I hate to hijack your thread but your numbers raise a question with my set up. I have a 2100 with a 04 225 EFI. I run a 27 trophy. While I have seen as much as 82.4, most of the time I will it the limiter (5800) right at 81. Just did it this weekend with a half tank of gas, me 200 (lbs), a tournament load and 2 full live wells of fish. While I do try to limt my gear weight, i still think i am running pretty heavy. Is the XS not supposed to be a faster motor? I would think having the higher RPM limit you would be faster then 78 and would be able to run more prop? Do I have a hot motor? I am just trying to understand.
