[QUOTE="Webygail13, post: 390656, member: 18519"] Finished my build today. 87 Alumacraft 1756. 2003 Merc 90/65. I used the CMC static riser. I tried to set it up with the leading edge a 1/4" higher than the bottom. I put it in today and when i opened up the throttle, it just revved and sucked air. Would get on lane. The motor also shook really bad. I eased up and throttled up slowly and it did better. I got it on plane and it ran about 30mph. It was lnt peeing a good stream though and was making a sound like it was sucking air. When i stopped and got back to idle, it almost sounded like it had an exhaust leak in it. So, two questions, is my motor too high and could i have possibly hurt my motor when i ran it. I only went about 500 yards down and 500 back. Thanks for the help. [/QUOTE]
