First time post, this looks like a great and informative site. I picked up a 998si for boat, which is primarily used for fishing offshore. Problem is the hull is a flat back stepped hull. I attached the transducer to the step but it only took a few minutes for the transducer to get flipped up as it was a little bumpy heading out this weekend. I couldnt figure out why the depth reading was 30 feet off all day until the boat was on the trailer. Flipping the transducer down is impossible without going for a swim 30 miles offshore. Is there any solutions, maybe perminatly mount the transducer down? Thanks in advantace! Brent
