Re: You Gotta Be Kidding!!!!
The bottom line is, there is a procedure for preparing to depart the dock on an inboard or I/O boat. The checklist is extensive, and has much more on it than turning on the blower.
In fact, clearing the bilge of gasoline fumes is only one of many categories on the checklist.
These checks include opening the hatch, sniffing for fumes, pulling the engine oil dipstick, checking the other fluids (coolant, power steering, hydraulics, etc.), inspecting the engine for leaks, checking the bilge for water or fluid accumulation, inspecting the linkages, and many others. All of it takes no more than five minutes. Ignore any of it an you may not get back to the dock.
Now add the fact that you are legally responsible for everyone who sets foot on your boat.
People call me anal and I've been laughed at because I always get everyone's attention and show them where the PFDs, fire extinguishers, and other gear is on the boat before we leave (not the least of which is teaching them how the head works!). But we've had a couple of scary situations where that briefing came in handy.
The 32-foot boat I bought just last week had a 3-foot section of blower vent hose missing. What's the first thing I replaced? You got it. I would never have known had I not looked in the engine compartment before we did the sea trial.
