[PSUBS-MAILIST] temporary propulsion

[Alan via Personal_Submersibles]

What a beast! Do you need all that horsepower, as you will need a 
huge battery bank to take advantage of it. That is not a bad price with
controller included from what I have seen of other systems.You will need a pressure compensating system to take it down deep. How many motors? & how are you
going to configure them.

P.S. Really enjoying your elections down here in N.Z. can't wait for the next
episode of "Saturday night live"

Those little Honda generators are quite amazing , very compact, quite, and they sip the gasoline.  I noticed a lot of sailboat people would use them for house power instead of firing up they're onboard engines, they would set them out on the bow.

I'm thinking that for the time being I'm just going to run ( on the surface) a 2000 watt Honda generator and then for the motors , use these 1/3 HP dryer motors in a oil flooded housing, probably made out of aluminum tubing.  They obviously run with 120 V  AC power.
