Buddy has 2002 330 with F225s. Cruising speed and top end have both decreased about 3mph (from ~25 to 22) over the last season and a half or so. Props were re-worked at the beginning of last season and he was told by the prop shop that they were fine at the beginiing of this year. The prop shop is highly regarded. However, other than an additional coat of bottom paint there really is no other change from year to year to affect the performance so we're thinking the problem has to be related to the props. He is considering a new set of SWS 15 1/4 X 17s, same as the originals, hoping that he will regain the 3mph.
