    ……………………………………….…….…10 The Gavin needs little or no maintenance (either version). When all is well with your Gavin Scooter, the motor should NEVER get hot, it should never leak through the seal, and it should never need any kind of servicing whatsoever. These are continuous duty electric motors and are highly efficient.

  • Page 3: Access Port Plug

    The other thing to remember is that all batteries offgas - even Ni-Cads Never leave your scooter sealed or pull the trigger out of the water. If you leave it sealed, it may blow up and that can be extremely dangerous and cause serious injury.

  • Page 4: Battery Connections

    3/8 " ## 6-32 machine screw and some silicone to hold you over until a new body can be made (40 bucks for the body). Bill Gavin used to run them through like that, but it is not necessary for strength, and leaves open that quick fix option if you do mangle one.

  • Page 5: Motor Connections

    (remember they are threaded, and tightening the gold nuts will turn the gold fitting the other way unless held.) Make sure these fittings are tight so there is no intermittence in the scooter. If there is, this is the problem.

  • Page 6: Reed Switch

    If you do replace it, use the same fittings and be sure to sand off the little flange so it will fit in its hole.

  • Page 7: Salt Water Diving

    An easy way to rinse a scooter is to put it in a fill bin and run it a few seconds (with the pitch turned down). You can also use a hose and force water in under the clutch.

  • Page 8: Seal And Clutch Assembly

    Run the motor for a couple of minutes to break in the seal. You do not need to take the motor out of the scooter to replace the seal. Gavin Scooter User’s Manual and FAQ ( George Irvine 2002)

  • Page 9: Switch Connectors

    The length of the tow cord must be such that the scooter is as far out in front of the diver as possible and the diver's right hand is merely relaxed on the right handle, and so that the left hand can easily reach the shroud.

  • Page 10: Trigger Cable

    Usually , the way you break the cable is by catching the magnet on something while transporting the scooter. I try to keep that magnet at about the edge of the tail so it does not stick out. I also watch that when carrying and do not use that leg as a handle.

  • Page 11: How Do I Properly Balance The Scooter

    If you want a bias, make it so that your tow strap is on the area of the scooter that ends up on the bottom relative to gravity. This will allow the scooter to tow properly.

  • Page 12: How Do I Vacuum Test / Pressure Test The Motor

    Any connections need to be held on both sides to tighten or they will back out of their threaded slots. What Does The Vacuum Hand Pump Look Like? Gavin Scooter User’s Manual and FAQ ( George Irvine 2002)

  • Page 13: What Type Of Batteries Should I Get

    Then the whole motor cone has to be replaced, which is extremely time consuming. An easy way to rinse a scooter is to put it in a fill bin and run it a few seconds (with the pitch turned down). You can also use a hose and force water in under the clutch.

  • Page 14: What Should I Do If My Scooter Sticks On While I Am Diving

    What should I do if my scooter sticks on while I am diving? If the scooter sticks on for real, as in if the reed switch breaks or the relay welds shut or mechanically sticks, you can stop the blades with your hand and turn the pitch back while you are changing stages or decompressing, and then stop it again and reset the pitch when you want to travel.

  • Page 16 How To The goal is to test how long your batteries will burn without doing it on the scooter. Short burn times indicate bad batteries. (Trust me...) The circuit above represents the load of the scooter. 1. Wire the circuit. The resistance at E should be Ohms.
