So many vent holes, where to run everything?

[bigred177]

Where should I route all of my vent tubing? I know the tube on the stern goes to the blower and should go to the lowest point in the bilge. The black vents on either side have two holes to run tubes and the chrome vents also have holes. What would be the best way to run all of the tubing from these holes?

If your just going to go with a 1 blower setup, just plumb in your blower and forget about the rest. Leave them all open.

Well, that's easy. I was thinking I was going to have some kind of maze of tubing under there.

Thank you

the ones facing front will naturally force air into the compartment, the ones facing aft draw air out of the engine compartment.
blower sucks the air out, never pushes it in

Kinda makes you wonder why they call it a bilge blower and not a bilge sucker, doesn't it....

Right, I was just under the impression that I would need to duct the fresh air to certain places that need air more than others.

Nahhhh... All you need is your bilge blower with the ducts right down under the oil pan, and that's about it. The engine will create an area of low pressure inside of that compartment when running, and will draw in all the air needed. If you look at your boat, where the black louvered vents are. You have one that is forward facing and one that is rear facing. When that boat was built, the blower went on the rear facing vents, and that was it. All those clamshells you see somebody else put on after it was built.
