Mercury 2006 200 hp Optimax

For 343 hrs since new the WOT has always been 5200 rpm. It dropped down to a max of 4800 rpm. Took it in and had new plugs and new reeds installed as they needed it. Test drove it and still 4800 rpm max. It starts good , idles good and runs and sounds good but wont rap up to 5200 rpm. Any ideas ???

Check the voltage on the TPS. WOT should read close to 4.5 volts. Start there.
