![]() You connect the other end of the blower to a bilge vent on the outside of your boat. Typically, you attach the blower to a hose that goes down to your inboard engine compartment. For this purpose, boats utilize a device called a bilge blower.Ī bilge blower (or blower motor) is a small exhaust fan that you install in the transom of your boat. To prevent this from happening, the boats must exhaust the gases to remove the risk of explosion. A tiny spark or static charge could cause an ignition, exploding your beloved boat to smithereens! If these gases are allowed to build up inside your boat. Please leave your thoughts and comments below.Inboard engines can cause hazardous and potentially flammable gases to build up inside the engine compartment of your boat. If you know anyone else wondering about bilge blowers, don’t hesitate to share this article with them as well. It’s a good idea to protect ourselves by knowing how to use our tools effectively. While it may seem like a lot of trouble, the risks that come with gasoline fume buildup can be life-threatening. Now you have a better understanding of the bilge blower on gasoline powered boats, when should the blower be operated?. ![]() And it’s a good idea to consider them if you expect to use low output engine operation. However, there are blowers intended for heavy use. However, blowers are usually not designed for continuous use. It may seem like a good idea just to keep the blower operating during such times. Fumes may accumulate more quickly in these situations. This is due to the decreased air intake leading to more unburned fuel mixed with the engine exhaust. Running the engine at low output.Īnother good time to use the blower is operating the engine at a low output for extended periods. Use the blower as dictated by the situation. Check to see that everything is well on the boat first and that no fuel has spilled out. Of course, inspecting an unused boat thoroughly before starting it up is a good idea. It’s a good idea to clear the air out properly before starting the boat. Before starting an idled boatĪ boat that has not been used for a while may have gasoline fumes accumulated in the bilge, and there may be more fumes the longer the boat was left unused. It’s a good idea to check for the smell of gasoline and extend the blower operation time as needed. While 4 minutes is the recommended minimum operation time, this may not be enough to clear out the fumes completely. At the same time, refueling may cause fumes to build up even more. It is essential to keep in mind that the blower should be turned on only after refueling, as operating the blower. We have to clean any spills since the spilled fuel will continue to emit fumes and render the blower useless. It is recommended to always use the blower before turning on the engine after refueling to clear out any gasoline fumes that may linger. Below are some situations where it is best to operate the blower. However, as blowers are not usually designed for long periods of use, it is best to designate specific situations for using them. The blower should be turned on at a minimum of 4 minutes to allow the blower enough time to clear out the buildup of fumes. However, it should always be used before turning on the boat engine to clear out dangerous fumes. There are many situations when a ventilation blower should be operated. It is among the requirements for ventilation systems as prescribed by the US Coast Guard for specific vessels that use inboard engines. Using just any fan is not an option.Ī bilge blower is an integral part of the inboard gasoline boats ventilation system. These blowers operate while also eliminating the possibility of igniting any fumes that may have built up. Blowers are specially designed with the risk of such fumes in mind. The bilge blower serves to remove this buildup.Īside from the strong smell of gasoline fumes which is harmful, there also exists the risk of the fumes igniting, which may cause a fire or something even worse. Gasoline fumes that leak out of the engine accumulate in the bilge, which is the lowest part of the boat. For boats that use an inboard engine, the risk of gasoline fume buildup is an important consideration.
