Oh goodie!  We get to go down into the engine room again and learn something new.  Today we are going to learn how to change raw water impellers on our Volvos (that is the engine in case you forgot:)).  The purpose of an impeller is to circulate the sea water thru the heat exchanger (which is basically like a radiator in a car), then the water goes thru the tranny (transmission) cooler and finally it exits thru the exhaust, which also get cooled by the water.  Sooo, if your impeller goes out, as in there are only 3 blades left on it, there will be a lot of items in your engine that will be overheating.  That will not be good :(.  So lets go to the “From the Engine Room” page and we’ll find out how it is done.

For those of you how could give a hoot about how to change the raw water impellers, here are some pretty cob webs from the other day when there was heavy fog at the marina.   Pretty huh?  Even though they poop on your boat and leave little black spots, they can sure make some incredible things, can’t they?

Next time we’ll be covering changing your zincs.  I can hardly wait!

Until then TTFN!
