[PSUBS-MAILIST] G.L. summary Pressure Hull

[hank pronk]

Hi Vance,
I did not have it in the sub so it was not hooked up to the amp gauge.  What do you mean by linear.

How much did your amperage increase at depth? Was the load increase linear?

I just did a 1/2hr run on my new drive with the shaft tube full of water and under 500psi.  The seal works perfectly and there is very little heat build up.  I was surprised how much the motor pulls down after 200psi.  I assume it is from the shaft pushing into the thrust bearing.  Also I am running the motor on 12v because it spins to fast on 24 with no load.
