First, sorry for such a long post, but the better the question, the better the answer.<br /><br />TOPIC 1) 225 carb vs EFI<br />I have been searching the past 3 months for a replacement powerplant. I have narrowed my decision down to a 225 Merc FFI or carb model.<br />The EFI motor in ? is a 1997, rebuilt, I am curious as to the opinions. Are the EFI motors as reliable as a carb model. I know I have limped home on many occasions with many outboards and always was a carb model. I am curious because in an automobile engine, The ignition module is either 100% or 0. I imagine this holds true with Outboard also? <br />I am also curious as to the difference in cubic inches between motors, i.e. 153 vs 185. Is this accomplished through bore, stroke or both ?<br /><br />Also difference is gear ration. 1.75:1 vs 1.87:1, can I tell via lower unit which gear is contained within? I am also curious as to WOT RPM, 300 more for EFI, Is the difference in timing or fuel management?<br /><br />Is there any way upon inspection of this motor to test EFI related components with normal test equip V/O/amp meter? What should compression be on 225 EFI.<br />And can someone please supply serial number range for 97 EFI 225.<br /><br />I will end with that, still many ?, but will scour the net for more answers.<br /><br />THANKS TO ALL WHOM REPLY!!!!!!!!!!<br /><br /><br />Yo ho ho and a bottle of Rum~
