2007 E-Tec low water pressure

I have a 2007 220 HO E-Tec with low water pressure.  The water pump and housing has been replaced by dealer.  Water pressure is zero at idle, and only get up to about 12 when on plane.  Also, computer read out says the motor over heated about 50 hours ago.

 

I'm concern about over heating engine computer.  Any ideas?

Low water pressure can also be caused by stuck open thermostats and a sticking or debris jammed pressure relief valve.

Of course, incorrectly installed water pumps can do the same.

 

Was a complete #5001595 pump kit installed or just an impeller?

 

It also may be a good idea to check your gauge to be sure it is accurate.

Re: 2007 E-Tec low water pressure

I replaced the water screens with a high flow screen (Part number 0-5007081)  this corrected the issue.  My old 2005 e-tec had the same issue.  However, it never got hot enough to cause a problem.

 

Thank you for you advise.

Is the water pressure still at zero at idle?

Yes.  However, I have a strong stream of water coming out the indicator tube.  Also, my gauge still shows 12 while on plane.

It appears then that you still have low pressure or a questionable gauge and changing the pickup screens did not improve anything from what you are telling us.

Re: 2007 E-Tec low water pressure

The pressure stream that comes from the indicator tube went from very low force to a much higher force.  Doesen't that mean I have higher pressure?  What should the pressure be?  Can I test the pressure at one of the hoses on the engine?

Remove the water pressure fitting on the engine block and temporarily hook up a known accurate pressure gauge and monitor the readings every 1000 rpm plus full throttle and dead idle.

 

Idle should be in the 3-5 psi range

 

Then post the other readings here and know which gearcase you have on the motor if it is not the original one.

Re: 2007 E-Tec low water pressure

I cured low water pressure readings on a boat by removing the water pressure tube from the engine and gauge then blowing air through it. Had some green algae come out of the tube.
