Hey NELACAT. 250 SHO ON COUGAR update: I have been running it for almost 4 weeks and I have approximately 19 hours on it. I am way impressed overall with the performance. The holeshot is incredible. Midrange is very strong (I had a fishing buddy in the boat and I was running about 4 thousand and I opened it up and he was amazed at how much it pulled him back in the seat). In regards to top end numbers, it is running 79.3 with 2 people in the boat, 79.6 with one person. I have been told that the more it breaks in the more it will turn. It is only turning 5700 rpms so far. And by the way, when you launch the boat in the morning there is no stumbling and sputtering… very smooth. love it.
