Fatal water pump error

[funsailthekeys]

When installing a routine raw water pump on a Perkins 4-108 it stopped working less than an hour later. Turns out that when doing this you need to rent a special alignment tool from Perkins to properly line up the new pump on the adapter plate. The coupler on the new pump ($465.00) shattered. I called Jabsco and they will repair it for $63.00 and labor. The tool rental is $45.00 with a $100.00 deposit. The things you learn.

It would be nice if they told you that when you bought the pump.

Also, be very careful when mounting the pump to use the correct gaskets in front of and behind the spacer plate. THEY ARE NOT IDENTICAL! Using the wrong one(s) can block the water ports and cause overheating.

Sometimes ya gotta wonder what was on the minds of the engineers and designers that designed a thing like this.

I trust there will be a tool rental barge 400 miles offshore?

I want one.

And what's on the minds of people who sell them... Money, money, money.

From what I've seen over the years the boating industry from builders to suppliers of gear and services have a specific sound for a motto.

CHACHING!

This is one reason why I think that engineers who design something as complex as an engine should be forced to work on them as service techs for a year, with only the basic tools available to the average user. It would be the cause of much more intelligent design in cars, boats, etc.

sailingdog you are right on in your comment ! over the years i have thought about this many times. common sense seems to be lacking in many designs.
