[C38] Heat exchange

[Chapuys at aol.com]

I have almost finished installing the new heat exchanger on "Bolero" in San 
 Diego.  Just made my third run to the marine hardware store.  I will  let 
you know how it works out.  I should probably go the whole 9 yards  and 
replace the impeller and the thermostat too.

So I"ve been reading all the info about heat exchangers and feeling prety  
smug as everything looks good on Impulse. I was going to change the oil  
yesterday and started the engine to warm things up, poking around as a good  
obsessive compulsive will I noticed a small leak where the rubber outflow hose 
 connects to the heat exchanger. Ok you guessed it one little wiggle and 
there  I was holding a rotted off  piece and muttering curses, while at the 
same  time giving thanks for this site and all the info. available here. Of 
course  we were planing one more trip however it will suffer only minamal 
delay thanx  to this site.
 I noticed I think it was Steve mentioning 6 knots at 1800 rpm I run  at 
2200 most of the ti9me what prop do you use?
