Here is a lil news story and pictures from a recent event on Lake Lanier in Atlanta. Long story short, a boat exploded while fueling at the Marina.

Do you just let the blowers run non-stop?

no, but start them before you open the gas cap

never let it run non-stop, it will starve the engine compartment of air. just anytime before re-starting and long enough to ventilate (2-4 minutes) and/or maybe open one of your engine hatches or motor hatch to help with the process..

those pics are a scary situation to think about!
glad nobody (else) was filling up in the next slip over..

use the blower gas fumes are heavier than air and will sit at the bottom of the boat hense the reason the blower tube is always down in the bilge.

If my engine is running, my blower is running. I've never noticed any adverse effects to the motor or how the boat runs. I also run it for a short time before start up.

Yep, I run mine all the time.

There's definitely no way you are going to "starve" the engine compartment of air with a little bilge blower!! I imagine that the air you are exhausting with the blower is being replaced at an essentially equivalent rate by air coming through one of the many pathways from the atmosphere to the engine compartment.

The engine compartment would have to be nearly airtight and you'd have to have a pretty darn strong motor to create even the smallest of vacuums inside the compartment.

That being said, I don't run mine as often as I probably should.

I run mine before I start the motor and whenever im in a no wake zone or idleing.

clarification: not completely "starve" (figure of speech) but enough in the past where my boat has had difficulty in re-starting when my wife has left it running during a pull.. meaning, "starving" of it air, does that work better for you guys?.. just trying to support the whole air/fuel mixture thing for fuel injection..

Run your blower while fueling and whenever your boat is running and not on plane. It will in no way effect the way your boat runs. (starve engine for air)

The blower picks up the heavy gas fumes that might be in the bilge. When the boat is on plane there will be enough air movement to flush gas fumes out of the bilge.

i always turn mine on before I start the boat a couple years back a buddy of mine fueled up and didn't turn his on and it damn near blew the thing in half pretty scary stuff

This is a practice I have moved away from for some reason....good advice and time to reimplement the blower.

Do people turn on the blower while refueling on land?
Old    walt            05-06-2008, 4:23 PM Reply   
It's not a bad idea to pop your engine cover open and take a sniff before launching too.

There's no ignition so there's no point.

Yup.... good points guys. We used to always run the blower when filling up and when starting the engine. I honestly probably haven't done it in a couple years now. Tisk, tisk.... I'll try to get back in the habbit of it.

Wow, unreal picture.

I bought my first extended pylon from a guy who's boat blew up. Seems like he runs a board shop now days in Richmond.

Its amazing that noone died in the explosion. The lady was lucky to escape with minor burns and scrapes but the other two were burned kinda bad.

I find it hard to believe that not running a blower would be the cause of that. They had to have some sort of major gas leak going on.

???? wow! I am def changing my ways. Used to never turn it on, except on starts when first launching. With my kids in the boat/or anyone..."better safe than sorry"!

I read a article about the subject a few years back and was amazed at how little gas it takes to make a good size explosion.
Old     (sidekicknicholas)      Join Date: Mar 2007       05-06-2008, 8:47 PM Reply   
our blower has been hooked up to another bilge pump

'While attending a boat accident investigation course a few years ago, I learned that fumes from a single cup of gasoline spilled or leaked into the bilge of a boat could result in an explosion equal to that of several dynamite sticks. It then would be logical to believe that dissolving fuel tanks could lead to an explosive situation.,-Fibreglass,-and-now-Biodiesel-warnings/43885

Most boat fires and explosions occur shortly after refueling. Gasoline fumes are much heavier than air and can collect in the lower parts of a boat, such as the bilges. One cup of vaporizing gasoline has the explosive equivalency of 15 sticks of dynamite.

To reduce the risk of an explosion occurring:
Before fueling, turn off all engines, motors and fans and extinguish open flames. Close all ports, doors, windows and hatches to prevent fumes from entering enclosed areas.

While fueling, keep the nozzle or spout in contact with the mouth of the tank to prevent the buildup of static electricity from producing a spark. Tanks for outboard motors should be filled on the dock or on shore. Be careful not to spill any fuel or overfill the tank. Always allow space for expansion of gasoline to prevent overflowing.

After fueling, close tanks and wipe up any gasoline spills, properly disposing of the wipe-up rag on shore. Open all ports, doors, windows and hatches and turn on the exhaust blower. Ventilate the boat for at least five minutes and sniff in and around the engine compartment before starting engine. Although your nose is the most reliable detector to determine whether gasoline vapors are present, consult a marine dealer about electronic vapor detectors which prevent the ignition from starting if fuel vapors are detected.

