Merc Opti 225 - 05 vs 06
 

I am interested in repowering my 29 ft Sea Fox with a pair of 225 Optimax
Merc's. Taking off the old carbureted 225's. Have gotten prices on 05's
and 06's with the o5's being $2,900.00 less for a pair. Seems like alot.
Is there very much difference between the two? Any suggestions.
