You mean cool down yourself and your crew, if I understand correctly?
I'm asking because, just for the records, I've seen that in my boat the e/r temperature gets actually higher, at D speed.
I never bothered checking the exact temperature, but I'm sure of that because there is a double thermostatic control of blowers: one is set at 45 deg, and is active while the engines are running, and the second is set at 50 deg, and becomes active after the engines are turned off. The logic is that obviously after turning the engines off, the air exchange inside the e/r becomes close to nothing.
Now, the interesting thing is that while cruising at 1700/1800 rpm, the e/r temp never reached 45 deg so far, because I've never seen the blower going on automatically. But in a few occasions when I cruised for a while at D speed, the blower did start automatically...
Yes cool the people down , get a breeze .
Tbo never really thought about ER temps .
I guess @ 825 rpm they pull a heck of a lot LESS air in than 1825 rpm .
Water temps drops to 81 from 84 and EGTs go under 300 from N of 560 .
Dunno about actual air temp of the ER .We have no blowers at all .
Anyhow glad to hear you seem to be adjusting happily to P speeds ,trip seems to be going well .:encouragement:
