2004 mercury 50hp outboard carb float adjustment and carb screw settings

[TonyTracker]

Hello I’m struggling to find the proper carb float adjustment measurements and carb screw settings after rebuilding my 3 carburetors. Carb screw I’m sure I set back to where they were previously set so I’m less concerned with that as compared to floats. The three floats all seem to be set slightly different from each other. Once I get the float situated, I will get the carbs back on and hope the cleaning and new gaskets fixes the loss of power! Any help is greatly appreciated!

Did you find any gum , dirt or contamination in them ?-----Did you do any other testing on the motor ?

Not much gum compared to ones I saw rebuilt on YouTube. I had a marine mechanic service it last yr due to a wiring harness melting and once I got the boat back it wouldn’t go above 8mph full throttle when it had done 33mph previously. His reply was “I knew I should have rebuilt the carbs” once I told him of the loss of power. $1500 later I’m trying to figure it out on my own. I guess I will have to just purchase the service manual to get the carb float settings before I put the fuel bowls back on the carbs.
