ok, neighbors boat engine is an 86 model 175 supposedly. i say this because it was a state owned boat and looks to be cobbled together. its got a 175hp powerhead on it and what looks to be 3 mismatched carbs that have had varying degrees of "work"/rigging done to them in the past. here's the numbers on the top side of the mounting flange for each.
#1 = 66605 S 621400-061 p5Y01B
#2 = 66403 S 621400-131 p5702P
#3 = 664038(4?) S 621400-141 p6801F
can anyone tell me more about these carbs/factory jetting etc?
I tried plugging numbers into google and got nothing.
