That’s Stanadyne.

 

Recommended as a stabilizer for long term fuel storage (up to 2 years or so) by 
both Yanmar and Cummins (the two diesel engines used in Hyster & Yale lift 
trucks) at the time I retired. 

 

Stanadyne (though I don’t recall exactly which specific additive) was also 
recommended as a lubricity enhancer by these two brands for diesel engines made 
before the change to Ultra Low Sulphur diesel (500 PPM to 15PPM) which happened 
about 2008 or so depending on which country you are in and when various 
emissions tiers were effective.

Chuck,

I too am a LanaCote user but mostly for turnbuckles and rigging terminations 
that could harbor water.  I have a 20+ year old container of LanaCote that I 
usually heat up a little to reduce viscosity before applying.  That stuff is 
almost un-usable when cold.  I was able to easily disassemble Calypso’s 
turnbuckles when rebuilding the deck near the chainplates.

I would not hesitate to use LanaCote on fasteners if I ran out of Tefgel or 
more likely, could not find the Tefgel syringe.

Yes.  Screws coated with Lanacote come right out.

Maybe I'm the only lister using Lanacote?  All the other list comments seem to 
prefer TefGel.  I bought some of that, but when I had to choose, I chose 
Lanacote because of past experiences.  I can't say LanaCote is better than Tef 
Gel, cause I never did a test comparison, but a little goes a long way.

Around about 2007, I repainted my boom.  I removed all the fittings on my boom 
and sanded to bare metal, primed with etching primer, and painted it.  I used 
Lanacote on all the SS screws holding straps and blocks, etc.  In 2019, I 
decided to install Lazy Jacks and removed all the fittings to repaint the boom 
again.  It's simply a waxy lanolin and I like it.  I installed all the new SS 
fasteners using the same tub of Lanacote I purchased over eighteen years ago.  
It's good stuff.

It's not possible to just slide out the hatch acrylic since the fiberglass

it, but don't want to do that). I have a photo I’ll try to attach below.


The reason we need to pull the hatch is that there seems to be something jammed 
in the track slide - sometimes when we try to slide open the hatch it jams on a 
screw or something loose in the track, which I can't see or recover.

The fiberglass cover is also due for resealing anyway, as it leaks in some

This looks like a big job, just wondering if anyone else has done it and has

Joel,

This applies to any engine that is fresh water cooled (i.e., has two cooling 
circuits - the "internal" one that uses the coolant and generally works the 
same as in your car, and the "external" one that uses the outboard water for 
removing the heat from the engine). The heat exchanger, as the name implies, is 
a place where the heat is exchanged between the two systems. It acts in a very 
similar way to your car's radiator. In a car, the heat exchange is between 
coolant and the air, in the boat between the coolant and the outboard water.

Is this for only Diesel engines  and in sea water?

If you take the end caps off the heat exchanger, you can see the tubes the raw 
water flows through. Flushing and replacing the coolant does not touch the 
inside of these tubes. To truly clean out the heat exchanger you need to remove 
these caps. I stuck mine in a tub of hot water and detergent, which worked OK 
for mild cleaning. I could seen into the tubes and there was nothing but a 
little slime. More robust measures are needed to remove scale and barnacles.
Back in the day it was common to get car radiators boiled out at a radiator 
shop. If any shops are around that still do this that will clean a heat 
exchanger too.
