Inboard motors can be extremely dangerous and even deadly if used incorrectly. Below are some hints ant tips to be aware of when using a boat with an inboard engine.
The basic disadvantage of inboard engines is that gas fumes are heavier than air. This can cause the fuel vapour to stay trapped in a small space where it is easily ignited by a stray spark. The resulting fire or explosion can be extremely dangerous.
There are a few ways however to avoid this fume build up within your boat. Firstly you should buy equipment that will monitor the build up of the deadly fumes. This will then warn you when the fume level is too high resulting in you being able to take action to avoid a disaster.
Secondly any boat with an inboard motor should come with some sort of flushing mechanism which will allow you to flush the fumes out of the engine space. This flushing should always be done prior to starting the engines. If you do not have a flushing system on board then buy one.
You should also always use your senses. Have a good look around and a smell before starting the engines. Make sure everything seems normal and ensure there is no strong smell of gas fumes. Have a quick look at the fuel lines to make sure no fuel is visibly leaking.
Vigilance is required with the use of inboard engines to prevent any problems from occurring. You should make a check list and stick to it every time prior to starting your inboard engines.
