My 00 yami makes this weird noise that I can only really hear when I lift up the seat and listen to the engine. It knocks about every .5 seconds and its a constant thing. When I get it on the water it runs perfect but I am hesitant about this and am going out in big winds tomorrow .
Not sure if its coming from the pump area but I was thinking mounts or exhaust. The engine shakes a little because of it
