Much thought and some reasoning went into the decision to purchase her knowing that these Gardner workhorses were no longer manufactured. If it was even five years ago I would have made a different decision. But the Internet allowed me the luxury to find replacement parts and the go ahead to find her a new home.

We have finally had another engine part fail. The
starboard engine starter just grinds when run. I removed it form the
engine and sure enough, there is wear on the starter gear and bronze metal
flakes in the flywheel housing. I've contacted Joe Dugan in Ft. Lauderdale
to expect the unit shipped to him this week. Joe worked on Tortuga many
years ago when the first owner was traveling the east coast.

For the past year I have labored over ordering parts for
my Gardner engines. The major problem being that my previous supplier
could not accept credit cards for payment. Just today I have discovered
that Gardner
Parts Limited in Manchester, England will accept VISA. And to
celebrate I ordered all sorts of fun things: a hat, a jacket, a mug, pens, and
most importantly - a pendant to fly from the mast and a plaque which identifies
this boat as powered by Gardner.

A wonderful end result of cleaning up wiring in the engine
room has resulted in the oil pressure and water temperature gauges for both
engines are now working. When we first acquired Tortuga there was single
conductor wire running all around the overhead in the engine room. It was
draped from other wire, wound around piping and just simply hanging around.
Brown and gray wire that looked like extension cord wire was attached to every
possible terminal on the engine sensors and seemed to be running between the two
engines. I took the approach that it couldn't be correct so made the
drastic decision to cut it all out without even tracing where it went. Wow
- all of the sudden the instruments starting working. I'll go back later
and make sure I took the right approach. One interesting draw back to the
engine alarm systems: The alarms sound for both loss of oil pressure and
cooling water over temp. I lost an engine on the trip to Huckins and yet
the alarm did not sound. It turns out that the oil pressure does not drop
below the safe value for almost a minute following engine shut down. I'll
need to pay careful attention to that fact in the future. Right now there
are two distinct LOUD buzzers for the alarms (one for each engine).
However, there is no visual indicator light to alert you immediately to the
failing engine. I'm sure I will add that feature in the months to come.

The task of replacing the Gardner fuel filtration system
has started. I love the twin filters that can be changed underway, but
buying filters is such a problem (ordering them from England). I ordered
the first of the dual Racor 75/500 MAX filter systems today. It will
arrive this week. I'm leaving the Gardner secondary filters (2 micron) in
place. The Racor will use the 20 micron element. Stay tuned for some
before and after pictures. Jan.2002 update - the second filter system has
arrived and is awaiting start of the installation. This will be the next
task on my list after the power distribution task in complete.

The starboard engine blows dark black smoke (actually
suiting water) at any speed above 1100 RPM. (Note 1400 is max) I'm
hoping it's a valve or something less complicated. Fortunately that engine
is the easiest to work on from above since the solon floor lifts above the
engine giving us great access. I'm also experiencing some hesitation at
that RPM so I'm changing fuel filters again this weekend. The port engine
has been a champ!
Repair Work as of August 30, 2001
Getting ready to move one of the floor support struts back
to its original position. For some reason it was moved, but this is a real
problem since the grease gun for injecting into the shaft bearing is mounted on
this strut. It's been disconnected for who knows how long. That
means the shaft seal is probably dry. I can't imagine why it isn't
leaking.
We are currently putting together a wish list for spares. A suggested list from Dave Shaw [shawdiesels@xtra.co.nz] follows. As one can imagine, spares are still to be found in England, Western Canada and New Zealand. I'll put together a complete listing of suppliers as time goes on.
"The inclusion of a gasket set would also be a good idea."
6 x R10076 Injectors $250.00 ea.
2 x Spare fuel lines $50.00 ea
1 x R10145 Water pump (cent) $800.00
6 x L21779 Oil filter $31.80 ea
12 x L21765 Fuel filter $18.54 ea
12 x S05516 Fuel filter * $21.69 ea
4 x L20099 Water hose $26.35 ea
2 x L20098 Water hose $26.47 ea
1 x A04933 * Decarb set (top) $447.59
1 x A04908 * Packing set (complete) $525.85
* Fuel filter primary sometimes supplied ex Gardner Works (Duplex). The gasket set either option is available.

Here is a manual from one of the original Gardner "L" Type diesel engines.
