Too many stories of people blowing their motor covers off not to run it every time.

Every time before I start the engine. The flip of a switch could save your boat from blowing up. The flip of ONE switch! Simple, do it every time.

I'd like to say every time I start the boat (and that's how I voted) but truth be told I do it only if we've been sitting for more than 20 minutes or so. If we're changing up riders or if we've just stopped for a couple minutes I'll forgo the process. More than 20 minutes and it's an automatic part of the start up procedure. So I'm saying 95% - 98% of the time. It should probably be 100%.

not work the risk. I flip the switch then load our gear, gives lots of time.

Sounds like me. However, loading experienced skiers I don't turn off the boat. Newbie's I will turn it off.

I've never heard of this happening... But if you know some good ones, please share!

Wouldn't this be more of a concern with carb engines vs less with an efi?

I tend the run the blower about 75% of the time... I have buddies have that never touched their blower, and buddies that run it 100% of the time the engine is even on

My blower is on just about any time the boat is under 25 MPH, just for that little bit of air circulation. When my wife is driving, the blower is on 100% of the time because she can't reach down to flip the switch and drive at the same time.:D

Do It
04-03-2012, 10:32 AM
I run the blower for a couple minutes before ignition every time I'm out on the water. I don't leave the blower running, but I do run it before we start if we're sitting for a while.

About 25 years ago I witnessed the aftermath of a family getting blown out of a boat due to an explosion during ignition. I was a kid, so I don't remember the exact details. All I know is the guy borrowed his buddy's boat, somehow got gas in the hull (Supposedly by over-filling the gas tank, but I have no idea how that could happen), started the engine without knowing about the blower, and kaboom. It blew all of them out of the boat, started the marina on fire, and at least one family member was sent off to the hospital. Pretty sure the use of the blower would've helped prevent this. Maybe not, but ever since seeing such a terrible situation I've been adamant about implementing the blower before ignition rule. Watching something like that'll make it pretty easy to remember.

Whats a bildge blower? kidding of course. I understand the purpose, but at the same time the intent confuses me a little. Given there was enough vapour accumilation to ignite an explosion when attempting to start an engine, would that risk still exist with turning on any potential ignition source... say like turning on a powered fan? unless the fan is hermetically sealed like what is used in a class 1 div 2 (explosive) environment. just saying... But I still use mine before starting :)

I've gotten in the habit of doing the same thing. It started that I just forgot to turn it off while we were idling, but now turned into normal practice.

I've actually even noticed I get a few more RPMs out of the motor with the blower on... especially if it is hot out.

You should run the blower for 5min prior to starting the engine per the instructions. So my question to all of you who claim to run it prior to every start is this: are you running it for 5min then starting, or just turning it on then starting seconds later. It stands to reason that in order to reduce the risk of an explosive environment you need to give the blower enough time to actually do its job.

I answered that I only run it before the first start. But I actually forget to turn it off most of the time until we are coming back to pick up the first fallen skier and I hear it still running. I then don't turn it on again unless we have sat with the engine off for a significant amount of time. What exact is significant? I don't have a good answer. Probably a few minutes less than however long I will have been sitting there when I go to start and my boat blows-up.

I agree with Brooks. I typically open the engine hatch at the begining of each weekend. It's too easy to run the blower. Who wants to risk it?

pram

If and I stress if, your fuel system is operating correctly, the risk is minimal in my opinion.

the following is accurate as far as I can deduce

For those of you that run the blower at speeds less than 25mph, do you realize that for every gallon of gas you burn that you are consuming approximately 43.6 CUBIC YARDS OF AIR??

or for us Canadians

every litre of gas burnt consumes approximately 8765 Litres of air

that is a pile of air to be worrying about running your blower below 25mph IMO

If your fuel system is operating normally, isn't there no risk???

It is when there is a leak of some amount, however small, that the gas fumes have the potential to turn your boat into a bomb when you hit the key without thorough ventilation.

Aside from always running the blower prior to starting, I always open the engine cover to check the oil level prior to each days operation.

Perhaps a 5 minute tone would be something to incorporate into the blower motor operation.

I am also in the camp of running mine 100% of the time. I get in and turn it on for a couple of minutes and then start the boat. When done using the boat, the last thing I do is turn off the blower. My boat is 12 years old and still has the original blower in it.

better yet, why not have a sensor that automatically turns your blower on and off?

In today's litigious society, I am surprised that no one has sued thus forcing an auto on-off blower motor be installed.

Just like the auto bilge switch

Shhhhh don't tell anyone this idea, I am going to patent it and make my millions

pram
04-03-2012, 01:53 PM
Gasoline vapor is heavier than air right?

