Nevertheless, IMO, in a true emergency, you should do what you must to respond to the demands of the occasion, and you should balance all the risks in your mind. How great is the risk that the boat will explode if you start the gas engine without running the blower, as compared with the risk that the MOB will be lost or suffer hypothermia or other danger if you don't use the engine to recover them quickly? If you can maneuver the boat under sail sufficiently to recover the MOB, then that's what you should do. If you must use the engine, are the circumstances such that you can do a quick sniff test and run the blower for a minute? If not, then your only acceptable alternative might be to start the motor and cross your fingers. There is a known risk in starting a gas engine without checking for fumes and using the blower, but, that doesn't mean that it is likely that a disaster will follow. If the alternative is that you won't be able to recover the MOB, then that might be a risk that is reasonable for you to take. IMO, you do what you must do under the circumstances.

There might be an alternative to tying up the launch ramp while you run the blower. For example, you might be able to turn on the blower and let it run while you are unstrapping the boat from the trailer and launching it, or perhaps after you launch it, while someone is parking the trailer. You can often find a convenient time to run the blower, if you give it some thought. I'm sure a lot of folks run the blower before they start the engine. Watch how they do it and learn from them.

I am real BIG on blowers BUT all these horrible events do get investigated (at least around here) and every time SOMEBODY HAS DONE A Wile E. Coyote AND used and auto electric part or a complete lack of owner care

I am always confused as to how fueling a boat with a sealed tank and the filler and vent OUTSIDE builds up any fumes unless something is broken ?

If a dirty bottom slows you down what do you think it does to your boat

Unless it's fuel injected...carburetor is vented and has overflow capabilities...

You can only recover the MOB if you can find them.

Only if the fuel pump valves are stuck open, the float valve of the carb is stuck open and the gas tank is higher than the engine.

Of all the millions of power and sailboats that are powered with gasoline engines, the percentage that meet their untimely demise in this manner is a tiny fraction at best. I suspect more people are struck and killed by lightning in the U.S. than there are gasoline powered boats exploding. Hmmm! I just looked that up, and the number of folks in the U.S. killed by lightning strikes each year is an average of 39. I couldn't find the number of boat explosions, but I'm sure someone here can provide this information.

It's been two years since my last MOB practice under sail. (I sound like an alcoholic!) Well, apparently that's how long it takes to be rubbish at it. It took 3 goes to get the lifebuoy back. From now on, we're practicing it once every trip!

Practice those MOB procedures, folks.
