      With Autumn here & winter fast approaching its time to start thinking about a winter rebuild project.

      My Archer 650 – 6.5M Offshore has been sitting around gathering dust since I stripped it down to paint two years ago.

      As most will remember the original build had the boat equipped with twin outboard motors powered with big Axial Rock Crawler brushed motors. It went well and looked great but there was never ending maintenance required on the Outboards due to running in & cooling with salt water.


      The second rebuild saw it equipped with twin inboard motors (same as above) but still salt water cooled. This went well and required only a flush of the cooling system with fresh water after every use to keep it all working. Even though this arrangement was a bit heavy on batteries I intended to stay with it and to that end the boat was stripped down for painting & finishing.

      Before I got around to it the Aquacraft Rescue 17 came along and when upgrading that (with grateful input from UncleG), I opted for an air cooled brushless motor & ESC, which works a treat and uses a lot less power.


      To that end I have ordered two more of the Turnigy D3548/6 790kv motors & two HK 2s-4s-60A (w/reverse) air cooled ESC’s. May need to modify the motor mounting tray slightly but that shouldn’t be an issue with the 3D printer on hand to manufacture whatever is needed.

      More to follow.
