18-lb thrust Watersnake can't weigh more than about 4- to 5-lbs. It pushes my Revo-13 along at about 3 mph on low and about 4.5 + on high speed. Wind does make a difference, however.
FYI, Tom's motor mount is great but I have noticed that on the one I made, the conduit clamps became a bit loose, probably due to slightly large screw holes, allowing the motor to wiggle quite a bit... I made a small dam with tape around the PVC fitting and filled with JB Weld to cover the screw heads... now, they,re as tight as... well, you know...
Hope this helps someone...
Wow! That's a lot of speed you're getting. I put the same motor on my 16' adventure (Kirkman inspired mount, thanks again Tom!) however, I'm maxing out at 3.2 mph. I wired in an eBay pulse width modulator for better battery economy. It's interesting, my top speed is reached at about 3/4 full on the dial. Full power results in slightly slower speed. I wonder if this is the point where I run out of needed prop pitch or power to drive what's there? I'd love to get more speed.
