What with Christmas I've got a little less done over the past few weeks, but I have made progress on the pump. A while ago, Shapeways had a free delivery sale, so I bought one of these: www.shapeways.com/model/234810/gen-x-pump-kit.html, not necessarily thinking I'd use it in the Golo, as I was hoping to find a pump small enough to fit between the propeller shafts (i.e. < 30mm diameter). When I got the pump I realised that it would just about fit in the bow of Golo, so I decided to use it. I don't have an ideal brushless motor around -- that is, something with the shaft extending from the stator mounting plate, so I built a support to hold the motor in place. You may call it Heath Robinson (or Rube Goldberg on the other side of the Atlantic), but I prefer to think of it as a bit steampunk. The mount consists of a brass plate and a lot of M3 Nylocks. The origianl motor mounting holes on the pump have been filled with epoxy. I've drilled some holes in the bottom of the hull for the three vertical bolts. It pumps a lot of water -- I can imagine replacing it with something smaller in a future refit.
