I have a 2016 RT 188 and love it. Mine has a Merc 115 four stroke and 80 lb Fortrex, both are great. The boat is stable, well-built and economical. My only complaint is that it is a little hard to center the boat when putting back on the trailer.
Looks like we may be neighbors if your in Keller. Not to be a know-it-all but if you are having issues getting the boat on the trailer centered, you may be backing the trailer in too deep to start. Most folks do.
Try this: Have your partner back in about 80% of what you think you need to get it on the trailer. There is a sweet spot. This may take a little experimentation so go to a ramp that is empty so you can practice.
Once you are straight, have your partner back up about a foot, (make sure the motor is at the top of the TRIM cycle so your prop doesn't hit the ramp) and then power it up until the bow hook hits the bumper.
