Oops. Trim tab issues. Lenco edge mount 12X12 tabs won't work without cutting holes in the bracket (though Capt Chuck did this on his 23' with good results). A 9" wide tab would allow the cylinder to fit outside of the bracket, but it still is quite high.
Solution: QL tabs. I'd never heard of these. Volvo Penta has a history of pushing the design envelope and these certainly are different. They basically have a blade that drops straight down and creates a hydraulic wedge. Installation is a challenge as they must mount to a perfectly flat surface so the housing isn't distorted, which jams the blade. (Yes, been there, done that.) One nice thing, the thin profile makes them impossible to smash at the dock. They are a perfect fit and work really well.