How much of a leakage do you have to have in order to fill the engine compartment to the point of explosion?

in a correctly operating fuel system, what would have to transpire to cause the engine compartment to fill with gas vapors?

what is the percentage of boats that explode compared to those that do not explode?

with the fuel being heavier than air, if there is no breeze, would the gas vapors dissipate when you open the motor cover?

Actually, post fueling has been reported to a common cause of gas vapor accumulation based on a study that showed post fueling is a common time for explosions to occur. Theoretically, having a hatch open, or any access to the bilge, or running the blower while fueling, would make your chances of explosion greater.

I was shocked to read how many boats blow up because the captain left the boat running while being fueled!

This happened to a friend of my nephew a few years ago. They had been skiing for a few hours, then parked their late 80's Prostar at the end of the dock and went in to eat. Came out an hour later, hopped in the boat, hit the key and kaboom! He was blown onto the deck but not seriously injured.

My Maristar 200VRS has two 1/2 inch bolts for the rear hinges and the hydraulic lift cylinder holding it down. If there is an explosion, something is getting blown apart.

The sensor is a great idea. Turn the key and if the blower goes on before the engine will turn over you have fumes. Once the concentration goes below a certain level, the boat will start.

But this may actually increase MC liability. If the system failed, they would liable. Currently, if the boat blows up it is owner error, not equipment failure.

Those cylinders would open right up if gas vapors were inadvertently ignited. Your 1/2" bolts would be just fine, but the hinges would likely be ripped right off the motor cover.

My one cylinder is the hydraulic powered unit that raises and lowers the rear sundeck. I'm sure it would stay in one piece, but every screw would get ripped out of the sundeck.

I'm sure the odds of an explosion are small, but if there is an accident there are usually several factors that lead to an explosion. I'm not going to add one more factor by not running my blower...I've replaced it several times. I guess I just don't live "on the edge" like some guys!!:D

After all these posts, and not a mention of a Mastercraft blowing up, I feel a little better about the subject. I rarely used my blower prior to last weekend. When I removed my floor panel to install the plug, a very strong fuel smell hit me. I had just topped off the boat and pulled it to the lake...... The smell was strong enough to alert me to the point where I opened up the hatch and ran the blower.

Anyone else have issues when topping of their MC? Every time I try to top my tank off I end up spraying fuel everywhere. Any solution to this?

No problem topping off the MC per-say. I actually try to keep mine at 1/2 or less so I have a smaller wake on my ps205 for skiing. But I usually het a splash of fuel at the end when I try to fill the tank all the way. Many others have all said the same thing. Unlike cars/trucks boats don't have that little overflow preventer thing in the fuel fill hole. So my best fix involves a bunch of paper towels and the window washer squeegy.

I run mine when we load gear on the boat before I drop it in the water for a few minutes. It stays off the rest of the day unless we stop the boat for over 15 minutes.

Note: A quick solution for those that are impatient...lift the engine hood before starting. That is the most effective way to get the gasses out.

I asked a customer why the insulation inside the motor cover looked scorched and he said his daughter was trying to start the engine but it wouldn't fire. Someone then put the lanyard on and she tried it again, igniting the fuel vapors (carbureted) and blowing the cup holders out of the cover. Scared the shyte out of her but it could have ended very badly. It was a good thing the cup holders were there to relieve the pressure.

The manual explicitly indicates when and how long the blower should be run but apparently, most people don't read this, or the manual in general. Reading the manual could save some people a lot of trouble and expense.

I have actually seen a flash fire and engine cover blown open from fumes in the hull. I was waiting to launch my boat one time. Yahoo's everywhere. Two idiots in the ramp trying to get their boats off of the trailer. Another idiot tied up to the off side of the dock where I was standing watching this circus. He kept cranking and cranking on his inboard. They had a guy sitting on the engine cover. I noticed that it wouldn't start and he was steadily cranking it over. Wind shift a little and I got a good whiff of the gas fumes. I knew that dog was flooded. Just said something to my buddy and----whoosh. Engine cover flipped open and catapulted the fool sitting on it into the river. I watched him do a couple of slow somersaults before splash down. He had third degree burns on his legs and arms. The two fools sitting in front both had burns to their backs, necks, and hair. Never forgot how surreal it looked when it happened.

I pay pretty close attention to any kind of fuel smell. And fix it immediately!
After trailering to the ramp... don't run it
After sitting for more than 5-10 minutes definitely run it. While in the open water (after skiing) probably don't wait 5 minutes TBH
After sitting in the swim bay forever, Once its established that we are heading out I turn on the blower, pull in anything hanging off the platform and haul in the anchor. After all is said and done typically over 5 minutes.
After we are moving I turn it off. Some times if idling around for long periods I'll turn it on.

