i have a 2001 225 ox66 saltwater series yamaha and its runs great but lets say the time comes to repower is it possiable to us a 250 powerhead ? would it be cost affective? Besides I guess larger injectors would i also need a new ECM ? Is the lower unit compatable? I was thinking it would be heck of alot cheaper than a new motor; and would it be noticeable improvement in performance .
