>Let me know how that works.  Last time this was up for discussion, I thought someone had a pretty good idea with a pair of locking oars.  If they could be designed like a two-piece custom-made pool cue Leroy Brown, they'd fit nicely under the seats when not in use.

I don't think I would give up my 4s Tohatsu for an electric.  If need be, I'll just paint it green...
