the engine will NOT "clear the bilge"..... that is why you are supposed to run the blower when operating at low speed. at higher speed it is the outside air flowing over the vent ventilates the bilge

(And Smokes previous comment about having a fume detector in his bilge area should also be taken to heart. It's cheap insurance, and just another layer of safety, along with the blower and the vents). As I said earlier..an ounce of prevention......

I've seen a few go boom myself, always pays to be careful.
I think you have the plan by turning one around, if you tie down the hose from the intake somewhere near the bilge (above any water) any water will just go in there. Putting the blower in the exhaust side saves it from that salt though, & which is great, because they don't like salt-water. I'm glad my V has an outboard, blowers are a pain.

do NOT put the engine's intake in the bottom of the bilge... very bad idea... if you ever take a wave over the top and get water in the bilge your engine will die.... if you have a backfire you will channel it directly to the most likely place to have fumes
the blower ALWAYS goes on the exhaust side and needs it's intake hose routed to the bilge above likely water level... IE 6" above lowest point... intake need only be routed to the engine compartment but not down low so as not to stir up and oxygenate any possible fumes

Interesting read, I never thought about having vents point in different directions but it makes perfect sense. My boat has both pointing to the stern and was like that from the factory, I know this as they are riveted on and it looks factory. I tend to forget to turn on the blower but I think my saving grace is I have to trailer my boat 10-15 miles on a hwy to the boat ramp. I know I am playing with fire not running the blower and it's not an intentional thing. I think I am going to do up a small check list, plug, blower, paddles, beer..
