External Drive Motors for 1/24 scale RC Sailing Ships

Have been asked about the external "drive pods"
Some detail in this old post, and some pictures too.

The latest, final design was simple - PVC pipe endcaps were epoxied over the two ends of the motor. One cap sealed the open end of the motor. The other cap was drilled for a model submarine shaft seal. The wires were passed through a hole in the endcap and also sealed with epoxy.
No water gets to the motor.
The motors I used were from a surplus store. They are made by Faulhaber. Dimensions approx. 25mmD x 50mmL. They are sealed motors and run with very low current (they are high efficiency).

Here is the Faulhaber motor product page:

The drive shaft seals are from a RC submarine parts supplier:
Mikes' Subworks.
