Thanks Tommy, pretty impressive. I do like to fool around with things, but that is pretty high tech. Here is a couple of pictures when I was still playing around with powering my kayak. The top picture is my first try with my yard blower. Made the mistake of launching at a public boat launch. The boat seemed to attract a few folks. Got to listen to them chuckling for about 5 minutes cause the system was inefficient and slow. The water pump one below worked much better. Having learned a lesson from the public launch, this test was in 'private'. I then graduated to a modified 'weed wacker'. That worked the best of all.
