More inferior Hatteras components

[Briankinley2004]

Here is another example, to add to recent ones, about how Hatteras and their suppliers cut corners and used inferior components in the construction of their boats back in the 80's. My starboard bilge blower started tripping the breaker and I determined there was a dead short in the motor. Pulled it off and the squirrel cage plastic blower fell out in pieces, obviously a victim of pre-mature degradation from engine room heat. When I removed the hoses the label indicated it was manufactured in June of 1982. It is totally unacceptable for one of these simple products to only last 41 years in a marine environment. I checked the port one and while it is running it is not putting out much air. Im sure it is falling apart as well. The Chinese ones that will be replacing these will outperform them by getting at least 1/20th the life span.

Now that's funny

The sarcasm is strong by the OP.

All of mine fell apart too. I feel your pain. Lol.

 

[brettportzer]

Same from ‘72!

Just in case you are looking for the parts to replace them this is what I bought through West Marine.

From the sales ad;
These Jabsco blowers are primarily intended for intermittent duty cycles such as evacuating fuel vapors from bilge areas. If desired, they also may be used for other general air circulation applications with longer duty cycles. However, when doing so, it should be noted that the maximum motor life is approximately 1000 hours. Therefore, the blower should only be used for applications if this length of service is acceptable.

Sadly, the 32Vdc continuous duty blower motor is not available any more.
The 24Vdc continuous duty blower motor is.

Mine from 1971 still work.

But the engine room light switch finally quit working after 52 years. Only 52 years. I expected more.

No warranty !?

I had to replace the crappy water heater they put in that was 40 years old. I hope I can get 10 years out of the new one.

Not that I've been able to find...

Same with our dishwasher. Damn seal started to leak, very disappointed. Truth is I’m sure I could have fixed it but the digital panel had a big chip in it and was not replaceable so I used the opportunity to replace it with a new SS model.

I replaced the blower on Pau Hana in the V-berth for the AC with a new one from Amazon. I had priced it from Grainger and then was able to search it on Amazon using the Grainger catalog number... then the AC compressor died completely, so I had to install a new unit.

Well poor quality struck me too and my 43 year old 32V blower gave way. Does anyone know of a good source for the 32V flex plate blower. I can find 12V and 24V but no one seems to have 32V.

Sams has them but they aint cheap

Sadly the 32Vdc continuous blower motors are now, not available at all.
We replaced our 15+ year old normal cycle (thematically controlled) 32v blowers with 24v continuous blowers using a 24V tap off of the stb 32v bank.

When I autopsied the 32v motors, one brush was worn aweigh in each motor. I used good brushes from other junk motors (same brush for 12, 24, 32 motors) and now have 32v motors as spares for the other blowers and sump pumps. But these are still not considered continuous duty.

Also, 15+ year old plastic blower fans were brittle, along with rusted out case screws and more rebuild issues. Yep, easier to replace the whole blower sometimes.

On blowers, shop for continuous operation type motors and update your ships manual that they are installed & where used.

 

[krush]

How about grab a 24volt blower and use a PWM controller to drop the 32 to 24nominal?

 

[johnjen50]

There is another thread on the blower fans. I just bought a 36 volt one last year and it works fine but I can’t remember where from, but it was a company in that thread I think. Just about a direct replacement dimensionally as well. I will look to see if I have the name of the company.

I like the idea of using a step down and getting a 24V blower motor. Is there any downside to this approach that would justify the incremental $500ish dollar cost to replace 32V?

I think the only disadvantage would be how long will the step down electronics work for?
Anything new electronics likely won't last too long. Made in China "work good for you one time"!
