I wouldn't be too quick to change over to more power. Sure more power is sweet but, There is something to be said about a nice running carb engine. It fired up for you after all those years and it is easy to work on and maintain.

How about sharing pix of the rest of the boat?

S&F doesn't have enough bandwidth to cover what will and will not work with tha V6.. best ta jus post a question or two at a time and you will get an answer pretty quick on here.. sounds like ya gotta case of tha sickness... welcome.

they are both '78 200 2.4's..

if ya add a "0" as tha first number in that type serial number it will pull up on most sites.... they incorporated that to all numbers when tha first "0D" series came out seems like.......... i don't remember any 0A, 0B, or 0C's till that happened.. they were jus A, B, or C then tha number............ was a long time ago.

From process of elimination, they are 1978 2.4 200's. The Mercury V6 came out in 1976 starting with serial number 4301235 as a 3 1/8" bore 2.0L 175HP. It remained a 2.0L until serial number 6618750. So, it cannot be a 175. In 1978 the 2.4 3 3/8 bore 200HP came out starting with serial number 4839034. The 225HP 2.4 came out in 1980, but it started with serial number 5615282. your serial number is too low to be a 225Hp.
