Re: Bilge Blower
One side vent should be to allow air into the bilge / engine room and the other for blower exhaust. I don't believe their is a requirement for which side is which.
The coast guard has requirements for how many cfm's per cubic ft, and one blower minimum is required for each "isolated" engine or equipment compartment, but without looking up the specs, I would bet only one is required for your 31, so long as it is ducted to the lowest point in the engine room on the intake side and ducted to vent outside the boat on the discharge you should be good.

Re: Bilge Blower
FEDERAL LAW:
183.610 Powered ventilation system.
(a) Each compartment in a boat that has a permanently installed gasoline
engine with a cranking motor must:
(1) Be open to the atmosphere, or
(2) Be ventilated by an exhaust blower system.
Permanently installed with regard to an engine means that it is securely fastened to the boat’s structure
and the necessary wiring, piping and controls are connected and secured to the boat in accordance with
the applicable USCG regulations. See Title 33 CFR Part 183, Subpart I, Electrical Systems and Title 33 CFR
Part 183, Subpart J, Fuel Systems. The use of the term “permanently installed” is to highlight that the
engine is not portable or easily removed from the boat and to differentiate it from “portable equipment”.
The term gasoline engine with a cranking motor is used to indicate that the gasoline engine can be
started from a location that is remote from the compartment where it is permanently installed. An engine
without a cranking motor (starter) requires the presence of a person at the engine location in order to
start the engine. Presumably, any dangerous conditions such as liquid fuel or vapors being present at the
engine location would be detected by odor and/or sight and remedied before the engine is started.
This section of the regulation addresses boats that have a permanently installed engine with a
cranking motor in a compartment. To comply with the regulation one of the following alternatives
must be satisfied:
1. The compartment must be open to the atmosphere, as defined in 183.605.
2. There must be an exhaust blower system installed to ventilate the compartment in which
the engine is installed. An exhaust blower system consists of one or more blowers with
ductwork and terminal fittings attached to the ducts.
