Lehman 120 Raw water pump

[Andy G]

Well it's about $1.40 a litre, which is about $5.60 a US gallon, approx.

John P and Daddyo,

You were right.* There was not much to installing the new water pump.* The only complication was rerouting the raw water supply line just a bit, requiring a new threaded fitting with a barb.

Pictures below...

Thanks for the encouragement!

Good Job,* How much was the new Pump$.* If you still have the original drive, you can list it in the classified section.* Someone might want it as a spare.*Folks still with the Jabsco can lose cooling at any time if the drive fails. A spare drive can get a single engine boater back to their homeport for repairs.

Good job Wannabe!

JohnP,

The total cost was about $500.* Pump supplied by American Deisel along with some great guidance.* They are the best!

Looking at your photos of the new pump installed -

One thing I dont care for is a hose connection in which the hose HANGS from the hose barb fitting. Rather, I like to see an 90 deg elbow then the hose barb so the hose comes on horizontally instead of vertically.

In this way, the hose is not pulling itself off by gravity.

I know its a nit pick. But if your clamps ever get loose, the vertical installation has a higher possibility of catostrophic failure than a loose clamp on an elbow installation.

Don't agree about adding another 90degree elbow into the system.

But,* I probably would have painted the whole thing red before installing.

Nit pick 2************ JohnP

Nice job with the replacement.* I had the same problem, and also replaced with the new unit, as supplied by American Diesel.* Easy install.* And.....I've yet to paint mine red.

 

[MVDarlin]

American Diesel has a number of recomnened easy changes to improve cooling and oil pressure. Give Brian a call to discuss.

So, how would a hose clamp become loose? Perhaps you have some insight that might help those who have no choice about the orientation of their elbows.
