Update:

Looking at the owner manual, I just saw the engine, in addition to the intake fan, has also an extraction fan FASCO 24 Volt 2807-513-122 --- 93004-2815
http://nikimat.com/engine_room_fans.html

Engine on, I noted it was not working and likely the cause of the warmer engine room.

With a Volt Meter I checked current was going to it and it did: measured 13 Volt.
It seems normal as the owner manual says so…

Does someone know why this “24 Volt” FASCO 2807-513-122 --- 93004-2815 is connected to a 12 volt connection?

Olivier?
Joel?
Bill? Anyone?

Good morning,

May be I am a control freak, but when using the engine or
genset I monitor the temperature of the engine compartment
via a wireless temperature sensor. 

I rarely use the engine for more than an hour at the time
(mostly to leave and come back to a marina), but in a few
occasions had to motor for 10 or more hours.
The temperature in the engine room, will gradually increase;
when it reaches 47*C I open the engine hatch (sea condition
permitting obviously) for 1/2 hour to cool it down to 45*C
and so on. 
“My” reason to do this is because of component from the
generator melting at 50*C. 

Note:  the “suction” (intake) 24 Volt Jabsco
35440-0010 250 CFM Blower Fan is working (starts when engine
is ON). 

Is there may be an air intake our outtake that could be
partially blocked? 
Is there another fan I am forgetting about? 


Other note: when using the Generator, it rarely goes over
46*C after 2.5 hour use (its fan is also working).
