The carb'd 60 degree V-6 Johnrudes (150/175) are fairly light, and also worth considering. However I'd avoid the late 90's models, built when OMC was beginning to struggle before the bankruptcy. An engineer I worked with before I retired became the chief engineer at the OMC/BRP test center near Stuart, and told me that BRP really cleaned house and made dramatic improvements in quality when they took over, so he was very enthusiastic about the later motors.

However the main thing with any used motor is it's condition, compression, maintenance history, etc. Those factors and availabilty of nearby dealer support is probably more important than a particular brand; most motors are pretty reliable IF properly maintained.
