3870 engine room blower

[PortHoleDiver]

Guys, I am trying to find my engine room blower. Even though I have the Hino 700’s I know when I bought the boat the blower would work from the center dc panel. Since then, 2008 the blower quit working and I am trying to replace and can’t seem to find it. Any ideas. Thanks.

You are going to love this. Look under the bar sink and there’s a piece of plywood that is probably carpeted at the back of the cabinet. That piece of plywood goes all the way to the helm cabinet and is attached at the top and bottom with screws. If you are groaning at this point, you’re right. You may be able to get to the blowers by removing the forward side grill, but I’m not sure. We found our blowers, or what remained of them, as we were replacing the carpet with teak and holly plywood and had removed the bar.

Thanks for the reply. Wish I had known this 6 months ago. I just replaced all the carpet in the boat but did not remove the bar. We changed the bar sink and faucet and carpet inside the bar too. Ugh! I will have to get in there and check it out. Much appreciated cause I sure couldn’t find them before.

I replaced mine (there are two) by removing the forward starboard grille then working from below, in the engine room, on the starboard side of the starboard engine looking upward. Not exactly easy to get to but I was able to do it.

Thanks, Jim. Do you know if they were 4" or 3" blowers?

[Jim_Gandee]

4” blowers.

On our 38 they are 4" Attwood blowers. They come in two styles, one has a rubber cover on the wiring.

Yep, 4” blowers.

just curious, what is the purpose of a blower on a diesel boat?

[MacPhid]

Blowers help cool the engine room after shut down, plus a lot of east coast (especially) were fitted with gas engines. That said, with our diesels we don't run the blowers before startup, and only occasionally if I need to be in the engine room after a run.
