Re: Stus-List Proper Blower Installation - 30 mki

[Robert Boyer via CnC-List]

I have a full cockpit enclosure on s/v Rainy Days.  When motoring with the 
enclosure in place, the engine's intake air must come from within the 
enclosure, reducing the oxygen content in the enclosure.  I have a new blower 
but the intake and exit are presently inside the enclosure.  I have to modify 
my enclosure so that its not this way.   So, if you ever plan on adding a full 
cockpit enclosure, you have to pay attention to where the engine's intake air 
is coming from...

Sometimes its nothing you did.  My theory is that besides changing galvanic 
properties of underwater metals, like prop, nut, shaft shark, at a worst case  
boat wiring deteriorates over time.  This could result in more stray current.  
Current not going back to negative of the bank, but instead leaving via prop 
shaft and your zinc.   Obviously very small amount, but enough over a season to 
notice deeper deterioration.

Re: Stus-List Proper Blower Installation - 30 mki

[Della Barba, Joe via CnC-List]

I suspect that C&C decided to just put blowers everywhere and then not have to 
worry about what kind of engine got installed. Also diesel engines can be 
smelly and maybe they thought it was nice to have a way to pull the fumes out. 
I have never ever heard of a diesel leak causing an explosion, but many a boat 
has burned when a fuel leak encountered a red-hot turbo, Prior to turbochargers 
being water cooled this was a cause of numerous fires.
BTW – there is no way a diesel engine can reduce the oxygen in your boat 
without reducing the air pressure in general. If your enclosure is tight enough 
to hold vacuum it is way better than most!

My blower (pulling stale air out) and comes on automatically with the ignition. 
  Serves two purposes;

Diesels loves lots O'air in addition to clean fuel Keeps air temperature in 
cockpit locker temperate where the refrigerator compressor resides.  More 
efficient. Eliminates the human factor in it being on for #'s 1 & 2

Re: Stus-List Proper Blower Installation - 30 mki

[Patrick Davin via CnC-List]

Interesting. We have a full cockpit enclosure too, but it doesn't cover the
two stern dorades (they're outside the enclosure) which I presume feed
engine air pretty well (they're above where the old blower was).  Our
enclosure also is nowhere near air tight - lots of air comes in / leaves
through the open corners and bottom edges. But diesels could consume a lot
of air so with a really air tight enclosure also enclosing the dorades I
could see the need for a blower.

Re: Stus-List Proper Blower Installation - 30 mki

[Patrick Davin via CnC-List]

Diesel doesn't vaporize easily, unlike gasoline. That's one of its big
advantages on boats, that it's non-volatile. It's good practice to shut
down the engine at the fuel dock anyway, but they're probably asking that
more as a general policy due to the gasoline boats they fill (or in case
some gasoline vapors wafted over to your boat).

The flash point (vaporization temp) of diesel is 126 F:
https://en.wikipedia.org/wiki/Flash_point#Examples

There's a good writeup on engine blowers here:

Stus-List Diesel ventilation

[Charlie Nelson via CnC-List]

I had my Yanmar 30GM replaced about 10 years ago with a Beta-28--it fit 
physically and was the proper power for my 36XL.


The yard did a really good job of sound insulating the engine compartment with 
the plastic lined 1/2 inch foam--previously
there was no insulation.


A year or 2 later I replaced my AC unit and removed the ductwork which 
previously delivered air under the nav station for the main and forward 
cabins. I left the vent cover in place to cover the hole left behind when I 
ripped out the flexible ductwork.


Since then, I have noticed a build-up of what looks like a layer of greasy soot 
on the fiberglass under the nav station.


All the recent comments about diesel ventilation got me to thinking that maybe 
this soot is from the engine, which has 
the usual exhaust system. Further, I never smell exhaust down below but this 
soot returns after cleaning--not immediately
but after a few months of light use, going out and in from the race course.


The engine never seems starved for air and of course the bilge is open to the 
engine as are pathways via the
aft cockpit lockers, etc.


I can't see how sucking air in thru these vents
would bring the oily soot with it. OTOH, I don't see how or why the engine 
would force engine room air out this vent. AFAIK, the
air for combustion gets into the compartment from normal openings via the bilge 
and the aft lockers, none of which are close
to air-tight.


I have never noticed any air flow near this vent during operation--if there is 
any it is pretty light.


Any thoughts on what might cause this?

Re: Stus-List Diesel ventilation

[Charlie Nelson via CnC-List]

Not near it but it could be the culprit. The belt has sometimes run a little 
loose allowing
it to rub against something nearby (I forget which) which released a ton of 
local
belt dust before I replaced it and tightened it.


Plus the fan on the alternator housing could provide a positive pressure to 
force air out
of the compartment.


Now that the belt has been replaced and tightened properly, and the soot
cleaned off of everything I could reach on the engine, the problem might be 
gone.


It could be the source of the problem and it just landed mostly near the vent 
on top of the white fiberglass.


This list never ceases to amaze!


Thanks,


Charlie Nelson

Re: Stus-List Zinc decay

[David Knecht via CnC-List]

I was on shore power for the C&C Rendesvous in Clinton, CT.  I don’t think I 
have a galvanic isolator.  I have looked at the pictures and don’t think I have 
seen anything like it. Where would it be installed?  Dave

David,

Most likely in the port access hatch next to the helm seat (near the shore 
power connection outlet)


All the best,

Edd

Re: Stus-List Diesel ventilation

[Marek Dziedzic via CnC-List]

My thought exactly. The belt(belts) will create a soot-like powder that covers 
anything around the front of the engine. The best prevention is to have the 
proper tension on the belts, but even then they might slip.

Btw. Many(most?) diesels have the vents built in (with blower fans), but most 
people use them mainly to keep the temperature down in the engine compartments 
(and consequently in the cabin). As a bonus you reduce the potential smell.

I have the blower on all the time when the ignition key is in the ON position. 
However, some people don’t like the idea as the blowers are not, supposedly, 
designed for prolonged operation.

Is the vent cover near the new engines fan/alternator belt?

Calypso’s Perk 4-108 belts kick off a dust/soot like debris that gathers on the 
nearby sound insulation.

It will be installed on the shore power ground wire somewhere between the
inlet receptacle to the breaker panel.
