Blige Blowers
I am replacing both bilge blowers in my 47 Fountain. One of the blowers sucks fresh air in as the other blows it out. I get the theory there but being the 47 Fountain has large fresh air vents on both sides would the I get more fresh air in bilge having both blow out with fresh air coming in through vents?

I believe the idea is that the blowers are meant to remove any possible fumes while the boat is NOT in motion and before the engines (two or three in your case - wow!) are fired. Also many use the blowers at idle speeds. This setup insures clean "fresh air" into your bilge while motionless or at low speeds rather than the mixture of fresh air and possible fumes you might have if you set up your blowers as two pushers.
You own my dream boat. I'm curious if you tow it and if you do with what? I have a few additional questions if you don't mind a PM. Good luck.

Sure the one wasn't installed backwards? Seems the vents are more than enough to pass air with 2 blowers pulling fumes from the bottom of the bilge, as they are meant to do
I see no benefit having the one pulling air in and just 1 pushing it out. If anything, it's cutting the circulation in half

My blowers are the 1st thing that get turned on, and they stay on till the key goes to off. No exceptions.

Bilge Blowers
The bilge blowers are designed to blow air outward. On 27,29,32 foot Fountains they were prone to get water logged when pulling back the thottles to fast. The water woud rush down the plastic tube washing out the bearings. The bearings would lock up on the fan , causing the fans to over heat and burn up.
