[PSUBS-MAILIST] temporary propulsion

[hank pronk via Personal_Submersibles]

Hi Brian, In the end I think you will be way ahead to pick up two 50 lb trolling motors and clamp them onto your sub for harbour operations.  You can also  buy 100 lb thrust motors here in Canada (Vancouver) for 600 dollars each.   You can leave them just as they are with no modifications, then sell them when your done testing.  You can oil fill them and use them on the sub permanently.  By the time you buy a gen set and motors, housings, and seals, you could have a couple of those 100 lb motors.  Doing this will also give you a sense of what you need to push that baby around, two of those motors (100 lb thrust)  will give you 4 hp.  Hank

 Hi All,                     Been thinking about how I'm going to get around the harbor with my sub.  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.     Since on my sub I will have dual motors on each side, port and starboard, I was thinking to also have additional motors facing foreword to stop my foreword progress ( a brake)   .     These dryer motors can be got really cheap , new they're about $75.00  I'm pretty sure they would be ok flooded with oil.   So I would have a total of 4 motors , two on each side one going frontwards and one opposing .  It would be a totally on or off drive of course , with no speed control.    Here's a video of the motors I'm talking about.       https://www.youtube.com/watch?v=uIrCUh1S8x8  Brian
