Noting that the coolant flow is from left to right, and that the impeller direction in this view is CCW due to the impeller assembly being turned inside out for the picture. When assembled it rotates CW same as the engine rotation.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8016384623154744405.post-39835199599275976092011-03-29T09:43:48.173-05:002011-03-29T09:43:48.173-05:00No, Randy's impeller is correctly installed as...No, Randy's impeller is correctly installed as shown in the picture.<br />Contact me for further discussion.<br />rick10@tds.netAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8016384623154744405.post-67319778837415891012011-03-06T01:25:14.412-06:002011-03-06T01:25:14.412-06:00If you are not comfortable with taking these measu...If you are not comfortable with taking these measurements, you can always purchase a water fountain kit that contains all the necessary parts that are guaranteed to work properly with one another.

Especially the comment of anonymous explaining how the water pump works. The explanation is accurate and to my opinion correct, it also contradicts the last picture of Randy's photo session: the flanges of the impeller point in the wrong direction!!Unknownhttps://www.blogger.com/profile/08506244313223627277noreply@blogger.comtag:blogger.com,1999:blog-8016384623154744405.post-43596110057521200492010-05-24T17:58:00.348-05:002010-05-24T17:58:00.348-05:00No one has mentioned retaining or replacing the ke...No one has mentioned retaining or replacing the key on the shaft?Unknownhttps://www.blogger.com/profile/17568696729954187082noreply@blogger.comtag:blogger.com,1999:blog-8016384623154744405.post-10147615933112634722010-05-21T12:39:03.076-05:002010-05-21T12:39:03.076-05:00Hello

Understand how it works once, and for the rest of your life you will never curse yourself for forgetting to mark the direction of rotation. Here is how it works: it squeezes water out before approaching the narrowing (where the segment is welded inside the cylinder) and expands, sucking water, when exiting the narrowing. The intake is where it sucks, the exit is where it squeezes. Since you know for sure where the water comes from (seacock) and where it goes (engine) you can figure out which direction the wheel rotates).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8016384623154744405.post-23283352608076188702009-05-09T03:27:00.000-05:002009-05-09T03:27:00.000-05:00Yes, you should always close your seacock before t...Yes, you should always close your seacock before this procedure. I think it's important to mention this also, especially if you own an older boat: go through every seacock on your boat at least twice a year and open and close them several times. They have a tendency to freeze over time, and I've had them literally break off in my hand at the worst possible times.Dave Guilfordhttps://www.blogger.com/profile/03833838302093060042noreply@blogger.comtag:blogger.com,1999:blog-8016384623154744405.post-63312864019631176362009-05-08T21:00:00.000-05:002009-05-08T21:00:00.000-05:00I've seen instructions for this process in a coupl...I've seen instructions for this process in a couple of places and both have advised to close the raw water valve prior to the procedure.

A little waterproof grease on the gasket may improve the seal. Worth changing annually, though my impeller shows little wear at the end of the year, as this is not an easy job at sea when you may be relying on your engine - else why is it on??Anonymousnoreply@blogger.com
