After having my boat at the mechanic for five weeks with no service I picked it up. My problem was that the boat is sluggish, it will only push about 5k rpms and it seems that I have to push the throttle down a lot further to get it spun up at all. I got it home and changed the plugs, fuel filter and the fuel water separator. I had about half a tank of fresh fuel left so I burnt that out, filled back up added some startron and took her out. I am still getting the same performance out of the motor.
A friend told me it could take a tank or two before it starts running right. Is that normal? Another guy told me that it could be the coils or stator, but I figured I would start with the more inexpensive stuff that I could do myself before I moved on. Any suggestions? The motor is a 2006 merc 4 stroke.
