Blower for Diesel
I've got a Ranger 33 with a Universal 4-30 diesel. I recently bought the boat in October and was aware at the time that the blower didn't work. I was also aware of some electrical problems. While cleaning up under the cockpit I came across the old blower which was mounted just under one of the cow vents. Suffice it to say, it was very rusted out. Tracing the wiring, I came to realize that this was the cause of the electrical problems. No fuse and the motor rusted out, shorting and causing excess heat...melting some of the wires.
Anyway, I've removed and cleaned the wiring up, replacing as needed. I've read that blowers for diesels are good to improve reliability. I've read that the blower needs to "pull" air out of the compartment. The question I have is how should I mount the blower? I have two cow vents. It seems to be they are a potential entrance point for water either from rain or waves from the aft. Should I put a blower on both vent? I read about putting a filter at the input of the compartment to prevent water, salt and other contaminents from getting into the engine compartment. Anybody have any good information for the creation of this? Any good links?
