What Type of Batteries Should I Get?
Powersonic 33's for the long body and Yuasa 18's for the short body.
Where I Can Go To Purchase Batteries?
One place you can get them from is:
TNR Technical in Sanford, FL
(407) 321-7608
Ask for Wayne.
(If you get the other 33's that he has,
just leave out the small spacer since those batteries are longer.)
How do I manage getting off the boat with my Gavin Scooter?
For boat diving, what we usually do is put the scooter at the stern and have a
mate hold it steady so it doesn't fall in, then get suited up and go to the stern, clip
it to us, pick it up and jump in. If there is not a lot of current you can just have
them hand it down to you. If you are diving a single tank it is really easy, if you
have stage bottles and doubles it is best if there is someone to help a little.
How do I properly rinse my scooter after diving in salt water?
A rinse in fresh water after diving followed by a spray of CRC or WD40 around
the area of the seal will do a lot to prevent any problems. You do not have to take
the props and clutch off, merely use the little tube that comes with these cans to
spray under the clutch and into that area. The idea is to prevent the cone around
the seal from reacting with the salt and eating away. Eventually this process will
leave the seal unable to hold at its edges, even if the two seal plates are not
damaged. 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.
For more information about the damage that can be caused to your scooter fom
not rinsing it properly after diving in salt water, refer to the Owners Manual
section on Salt Water Diving.
