Almost every manufacturer will have a cross reference to your filter (Fram, STP, NAPA, etc., etc.). Check on-line, at a marine equipment dealer or auto parts supply house.
AC Delco pf-25,if you have extra room under the filter use a AC pf 35 ,it is the same filter but larger.You can get the filter at Kmart very cheap.I may have the letters wrong,check for pf or it may be ph .the numbers are correct.By the way a fram filter is real crap!! CC
