So I've owned this boat/motor for 3 years, have had a minor issue going from idle to full throttle, it has a 3-4 second hesitation and then it jumps up and goes like it should. Idles fine and planes out beautiful, runs like a rocket. I decided this year to have it looked at before high school tourneys start back up in August. After telling mechanic what my issue was he asked about the carbs and last time they were rebuilt, I've owned it 3 years, unknown when they have been rebuilt if ever. He said more than likely the jets are stopped up. So I bout 4 kits and he rebuilt the 4 carbs.
I took it for a spin and it was the same or even worse during the hesitation period. Again idle and plane were great, super fast for a 125 motor. He took it all apart again and said he thinks the #4 carb needs to be replaced. So I ordered a carb, but before it came in he called me again and said that wasn't it he thinks the 4th cyl piston is scorched. He said he did a compression test on all 4, got 125 on 1,2 & 3, only 95 on 4 so he said the piston and rings were possibly bad and needed a new powerhead but he didn't do that kind of engine work. The guy he recommended that does it is 9-12 months out on work.
Changed plugs and fuel filter first of this year. Fresh gas in tank with ethanol treatment.
I've done a little reading and someone mentioned the fuel pump. So tonight I did the removal and manual fuel pump test and from what I can tell the diaphram is ok because it didn't leak on me when pressurized.
I have a buddy that just did a powerhead replacement last year and he's offered to assist me. But I'm wanting to make sure I am headed in the right direction before spending unnecessary money that isn't the solution.
Any thoughts, ideas or tips are appreciated.
