Need some Mercury v6 Identification help

[gotboostedvr6]

I just picked up a boat with a blown V6 merc. I think its a carbed 2.5 but how can i make sure? Im tearing it down now.

Serial number is damaged but looks like

N998029
Could also be
N993029

date code cast on block looks like 1995

carbs are 3308-9672-c

5 reed valves per side

any ideas?

measure tha holes.. will be 3 1/8" (2.0) or 3 1/2" (2.5)... number will be 0D, 0G. 0T for a 2.5 style "fat block"......

hate ta let ya know that's a 35 horse motor number... What ya got is a "fat block" 150 2 liter ('91 or newer)

The 8 might be a 3 lol

[tlwjkw]

makes no difference.. A, B, C's xxxxxx were 80's and 90 (last year of tha old style blocks).. ALL 2.5 style blocks will be OD, 0G or 0Txxxxxx.. it may be a '92 or newer 'cause its got tha two rectifier/regulators..... whats tha other numbers stamped with tha 95?
