Hello Emile,
I’ve been using WD-40 in the
thrusters too. WD-40 is basically made up of a combination of baby oil, Vaseline,
and a variety of “alkanes” (like nonane, decane, undecane and
tridecane). The great thing about alkanes is that they cannot be ionized and
therefore cannot bind with hydrogen, making them water repellant. One thing I
like about WD is that it doesn’t produce as big of an “oil slick”
on the water if some ever escapes. Oils slicks following your sub are not
good!!! I think that the gas produced is cause by arcing of the brushes in
compounds with slightly higher vapor pressure. The only real downside to WD-40 is
that the Vaseline component can degrade the rubber seals over time (like any
petroleum based lube) but it takes awhile.
Cheers!

Might be time to build
a tank for testing. I like hydraulic oil better than silicone. It is actually
slicker. We used it by the drum with the Pisces boats.

Subject: [PSUBS-MAILIST] compensating
Hi, The compensation
subject again…
We compensate the
Eurosub engines with WD40. Work fine at depth but somehow the engines
create gas so we have to pressure relief the compensation bottles every few
dive hours. I try to get thin silicone oil to see if that works better.
For the time being I
wonder how deep
Any thoughts/ expirience
??
