That wasn't what I was getting at, the Mercs are OK, but depending on what you want to do with it it may not be the best motor for every application. If you want it to match, and that's your priority it's fine, but we don't know that until you say what preferences you have and how you plan to use it.
They are jetted very lean at idle, which makes the RPM's hard to control if you're trolling slow, plus they tend to vibrate at trolling speeds. Higher RPMs aren't an issue. Reliability hasn't been a problem, but like just about every other small 4 stroke they are very sensitive to crud in the carb, so you should learn how to clean it. Drilling out the cover over the low speed adjustment screw and richening the setting slightly will make it run much better. The lean jetting makes it very cold blooded, especially in the winter.
Some people like the shift in the handle feature and some don't, I like it.
Yamahas tend to run smoother and quieter, and are far more popular, but have an issue with the tilt and trim pump holding up if you use it a great deal.
Hondas have a charging system that puts out far more amps than the others if you need to run electronics while trolling.
