Hey so i just bought a used boat I don't have any history on the motor. The motor runs but seems to have a cylinder not firing. I did a compression test left two cylinder are 95 and right are 105. also did the 7/16 spark test and it passed. cylinder 2 seems to be not firing. its strange because on the hose I cant hear it but in the water I can. another thing is on the hose the engine runs and throttles up fine but in the water it will not accelerate. I'm going to check fuel pressure tomorrow but I'm thinking I need to rebuild the carbs. the plug in cylinder 2 looked brand new. Just wanted to know am I heading in the right direction or should I be checking something else?
Also i seen some cheap carb kits online is it safe to use aftermarket or should i use Evinrude. and what's the deal with carb cleaner some say soak them but in what?
