PSI @ Zero. Peeping out front of lower unit?

[LA3]

I just bought the boat. It has 1991 c115.<br />Changed impeller. Everything seem to line and<br />put back right. Peep stream GREAT. Increase and decreases with RPM on hose.<br /><br />But, PSI gauge does not move.<br />And there is water pouring out of peep hole in<br />front of the lower unit? why is that?

Re: PSI @ Zero. Peeping out front of lower unit?

did you check the pressure valve grommet and t-stats? and blow on the hose leading to the guage and see if it moves.<br /> the pee stream really should not noticably change with RPM. at idle it should dig holes in concrete. if it does not you have a pressure loss someplace.

Did you use a sealant on the pump housing to hold oring in when you repalced the impellor?

Did not use sealant.<br />Took white/clear hose off the brass fitting on<br />top of cyc. head. Tried to blow air into it.<br />Gauge did not move.<br />Some water with air bulbs were in the hose.<br /><br />I had the motor trimed all the way up and slide the housing on nice and easy. O ring slided first time. But sat nice the second time.

And where is pressure valve grommet?<br />Is it where I took the hose off?<br />Because that was clear and clean into the head.
