I have a newly acquired to me Johnson Fast Strike 150. On the test ride I noticed the water gauge only reading approx 7.5 psi. This is my first boat with a water gauge and researching on hear it seems it should be around 20 PSI at WOT. Is this correct?
I ran it for a minute on the ears and noticed that water was only coming out of the small pee hole (at a pretty strong stream) and none from the square ports on either side of the small port. Is this normal?
As a precaution I want to replace the pump. Should I use OEM parts or are the aftermarket pumps ok? Does anyone have a OEM p/n for the pump? I found several different numbers online.
Thanks for any help you can provide.
I think this is a 1993 model?
