I'm toying with the idea of putting an electric motor in a boat I have for pootling along the canal. It's a small boat and does 4-5 knots with a 3hp seagull so I reckon 1000 to 2500w should be adequate. The seagull is terribly noisy so spoils the idea of having a quiet day out. Starter motors are an obvious thing to look at but are not really intended for continuous running. Otherwise I can get something for about £150 but I'd rather have something second hand and salvaged - i.e cheap (so I can afford traction batteries!) Any suggestions of where to find something? Hydraulic pump motors for tippers seemed a possibility. What else gets scrapped that has a motor in it? Incidentally I know that: 1 I'll need a motor controller 2. The boat will have to be safe. 3. The batteries will be expensive etc. etc. etc.
