We've been very happy with the Honda 130 and 9.9 kicker Les installed on Jammin. It seems to me that Jammin runs best at about 5kts with the kicker or 130. The kicker is primarily a get home engine as it is noisier than the 130. It seems to be powerful enough.
I would not have this boat without an autopilot. Slow and quiet with the autopilot is often the way we like spending a day cruising.
