Fresh air hose question.

[TacomaCouple]

Ok, so today I started all my projects on the boat. I started off taking pics to see what I needed to do and explored the boat a lot better than I had before. I found a few things out that I had had questions about, like:

I do have a proper anchor with chain and line.

The inverter I have has pleg in's for things.

The back end can lift up...didn't know that.

I found the bilge pump below the motor.

I also found something, by taking pics, that I have a question about. The vent that has the fan on it to get rid of the motor fumes has a cover on it that the dryer hose thingy hooks up to but the intake vent on the other side doesn't.

I was told I need a hose from the intake vent down to around the motor area. So I need to find a cover for that vent, obviously, so I can run a hose down to the motor area, right?

See the pics below that show the vent cover taking the bad air from the motor and the pic I took, today of the intake vent that has no Black back cover to hook a hose up to.

What do you think?

Does the vent on the right allow air straight into the Engine bay?
If so that should be suffice.
It's hard to tell on the picture on the left but if that is the blower hose exhausting the engine bay and it works then you should be good. Double check with it on and feel to see that the blower is venting out not sucking in. I've seen people reverse them either by accident or thinking they're redneck super-charging their engine.

Yes, the one with the blower is venting out, so it should be good? The other one has direct access for air to flow to the engine area. So that should be good as well?

One project done!!! We plan to be playing on the Tacoma area of the Sound all day Friday!!!! Yeah!!

Sounds good, no pun intended

I am no expert on theses things by any means but mine does not have a hose on the port side where the air comes in. I have two vents and the way I understand it, it draws fresh air on port and exhausts starboard. The way I understood it was that this was standardized. So there should not be a need for an intakae air hose necessarily. For whatever it is worth I had the same question not too long ago and that was what i found.

Most will have a second vent tube that only draws fresh air in to replace the bad air being blown out. It'll work either way, but with a second hose, you're feeding replacement air directly to the affected bilge area.

Otherwise, it's competing for air flow from everywhere else in the bilge. Which might not be fresh. It just helps to get maximum fresh air to that potentially flammable area.

My boat has an inlet louvered vent on the starboard and port sides. Each side has a black plastic "box" just inside the louver that facilitates dryer vent hose attachment. Also, the black plastic box is tilted slightly so if water splashed in the louver, it probably will run back out rather than into the bilge. There are two clam shell discharge vents on the top of the stern. The bilge exhaust fan is attached inline to one of the dryer hoses that connects to a clamshell. The exhaust fan really produces good airflow.

Right after I purchased my boat, I installed a bilge sniffer. The sensor is located very low in the bilge just in front of the engine. Although I always blow my bilge before starting, I like the idea of having a sniffer. It is very sensitive and is alittle extra insurance if something regarding fuel distribution occurred while underway.

Yeah... a sniffer is something I don't have yet. Nice upgrade, especially for piece of mind.
