That motor is a straight 4 cylinder with a feature that disables two of the cylinders below 2400 rpm. This is to improve idle and trolling fuel economy. The only down side is that the motors run rough in that transition zone between operational modes. On most boats, this occurs while climbing out of the hole onto plane. Running steady at that transition speed would be plowing bow hi, not quite on plane. That is not how you want to run your boat, so that rpm range is quickly passed over and all 4 cylinders kick in. On a very small and light boat that might fully plane in that transition rpm range, this motor would not be a good choice. Take if for a ride and see what you think for your self.

All the 100, 115 and 125 in line fours are the same with respect to minor differences with carbs. I have owned two 115's. The first on I put on a Montauk and, I did not know it was a 2-4 prior to the purchase. The second one I purchased on the back of my current 17 outrage. I bought the boat because of the hull. I have the boat in for repower with a 150 carb. I do not recommend any 2-4 motors. They do not run smooth or consistant. You will be disappointed.
