I have a 2006 Merc 115 carb 4 cyl. that I wanted to bump up to 125. All the info I found and people I talked to said all I have to do is change the jets in the carbs. Bought all new jets and now I have more power on my hole shot but once I start trimming out, all i can get is 4000 RPM and it sputters like it starving for fuel. Any suggestions.....
