    No core floor

    I don't have room to slide 1/2" plywood under the open bow walk through. I built my stringers a little too tall...also I took rotten wood out with my bare hands...I will not put wood back into it. I was going to use Coosa, but I don't have room. I am aware of the weight issues, but thickness...

    1990 Jet-N-Cat powered by a 650 Yamaha

    My Little jet boat is cutting out...spitting and sputtering, and won't get up to speed. It sound almost like it is blowing up when it cuts out, but there was no aluminum on plugs and the compression is 125 or so in both cylinders...is that ok? I hope it is just a fuel problem or something...
