Running a fury 4 blade prop, The engine when its idling gets other peoples attention at boat ramp, when running you can talk to your partner and hear each other, hole shot with full tanks and live well is impressive, mid range running when you give it some throttle puts you back into the seat, opted for the digital shifting package well worth the extra money for the performance you get, if you go this route have patience waited 6 months to recieve motor before rigging process,fuel usage is better than the optimax, the engine has been broken in as per mercury specs, next week i will give it a 6200 rpm gps speed reading and post, Thank you bass cat for making a boat that is so well built a guy like me can make it like a new boat with all the new bells and whistles.
