[QUOTE="LarryMc, post: 427712, member: 13895"] I've had them on a jet boat without a tunnel and I was not happy with them. They are very thick (about 1/2" as best as I can recall) compared to the steel fins and are installed with soft stainless all thread rods and if you hit anything with them, the fin will fold upwards and bend the rod. This will enlarge the mounting holes and once that happens, it's almost impossible to keep them on straight. They are cut back to fit up against the both the bottom and side of the intake and they will slip up and fold out once the holes are deformed. They might work better on a tunnel boat where you won't be as likely to hit bottom. [/QUOTE]
