[PSUBS-MAILIST] temporary propulsion

[Alan via Personal_Submersibles]

Hi Brian,
what happened to the high powered motors you were looking at a while back?
These motors are huge & only put out 1/3 rd horsepower. Minn kotta is 2hp. There is a 
lot of work making a housing for them. The shaft would have to be extended to fit another bearing, seal & the propeller, let alone all the work for a housing that is bolted together &
sealed with a wiring entry welded on.
If you are just wanting to do buoyancy / stability tests before you invest in thrusters,
why not have a small inflatable tender with outboard to drag it round.
Alternatively look on Cliffs project page on his Minn kotta modification, as he has done
some good work on them that may be helpful.
Cheers Alan

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.
