    High pressure showing on water gauge

    At WOT my 30 lb. pressure gauge pegged out over the 30 lb. range. Changed out the gauge and line and it shows the same thing. Is this the "normal" pressure for a 150 4-stroke Merc. Never heard of an engine running this high. Could I have other problems like pluggage downstream from the nozzle? I bought the boat used (2016) so I have no history of performance. Serial number of motor is 2B245490
