These vapors are highly explosive and if ignited by a spark can destroy the boat and anyone on or beside the boat. The blower on a boat is turned on before energizing the ignition of the engines and run for a couple of minutes.
Wire the blower in series with a Klixon thermostat so it only runs when necessary.
What is a blower on a boat. A bilge blower or blower motor is a small exhaust fan that you install in the transom of your boat. Typically you attach the blower to a hose that goes down to your inboard engine compartment. You connect the other end of the blower to a bilge vent on the outside of your boat.
The blower on a boat is turned on before energizing the ignition of the engines and run for a couple of minutes. This is a feature on inboard gasoline engine powered boats. Gasoline fumes being heavier than air can settle in the bilge of the engine compartment and turn the compartment into a bomb.
It is a device to blow explosive gases out of the bilge so that they do not blow the boat up after fueling or in case of a small leak in the fuel system. The bilge blower should always be turned on and run for 5 minutes following fueling before starting the engine. The blowers primary job is to remove any gasoline vapors in the engine room.
These vapors are highly explosive and if ignited by a spark can destroy the boat and anyone on or beside the boat. The highest risk is when the fuel tanks are being filled at the dock. What is the blower switch on a boat for.
The blower on a boat is turned on before energizing the ignition of the engines and run for a couple of minutes. This is a feature on inboard gasoline engine powered boats. Gasoline fumes being heavier than air can settle in the bilge of the engine compartment and turn the compartment into a bomb.
Why do you run the blower on a boat. The blower on a boat is turned on before energizing the ignition of the engines and run for a couple of minutes. This is a feature on inboard gasoline engine powered boats.
Gasoline fumes being heavier than air can settle in the bilge of the engine compartment and turn the compartment into a bomb. A bilge blower evacuates bilge air and therefore pulls fresh air from outside of the boat into the engine room. The blower is an essential safety device.
It could save your life. On older petrol powered boats with carburetors I would rather swim the Atlantic than start an engine that does not have one. On a hot day your engine bay will get warm.
Any fuel vapor will collect in the engine bay. Blowers are installation equipment that provides the transfer of air in the emitted environment at high or low pressure and rotates the fan with the force received from the motor. Blower is a plumbing equipment that rotates the fan with the force it receives from the engine which transfers the air in the emitted environment at high flow or low pressure.
Explosions on boats are quite common because of this. When your boat is underway there are vents that keep the fumes from building up in the compartment but when you shut it off there is no wind to keep the enclosed space fresh. You can follow the air tubes from your blower to see where the intake and exhaust tubes go.
A Roots Blower is simply an extremely powerful blower used in water gardens. This device will force water from beneath the ground to the surface of the water garden. Roots Blowers come in a wide variety of styles designs and sizes and are generally used by professional landscapers and designers to create grand sweeping bouquets of water.
You can make this system work with a single blower if your engine is small enough by sealing a hose directly to the intake or spark arrestor from a clam shell no blower. Its suck fresh air from outside the space and a second hose with inline blower can remove heat and fumes. Where is the blower located on a boat.
A bilge blower or blower motor is a small exhaust fan that you install in the transom of your boat. Typically you attach the blower to a hose that goes down to your inboard engine compartment. You connect the other end of the blower to a bilge vent on the outside of your boat.
If your boat is a light boat with a large HP to weight ratio and a slow driven blower then referenced PVs may be desirable in that application. If its a cruiser or large out drive and you spend a large portion of your time in a boosted or close to it condition then PVs are next to useless. As Dream said yes I believe this is the only low cost inline blower that is spark proof.
The boat came with Atwoods which are not. On an aside I do the sniff test as well. Last week I stuck my head over the blower right after I turned it on and literally almost inhaled a giant wasp.
Buggers built a nest in the blower. Wire the blower in series with a Klixon thermostat so it only runs when necessary. That is a coin size device you can screw or glue on a known hotspot.
It switches at a fixed threshold and is available in 10 degree steps for approx. Installing a Bilge Blower Makes Vintage Boats Safer. By Dick Werner Brent Howard.
As we are all well aware we have that highly explosive liquid on board many of our old boats call gasoline. That liquid is very capable of vaporizing and releasing fumes. Two boat explosions at Lake of the Ozarks docks this summer sparked important discussions about safe refueling and in particular the correct use of a boats blower.
It seems that blowers have been discussed a couple of other times and that no real definitive solution came of them for classic runabouts. John makes a good point a blower in one of the forward vents cuts off half of the fresh air to the engine compartment while under way. Many boats come in with the little Turbo or In-Line blower motors.
Some work when tested. He will not sell them because he knows full well that they will be returned shortly. Any boat that has a permanently installed engine with a cranking motor starter must have a powered ventilation system.
That simply means almost any inboard gasoline powered boat must have a blower built into the exhaust duct. You must have a label called a Blower. A bilge blower is important not only because the USCG may require it but also because your life may depend on it.
The Coast Guard stipulates the use of a mechanical ventilation system for all non-open type boats built after July 31 1980 which run on gasoline. Even if your boat is older it still must conform to USCG minimum. The engine compartment ventilation blowers are universal in these boats.
I had to replace mine last year as well. They come in 3 and 4 sizes. If I remember correctly the one in my boat was a 4 - so check your boat before ordering.
Here is a link to overtons below but you can probably find them even cheaper on other websites for right around 25.
