In response to the off-topic: Lawyer up if you feel it was wrong...my $.02. Don't let something like that go unnoticed by them.
On-topic: I'll ask him if he'd actually sell the motor and what the hours are.
Semi-on-topic: I have a full tower on my boat (23' center console) and while I enjoy getting up there, I enjoying sight casting from up there and I enjoy having Lee Jr's on a center console, it cuts down on fishing space by forcing you to pass the rod outside of the tower leg to get up to the bow if you started in the stern. It also is making me rethink my trolling setup now that I've double-rigged my outriggers and have a center rigger because one of my trolling rod holders on each side (that I previously didn't need to use) is located forward of the aft tower legs...so hooking the line up to a release clip would require some deep thoughts and graceful movements.
Also, your boat appears to be a little shallower V, but at 24deg, my boat has the keen ability to separate the boys from the men in terms of sea sickness, with a tower, an 8'-0" beam and the 24deg at the stern you can anchor up and wait for the green faces even on the calmest of days. Sure gets out there smooth though
Just in case you were waffling on what type of top to go to next...
