 Tim, for sure if you use the original location for the shaft it is way out of balance.  I have the motors sitting on saddles, not the shaft.  Hank

Thanks, Hank.

I am just considering balancing the thruster around the shaft.  With the shaft horizontal and sticking out of the hull the tail of the thruster is much heavier than the nose, and it wants to pull itself vertical so the thruster points up.  I need the thruster to be reasonably balanced on the horizontal shaft n the water so that it is easily pivoted from pointing strait down, level, to pointing straight up.

Tim. The trusters can slide in the mount so they are mounted close to centre of gravity, not that it matters because the mounts are very strong.  One nice thing about this sub is that it needs a lot of weight at the back, so I can use all the steel I want.  Now the front is another story.  I have to keep the front on a Jenny Craig diet program.

Hank,

In notice that you have the thruster horizontal.  I find them to be very
tail heavy... are you counterbalancing them in this position or just taking
up vertical rotation tendency with a tight joint?

Tim

Jon. Here is a picture that shows my solenoid valve inside an oil filled
enclosure behind the sail. The enclosure is a rubber plumbing boot Hank
