Why Must You Operate The Exhaust Blower Before Starting A Boats Inboard Gasoline Engine?

Should you do before starting an inboard gasoline engine?

What should you do prior to starting up the gas-powered inboard motor? Prior to starting up the inboard motor, check for vapour odours. If you have a gaz powered inboard motor, the blower must be operated for a period of at least four (4) minutes. This will enable any dangerous fumes to fully evaporate.

When should a blower be operated on a boat?

If your boat is equipped with a power ventilation system (exhaust blower), turn it on for at least four minutes before starting your engine. This will help eliminate fuel vapors in the bilge. Before starting the engine, sniff the bilge and engine compartment for fuel vapors.

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.

Should a boat be stored with a full tank of gas?

Filling the Tank

Marine engine manufacturers and technicians advise storing any boat with the fuel tank almost full, leaving just a little capacity to accommodate expansion of the fuel if the temperature warms. This can occur if the boat is stored outdoors or in an unheated building.

Why should a boats gas tank never be completely filled?

It’s important to never fill the tank of your boat beyond 90% full. This leaves room for gas to expand and avoids the potential for overflow. After you’re done fueling, tightly replace the gas cap. This will prevent the escape of fuel vapors.

Do you leave the blower on a boat?

You need to also turn the blowers on (or leave them on) between starts when you are using the boat for water sports. Each time you shut down you risk fuel build up and you‘ll have people climbing in and out of the boat don’t restart if you haven’t run the blower.

What is the purpose of a blower on a boat?

In gas-powered boats, there should be one blower for each engine. The blower’s 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.

How many minutes should a blower be operated?

DANGER: To prevent a possible explosion, operate the blower for at least four (4) minutes before starting the engine and always when at idle or slow running speed. Explosive gasoline and/or battery fumes may be present in the engine compartment.

Why do boats explode after refueling?

Any watercraft with an inboard gasoline engine has a very real potential to explode. This is largely due to the buildup of gas fumes within a confined space, such as the bilge or an engine compartment. These gas fumes could possibly ignite and quickly spread, ultimately leading to an explosion.

How do boat blowers work?

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. The blower clears out the fumes and makes the fume air mixture too lean to explode when the engine is started.

What should be avoided when anchoring?

Never tie the line to the stern: the additional weight could bring on water. Slowly lower the anchor from the bow, rather than the stern, to avoid capsizing or swamping. When the anchor has hit bottom—and sufficient rode is given out—give a solid pull to set the anchor. Secure and adjust the line.

How long does it take for gas to go bad in a boat?

The pure gas tends to lose its combustibility because of evaporation and oxidation. Such gas is said to last for only 50 to 90 days. In other words, the brand new sealed tank of gasoline can stay good for 120 days but used, or old gas has a life expectancy of about 90 days at most.

Do boats require a lot of maintenance?

Annual maintenance is roughly 10 percent of the cost of the boat, estimates Bloomberg.com. That includes painting the hull every year, cleaning the deck, and replacing the sails every few years. So for a $20,000 boat, that 10 percent comes to $2,000 annually.

Can you use too much fuel stabilizer?

Fact is, you can use too much Techron and cause damage to your fuel tank lining. You mention the vehicle runs better after you use it. After you have it down that low, you should probably take around 15 gallons of fresh fuel.
