Water Pressure for Honda 150 HP

Senior Ron · Nov 21, 2017

Can anyone tell me what the normal operating Water Pressure should be for a Honda O/B 150 HP.?

Thanks, Ron

If the manual does,t specify anything i would measure the poppet valve spring tension with a spring gauge and compress the spring +/- 5mm down from its original length from the gauge reading i will work out the pressure when the motor is at WOT then work back from that reading.
