Was loading on the trailer to get ready to head out tomorrow and noticed the 50 is not up to speed. Engine is running fine, good power, and running up to full RPM. Just it is maybe going 1/3 the speed as normal. I flipped it up on its back and pulled what I think is the CVT drain (12mm plug next to the gear case drain), and no water came out. He does take it in water a lot, and sank it pretty good last time out but was running fine when we put it away. Any idea what is happening?
