Engine Room Cooling Fan

[witeagle]

Ok - here it is finally....

Inside of the Starboard Bench Seat, the forward part of the storage area has a box screwed in (appears factory). Under the box is the fan you see pictured which is from Delta T Systems (http://www.deltatsystems.com/) who focus on engine room venting systems. The fan is an 11" axial fan rated for 1700 CFMs. The new model they sell is only rated at 1424 CFM, however it is still a lot of fresh air being pumped into the engine room.

There is an intake cowl on the forward bench seat to intake the fresh air and force it into the engine room.

The fan is wired from a helm mounted circuit breaker to a soleniod under the helm station which is triggered by the starboard ignition switch. It's also wired through the sea fire engine cutoff so in the event of a fire, the fan would also cut out and shut down the oxygen flow to the engine room.

By the way, the fan cost about $200 and could a box similar to the OEM box could be built. I would think a retrofit with fan and all the parts to put one in would run about 350 to 400.

Any questions - let me know.

thanks wit. i have seen countless 32s over the years from 1994s through 2007 and i have never seen that setup. remind me what motors you have?

we dont seem to have any negative air pressure in the engine room with just the hull vents and our cats are at 350hp....i wonder why the need to add add'l venting was done to your boat....maybe operating down south in hotter temps? I m guessing this was retrofitted by the previous owner...I have never heard of Delta T doing any OEM work from Luhrs but who knows, anything is possible.

I have CAT 3116's at 300 HP.

My boat was originally in Florida and brought up to Maryland and then I brought it to NJ, so the fan may have been added to deal with the extra heat down south.

The fan was installed OEM because it's in my wire diagram in the owners manual.

By the way, an employee of Luhrs has been selling off some old parts on EBAY from the Florida plant that they didn't move to NJ. She is/was selling a 12v and a 24v model of this fan.

yeah i forgot you said that it was in the wiring diagram....do you have the blowers mounted on the pads by the side air intakes too??

There is only a blower mounted on the port side. I was suprised that there was only 1 blower, unless someone removed the other one. Although I have no clue how they would even get to it since you can't really get outbound of the starboard engine.

sure you can get outboard to starboard. remove the coolant expansion tank and go over the top of the cat....i fit (6'1", 175lbs) and my brother fits (5'9", 170lbs)....

I don't fit (yet) - 5'8 and down to 210 (from 260)
