Hi Boatmad
Need some advice.
I have a merc 200hp 2.5L offshore motor which appears to be fitted with an XR2 2.0L power head, the carbs and electrics are stock 200hp 2.5.
4 up with a boat load of gear and half a tank of fuel the boat will pull 54mph (GPA and speedo agree) at 7500RPM with a laser 21 seemingly with out any distress
Boat has allways had a very rough idel and poor holeshot which I have been trying to improve.
Pulled flywheel off and found 5 out of 6 outer magnets broken and loose.
Questions
1. Is this likely to be cause of rough idel and missing?
2. should i replace it with an XR2 flyweel and 18A stator?
