Hi Ryan,
Like most others, my blower (3" commonly found) exhaust via an aft cowl vent.
I don't recall anyone mention that gas fumes be
heavier than air, so the intake hose should be as
low as practical and below the lowest possible ignition point.
I have the intake laying alongside the aft port engine mount.
Cheers, Russ

Hey all,
I'm looking for input on a good blower
installation on my 1976 C&C 30 mki. I'm almost
through rewiring my entire boat and I'm up to
replacing the blower. I removed the the old
unit because the fan motor was dead. Judging
by the look of it, it may have been original.Â
The flexible hoses were connected to nothing, so
I'm not exactly sure how it was originally
hooked up. Although I surmise it exhausted
through one of the two dorade vents on the
transom. I assume the other dorade vent is
used to just allow outside air into the engeine
compartment - since there is nothing hooked up to that.
I'm curious what the original blower/air inlet
setup was on a 30 mki, and I'm I'm looking for
the safest and most effective way to clear my
engine compartment of gasoline fumes.Â
Also, if anyone has opinions on the proper size
(in CFM) of the blower(s) and the proper
diameter of the flexible tubing I'd love to hear it.
Thanks!
