[C38] Heat exchange

[Steve Smolinske]

lol I did, funny how one thing leads to another, I also replaced the fresh and raw water pumps.  I tried rebuilding the raw water, but even with new seals and a new shaft it still leaked.  I decided after reading Tom's post about sealed bearings in the fresh water pump that if I didnt replace it it would go out on a future trip.  Good news is now I have a spare water pump on the boat.

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?
