{Stus-List} "Cheaping it" - OEM parts

 re NAPA

    Aftermarket autoparts rarely last anywhere near as long as the OEM. Even
things as seemingly simple as exhaust pipe or brake lines rot out in no
    Sometimes however, either when OEM parts are available from various
suppliers, or when only aftermarket replacements are available, considerable
savings can be had by shopping around.  Last year a customer at the marina
where I dock my boat ordered a set of injectors through the marina from a
marine supplier. He was later advised that the same parts were in stock at a
local farm supply, so he went and bought one to do a comparison. When the
injectors from the marine supplier came in, they were identical to the one
from the farm supply. Same manufacturer (NGK), same markings, same
everything except almost 4 times more expensive from the marine supplier. I
am not sure now about which make and model of engine was involved, but I
will find out if asked. Many marine engines share common parts with their
terrestrial equivalents, but where the parts differ, there is a reason.

I (used to belong) was associated with a yacht club that maintained their
launch ( a Tripp launch with a westerbeak ) using the all too affordable
NAPA auto parts- no slight to NAPA- they make fine parts or cars- and most
holiday weekends, sunday evenings, the launch was out of service...the most
frequent cause?  failure of NAPA electrical parts, starters, and other auto
grade repairs.  What is more expensive than a YC where the launch does not
run...since the club is located on the shore of a usually choppy river with
lots of (high speed) motorboat and ferry traffic, strong currents and tides,
a beach launched dingy and 1/2 mile row just did not suit the attitudes- or
the physical abilities of most members ad their wives.

Far as I can tell, they repeat history year after year...somehow expecting a
different outcome.

The lesson- as this thread suggests- don't go cheap (different than thrifty)
on maintaining a sailboat

 As a guy who is around boats, works on boats and generally just likes
"messing about with boats", I see a lot of less than optimum decisions made
by boat owners, including me.

OK, me first.

On the trip from Mandeville to Pensacola, the engine oil pressure reading
began to increase, finally pegging out at over 100 psi.  I figured it was a
bad sending unit or secondly a bad gauge.  Provisionally I decided to do an
oil change and filter change and anchored and did so noting nothing
abnormal.  When I got to Pensacola, I located a Westerbeke distributor and
found out a sending unit was $70+.  I couldn't find the resistance
specifications for it to locate a "universal" unit.  Heck, a sending unit is
a sending unit, right?  Being in a particularly unusual "cheap" mood, I went
to a local auto parts store and got a 0-100 psi sending unit with the
correct thread size and installed it.  The gauge still pegged out.  $15
bucks down the drain.  I called my buddy in Mandeville and ordered a new OEM
gauge and sending unit.  Installed the new sending unit and gauge this
weekend and the readings are normal again.  It was the sending unit.  I kept
the old gauge as a spare.

A few weeks ago, my 2nd "cheapie" air conditioner cooling water pump died.
This $50-60 pump came with the original air conditioner.  I installed my
spare "cheapie" pump (the 3rd pump in 7 years).   I just never upgraded and
always carried a spare.  Now I'm upgrading to a $250 Dometic pump which
should have much more longevity.  I will keep the 3rd "cheapie" as a spare.

My buddy called me tonight to tell me about a boat having electrical issues.
In particular, the refrigeration system wasn't operating properly.  On
investigation, the owner had replaced the two 4D house batteries with a
couple of much smaller series dual purpose batteries.  Heck, batteries are
batteries, right?  The owner wasn't happy with having to pay my buddy a
couple hours labor to tell him he's a dumbass and he should go buy some 4D
batteries.  (Well, I'm sure he said it more tactfully.)

I had that same discussion with one of my clients.  He wanted to do the same
thing.  I told him that not only would he adversely affect the electrical
system on his boat but that he would decrease the boat's value.
Fortunately, he listened.

Point:  every time you "cheap" something, you pay twice, once for the cheap
shot and then again for the right way.

I could go on and on.  It's a lesson we never seem to learn.

Sorry for the rant.  I just hope it prevents someone from paying a little
bit now and then a lot later.

Anybody else want to share similar experiences?
