Overhaul Scooter
The GavinScooters website has some very good technical information on scooters that also applies to Mako scooters (salt water prep, tow cord setup, seal replacement, etc.). Also the GasDiving.Co.Uk has detailed instructions and diagrams on disassembly of the propeller, seal and clutch.
This is how the back of the scooter looked before I started... I hope I get it back together.

The picture on the left shows the rubber cup seal, and the mechanical seal
held on the shaft with a snap ring. After taking the picture, I touched the snap ring, and it broken
into 3 pieces. Maybe on the next dive it would have let go, and allowed the
mechanical seal to fail. I feel very lucky to catch it in time.
