Until 2004, these had only 2 lip seals and the slinger was an O ring on the
shaft. If the pump started dry, it would overheat (It burned the paint off
my cover) and destroy the impellor and seal. Also, any seal leak causes the
bearings to fail as it quickly corrodes the cage that holds the b
There is already a 1" gap, but the pressured water gets across.

Very sorry for your loss. Especially sad that Bucky died even though

Hi all,
Thank you for all the advice and help on my engine issue. Just a quick note to
say that I believe it to be resolved. We were towed in (we have TowBoat US full
membership) primarily because a strong north wind and cold front was coming in
and our anchorage was very unprotected from the N
Ahoy Jim,
Your new boat sounds like a large antique wooden motorboat. You will need
all the help you can get.
A friend of mine had a pre-WW2 Trumpy 86' wooden motorsailer and it ended
up killing him. He got heat prostration working on the planking in the
summer in Florida, was taken to the l
Since you are overhauling the pump, consider installing a "slinger" on the
pump shaft.
This is a thick rubber washer tight around the shaft between the water and
the oil seals to sling any leaking water off the shaft before it gets to
the oil seal.
Also, as I have done on my genset, put some ma
There should be a special place in Hell where design engineers have to live

To quote my brother, who is an engineer working primarily in
engineering design of vibration damping boxes for aircraft
electronics, there is an old saying:
"You finally have to shoot the engineers and go into production".
I imagine there is a fine line there between 'not good enough' and
'over e
To be fair, it's not just engineers. Recall that Van Gough's brother had
to almost rip the paintings out of Vincent's hands to get them to market.

Yes, the engineers (or painters) are never satisfied [I know, I *am* one]
The *MANAGER* has to clearly define *what is good enough* and stop
work once that point is reached.
Martin Fowler et al's series on XP (eXtreme Programming - which is not
extreme at all) is a good read an applicable to many

As my old chief engineer often said, if you give us a year and $100K
(1960s time frame), we can probably tell you whether we can solve the
problem.