Maintaining your boat can also reduce risks. Regularly inspect the condition of fuel lines. Look for loose connections, cracked hoses or other leaks. Keep the flame arrestor clean and securely attached to the carburetor.

Walt what do you mean by this?

"dissolving fuel tanks"
Old     (mikeski)      Join Date: Aug 2003       05-06-2008, 8:58 PM Reply   
Your nose is your a friend when you own a boat. Learn what the different smells mean, I agree with Walt, running the blower before starting is good but take a sniff when you make that last check double check that your plug is in.

Gassing at the marina is always somewhat sketchy, tons of opportunities for explosion or electric shock. I prefer gassing on the road before a good 65mph wind gets an opportunity to push the fumes out the back.

I have been boating all my life, I have been on fire twice in a boat. It happens quicker than you think. It also helps to understand that it takes air, fuel, and a spark to make fire. Once it's started you need to eliminate one of the first two to stop it. Sometimes a wet towel is more effective than a fire extinguisher on small fires. Acting quickly is key once a fire gets moving.

i can understand fumes here and there but how does fuel get spilled like that into the bilge? If it did wouldnt it just mix with the small amount od water thats always in there.

Clint, gasoline burns but gas fumes blow up. You get a much bigger explosion from dropping a match in an empty gas barrel than you do if you drop one into a full gas barrel.
Once you've got the explosion everything gets hot enough to burn. Oil in the bilge, upholstery, carpet, gasoline, etc.

Running the blower gets rid of the fumes, that's why you need to do it when you idle or before starting. It takes a while to clear all the fumes, just like that bathroom fan. That's why they want it run for several minutes.

Wow that is an eye opener We have been trying to remember to turn it on with the new boat our old boat had an automatic blower

Pitty your passengers if you don't believe this can happen from not running your blower.

When carbs were the norm on boats this was a lot more common. I knew some guys in Canyon Lake who had an old CC 2001. They had replaced the carb on it at some point & apparently something didn't get put back together right. Several days afterward the boat burned to the waterline because they didn't run the blower & the carb/fuel line must have leaked a bit.

I run the blower then open the hatch for 1 min then start the motor this is a good time to get a look at the eng compartment. When fueling I run it on the way to the fuel dock {no wake zone}them kill all power to the boat and open the rear hatch.

Its important to remember that WHILE Fueling, you do not want the blower or anything else running.

"To reduce the risk of an explosion occurring:
Before fueling, turn off all engines, motors and fans and extinguish open flames. Close all ports, doors, windows and hatches to prevent fumes from entering enclosed areas. "

You know, you would think that with these dangers that boat companies would devise some sensors in our engine compartment that automatically turn the blower on. I neglect using mine sometimes too. I don't run full speed around the lake, most of the time I run as slow as it will go to keep from tearing up the lake. Going slow like that I would think that the blower should be running. This is a good thread, and good things to be aware of.

I read about the dissolving gas tank thing recently. I didn't read Walt's link, but in a nutshell, lots of older boats (typically bigger boats and fishing boats for ocean use) have fiberglass gas tanks that are prone to being eaten up by the somewhat recent addition of ethanol into gasoline supplies.

The article I read featured a couple guys whose tanks literally melted away after some time and required expensive overhauls and repairs.

Walt's quote must have been referring to the hypothesis that dissolving tanks likely leads to gasoline vapors in the bilge and potential explosions.

I know all the new ski/wakeboard boats use plastic-based tanks and thus are not susceptible to being dissolved by ethanol, but I wonder if any of the older ski boats ever used fiberglass tanks.

My 78 master craft had an aluminum tank.

My 77 century had an aluminum tank,

My 85 searay had an aluminum tank,

my 87 magnum had an aluminum tank,

my 91 nautique had a plastic tank

my 93 nautique had a plastic tank,

my 98 nautique has a plastic tank.

man that sucks about the guy at the dock, that would ruin your summer.

I am sure that running the blower at any time is a good safety precaution. But, by design, the fuel system is sealed. It has one input and two outputs. The input is obviously where you fill the tank. One output is to the engine and the other is a fuel tank vent. The fuel tank vent is on the outside of the boat. For fuel (vapor or liquid) to enter the engine compartment would mean there is a malfunction somewhere in the fuel system, i.e. cut, crack, looses fitting, etc. Personally, I run the blower almost constantly because I forget to turn it off after putting the boat in the water. Also, I store my boat with the engine cover open; mostly to help the boat dry out.

Damn! That's the marina where I drop my boat in every weekend. I'm glad I wasn't there at the time.
