In theory yes,the purpose is to vent the compartment so as to not build up excessive fumes. That being said with todays EFI engines if you find you have a high concentration of fumes you have a problem see a service provider.Most issues are with carbuated engines or improper fuel delivery. Back several years a boat was fill via the pump out at which time it made its way into the cuddy,well someone thought it a good idea to take a shop vac to get it out with horrible results. I have an EFI engine and always run the blower prior to starting,might be out of habit or CMA but never had an issue so I'll continue to do so.
