Excuse my ignorance but im not sure, its on a 2000 Evinrude 225 right now and was on a 99 Merc. 200 EFI. Just to much pitch for my 200 but runs real good on my neighbors 225.
You might call Performance propeller at 423-842-7767 and see if they can loosed it up for you. I just switched from a 27 trophy to a 26 on my boat as well.
