...or compensate the existing motors. The pods are strong enough to
stand the pressure, but the seals are more of a challenge.

Jon,
Harold Maynard said he's had a thruster flood a time or two
also. Might be a good time for a Minn Kota upgrade.

Vance,
you're never going to qualify for the "PSUBS Cold Weather Overhaul" patch
under those Florida conditions.
A nippy 35F tonight. I was
forgetting tools on purpose just so I could go inside to warm up.
:) In another month it will be warmer in my refrigerator than outside
and I'll be fondly recalling how nice it was when I pulled those motors
out.
In any event, I picked up an impact driver and it worked like
magic. Three blows and the screw was turning easily. The
starboard side motor backing plate was much tighter than the port side and I
had to wrestle it a little bit to extract it from the housing.
Disconnected the wires and brought it inside. This one has a Honeywell
tag on it instead of Advance Motor Operation. Given the difference
inside this motor housing compared to the port side, I'd have to guess the
port side flooded and when they went for the replacement motor Honeywell had
already transferred their motor division to Advance Motor
Operation.
Since I was having good luck I decided to tackle the big
motor in the back of the sub but was unsuccessful. I removed the prop
and mechanical seal, but I won't be able to use my crowbar technique because
the vanes on the kort nozzle are much thinner than the forward motors and
won't take the pressure that needs to be applied without bending the
vanes. I'm going to have to either find a good chain wrench to wrap
around the tank head, or get some 1/4 inch scrap metal and weld some tabs
onto the tank head temporarily so I can use it for leverage. I suspect
a bearing is gone on the rear motor since when I turn the propeller shaft I
can hear some awkward gritty sound. There was a lot of dirt between
the mechanical seals so that housing may have flooded at some point
too. If so, its probably pretty rusty in there and the tank head is
going to be difficult to get off. I may be done for the season
depending upon the weather but I'm glad I at least got the two forward
motors off.

rain, and I'm doing yard
work.
