Looks like this guy did. Not sure what year your boat is or if it has the enclosed transom or not but the max horsepower for a 1992 GW 25' Sailfish is 400hp. Not sure how a motor with 100hp less than the max would handle but I'm sure it's been done more than once before.
Inactive: Grady-White 25 Sailfish Boat in Pensacola, FL | 122241
Pre-Owned 1987 Grady-White 25 Sailfish walkaround fishing boat (300 hrs) for sale in Pensacola, Florida (near Mobile, AL) - $22,500. View photos, 1 video, features and a very detailed description.
Not repowered but rather 'powered'. Grady offered a single diesel i/o version of the Sailfish. Great boat but maintenance was costly.
I did. 300 Evinrude G2 on 25 Sailfish open transom. Cruise at 4600 rpm . 1.8 mpg . 13/14 gph at 24 /25 knots.
