and let's see what happens.

I had the exact same problem with my 250 hp Verado. Dealer was advised by Mercury to replace the fuel sensor module (not sure I got the name right). I will pick the boat (2005 235 Conquest) up later this week and let you know.
