1990 Johnson 200 GT water pressure and voltage

[passingthought]

I am wondering what the normal water pressure for this engine should be it doesn't go over 10 psi even at full power. The telltale<br />drain always has a constant supply of water leaving and it doesn't seem to be getting hot Also the voltage being produced by the<br />engine seems to be high at idle it's around 13 volts and rises as you give it the gas it goes over 16 volts at full throttle Thanks in<br />advance for any insight.

WELL YOU SHOULD HAVE 7 TO 8 PSI AT IDLE AND AROUND 20 TO 25 AT WOT AS FOR THE CHARGING PROBLEM. ARE YOU GOING BY GAUGE ON DASH OR A VOLT METER? THE VOLTAGE REGULATOR SHOULD IF WORKING PROPERLY SHOULD REGULATE THE VOLTAGE AT AROUND 14.5 VOLTS. DASH GAUGES ARE NOT ALL THAT ACCURATE USE A METER AT HOT TERMINAL OF STARTER SOLINOID TO TAKE YOUR READINGS GOOD LUCK
