Ranger 118C 150 Pro XS Ser#2B113483 23p tempest plus issues with temp and water pressure. At a high idle (5-6mph) engine wants to get up in the 190’s and have to let off to cool down to 150ish. WOT 5350rpm temp is between 98-111 degree with water pressure between 8-10psi. Been doing some Reading and everything is pointing towards thermostats or poppet valve. As for water pressure idk what to do cause at idle the pee stream is fine but at WOT it’s more intermittent spraying or not a stream
