The initial thrusters that were described earlier on this were no good. They easily cracked and then leaked. With (a lot of) help from my friends Roland and Luc (sea earlier posts) we designed some brand new thrusters reusing the original motors. They were made in aluminum and look very professional, sealed with O-ring and something new called a xxxxxx ring. (Will fill that in later when I remember).

These are pictures of the completed thruster :
