We require underwater generators and hence, would like to have the
names, addresses and telephone numbers of the major manufacturers.

Please respond asap.

Is the generator expected to be submerged totally?  How does it get
its air to run?  Are you expecting it to have its own air supply?  You
might do better with batteries or a cable coming from the surface.  A
gasoline generator would use up a lot of air in a short time.  Also
how much power do you need generated (1,000 Watts, 10,000 watts,
100,000 watts)?

The genset will be on the jetty itself and what we need are the
electrodes, etc. for underwater welding.

Please advise.
