Re: trim sending unit and water pressure
get an infared thermometer!!!!!!!! fast.... if you are really only getting 8 psi....you could ruin your motor fast......check your head temps while idleing for 15 minutes...just to make sure the motor isnt overheating at idle...then run the motor at maybe 3000 rpm for 1 or 2 minutes then check the head temps....
if good run at 5000 rpm for 1 minute then check the temps...
thats if you dont have a temp guage( which i highly recomend)
