1999 Hunter 380 Blower location

[wojo5901]

My blower was working last year. I can hear it. Now I can't. Looked for it but could not find it. I thought it was in the engine compartment, but it's not. Any advice on the location of this blower on this boat, would help. I purchased this boat 2 years ago and it must be in a location I have not looked. I read through the forums that are posted, nothing is quiet helping.
thanks,
Mark

Welcome to the site.

This is an after market install. Hunter did not install blowers in 1999.

You're going to have to your homework on this one. Look for an exhaust vent on the exterior of your boat such as this one I installed :

You are looking for hose about 3" OD :

Rest assured, the blower will not be in any place that is easily accessible.

Check the connections at the switch and the fuse.

If you have an on board Generator, the Blower may be there.

My blower is located there.

Thank you all, I will look further when I get back to the boat. Hopefully this weekend....

Long shot reopening an old thread .... did you ever locate the blower?

I have a 380, without a generator. I'm looking at options to cool the engine compartment. I don't really want to put more holes in the crossmember that are under the aft bunk, seems like that would weaken the hull? I guess another option is to pull air in instead of pushing it out, but if it gets pressurized that will just heat up the cabin in the summer....

Still deciding if this is a worthwhile project. My alternator runs at about 75 deg C. My hopes is that pulling hot air out would help cool things a little.

Somewhat unusual. How do you supply power to your battery which in turn supplies power to every little electronic device on your boat ? Never mind that, where do you get enough power to start your engine after you've shut it down while away from the dock.

Lets just say you meant to say "with" a generator.

More like demolish the hull. Not a good idea.

I guess another option is to pull air in instead of pushing it out,

Under no circumstance whatsoever would you ever pressurize a typical engine compartment. It results in expelling belt dust and quite possibly CO from hidden exhaust leaks into your cabin.

An exhaust leak like the one above, could really ruin your weekend if not worse.

See post #2.

I do have an alternator (and solar, and inverter/charger)!

Some H380 came from the factory with 5-8 kW AC generator in one of the aft lazarettes. The boat is pre-wired for a blower in that location, but not in the engine compartment.

I realize that the suction of the engine under load is displacing a lot of heat (about 35 CFM), just trying to figure out if there are simple ways to keep that compartment cooler. Especially for summer cruising, the engine is next to the aft birth and the heat can radiate for 5-6 hrs after use. A blower (suction) would add 100-150 CFM of cool air...

Mine does not need a blower, since my 50HP pulls in Air to run and that is exhaust is water quenched.
My engine compartment is insulated.

My Genset does have a wired Blower, guess why?

PS: it is Heat Balance.

This could be your lucky day.

Depending on how large the volume of this "location" is, you may be able to install a sizeable exhaust fan and remove large volumes of air from your engine compartment and do some major cooling.

In my case and most likely others, you're limited to installing an in-line fan :

which has has smaller volumetric throughput than a larger centrifugal type fan :

There are many centrifugal fans available, it's just a case of finding one with a hose compatible inlet and outlet that runs on 12VDC and fits you available space.

I'm with you @marcham - I've also been trying to figure out how to actively draw air out of the engine compartment to help cool the alt and reduce 'engine smell' - the h380 design is not conducive to this. My boat is wrapped up for the winter and is a couple of hours away, but that issue is on my list to try and come up with a good solution for next year.
