So my final final answer after much hemming and hawing... I am going to stick with the 115.
While, I believe (apart from the marginal upfront cost) there is no material benefit to get the smaller engine, and I think the 140 would be better. I know the difference would be negligible, and many smarter folks than I are advocating the 115.
A few other things influenced my decision
1) Resale: it seems like the community prefers the 115, and that matters to me
2) when I asked the folks at the dealer, everyone said they liked the 115 hp more. When I asked why, the response was (paraphrasing) "I don't know, I just really like that engine". I put a lot of stock in that gut feeling by a pro and that was a bit of a clincher.
3) Safety: There is a non-zero chance friends and family will borrow boat, I don't want to have a safety discussion of how much throttle is too much.
There is a final point which is my wife told me to get the 115... so I guess the other points are actually erroneous.
