As stated above, the throttle plates are NOT "exactly the same". Very close/similar, but different enough to require a separate part number.

They sure look the same to me. Same throat diameter and same part# on the butterfly valve.

Perhaps one of those isn't what you thought it was (ie: Original already been changed, one you got not what you expected, etc).
Definitely different part numbers, see below image:

No need to argue about it, though.

That might be the case, it came off of the same engine that the 115 ECU did. I have noticed there is several different part numbers for the 1.5 Optimax 115 throttle body depending on the year and some years even show a few different part numbers. Same goes for the ECU, I found at least 10 different part numbers for a 115 ECU, not sure what the actual difference is. I kind of believe that Mercury just changed part numbers a lot to confuse people so they wouldn't think parts could interchange with other years or motors when they actually can. The ECU I got came off of an 07 and it works fine on my 2010 even though they show a different part number for a 2010 ECU.
Well they do change part numbers a lot, but not for that reason. Most of those part numbers supersede to newer numbers either due to some improvement, a vendor change, etc.

Hope you never need to make an insurance claim.
Could give the insurance company a reason to deny the claim if the motor has been altered like that.
See what happens when you have to make a claim that has injuries or property damage. And it's tough to "change the parts back" when the boat is impounded.
This is perhaps one of the biggest risks. Whether or not you "caused" the accident or injuries would be up for debate if a decent lawyer recognized the modifications that had been made. Makes for a pretty easy argument path to "wanton disregard for laws, regulations and safety". Have seen this happen once with an overpowered boat.

I guess common sense ain't so common anymore....LOL
Is it worth another 5-6 mph?
Yes it was well worth it. It was actually cheaper than having the ECU reprogrammed to a 115 would have been, and I have a spare that I can use when I have to do an oil pump prime so I don't have to put the one I am using now in break in mode, seems like a common sense idea to me.
Is your boat rated for a 115? You do realize that boats under 20ft are subject to Coast Guard regs such as the horsepower rating of that is on the boat.
Update, I put 50 hours on it this year and it has performed flawlessly.
Yes it is. I see 115 HP PCU's on ebay for $400 or so. Will most likely go that route.
