I have been fighting a water pressure issue for weeks. New complete pump kit. New poppit valve. water system flushed and cleaned. No debris. Water pump is working just cant get over 2 psi out of motor on hose with pressure guage straight off motor. in water max 6 psi at 5000 rpm. noticed a lot of water coming out around shift shaft with hose connected. More with motor running. Have never seen this problem before. Any suggestions. Oh good thermostats.