Stutsman230
04-04-2012, 03:08 PM
I always open the engine cover and smell for fumes when we pull up to the ramp at the beginning of the day. Then I still run the blower while loading the boat before launching. I always smell for fumes when pulling equipment out of the back side lockers.
I will run it after sitting for more than 5 minutes or when we are under 5 mph going up a very long (>1/2 mile) no-wake zone.

Better than being blown into traffic on a busy road.

Difference if running? If the cap or plug wires are allowing voltage leakage, yes- the fumes could easily ignite. If the engine backfires, yes- even with a flame arrester.

I was reading some of the Darwin Awards stories and one guy, I think in Arkansas, was outside having a "few" with his friends one night and they saw a raccoon scamper across theyard. They chased it into a drainage pipe that was installed on an angle and thought it would be funny to get it out, since they knew the other end had a grate to keep anything from clogging it. They poured gasoline into the pipe and waited. Nothing. They poured a bit more, then waited. Crickets. One of the guys decided that he would crawl in and see if the raccoon was still there and he went in, head first. Realizing that he couldn't see anything, he took out his BIC lighter. One of his friends said "There was definitely a Doppler Effect thing going on as he flew overhead", having been shot out of the pipe like a cannonball. He wasn't in bad shape, considering. Must have landed on something soft, like his head. He said "If I knew, for a fact, that I wouldn't get hurt, I would do that again".

gasoline engine with a cranking motor must:
(1) Be open to the atmosphere, or
(2) Be ventilated by an exhaust blower system.
(b) [contains AMCA standards]
(c) [contains AMCA standards]
(d) Each intake duct for an exhaust blower must be in the lower one-
third of the compartment and above the normal level of accumulated bilge water.
(e) More than one exhaust blower may be used in combination to meet
the requirements of this section.
(f) Each boat that is required to have an exhaust blower must have a
label that:
(1) Is located as close as practicable to each ignition switch;
(2) Is in plain view of the operator; and
(3) Has at least the following information:

I didn't know this until this thread got me to wondering.... hummmmm........

I know it says 5 min, but I bet hardly any of the people who claim to do it every time actually wait five min by the clock.

Ya know, if you guys keep discussing this and someone from the Gubmint sees that most people aren't using the blower, they're gonna make it impossible to start the boat without using it.

Wouldn't that suck....and they'd probably put a breathalyzer component there with it and we'd all be screwed...

A careful reading of the law reveals that it is not a law to run the blower, only to have a warning label as noted. No requirement for you to actually run the blower.

I run it when I remember. Always the first time starting for the day, but then again the doghouse is always open for a few minutes before going in the water as well to check oil, belt, plugs, ...

I try to run it before restarting each time if sitting for more than a few minutes. A few trips ago when I was out, I forgot to shut it off for about an hour and a half. When I finally realized it was on, I shut it off. Last time out, I noticed that the fan blades had basically disintegrated when the blade came out of the housing. New blower ordered and delivered this morning. Just need to find some new hosing to run to the transom and it will be set again. So the last time I was out, I just made sure to open the doghouse when idling or shut off (which was easy since I was diagnosing things the whole time :))

When I first bought my 97 prostar in 2004, I used the blower that whole summer before I cranked the engine. Then when I dug into the engine compartment to winterize the boat. I found that the blower hose was falling apart and not even one solid hose. I pretty much but 40 hours on the boat without ever using the blower. I have a new hose now, but I don't use it on every engine crank.

Every time its a cold start. Changing riders or a quick stop dont do it. Been sitting for a bit I run it. Better safe than the alternative.

Well I know when I took the Texas boaters safety course to get my insurance 10% cheaper, it was a test question, and the answer is 4 min...

I guess since it's a requirement to have the warning label that you must also follow the warning label, just like the label that states how many persons can be in the vessel....

Like there's Gunna be a copper standing at the dock with a stop watch anyway lol

I figger the 20 min ride to the lake probably airs things out pretty well, but I still flip it on if I remember. I used to pay more attention to it on the carb boat- F.I. don't worry me too much. I do like to open the hatch before the first start-up of the day.

This thread sounds like the seat belt issue!!.....We all know that they save lives but not everybody uses one!?!?!? Something I've NEVER understood!!!
If running a blower can prevent fire, pain or death it's use is a no brainer for me!!

I'm glad this thread was brought up cause it will help me remember to let it run a little longer before start-ups then I do sometimes....
Kinda like many years ago when I was among the first on the scene of a car accident and the image of the guys crushed head that smashed through the windshield as he layed partially in the windshield and on the hood has kept me buckleing the belt every time I sit in a car!!...

I run ours constantly. Besides a little whisper of air in the background, what's the downside of having it on?

I run mine continously as well. Better SAFE than SORRY!!!

Has anyone heard of an explosion with a fuel injected engine? Seems to make a lot of sense to run the blower on a carburatored motor, but on a closed fuel injected motor??
