Hi all
Just wondering how often do I need to replace water pump. How many hours or years.
It’s working fine do I need to replace it if pressure is ok

Every 3 years or 300 hrs, whatever comes first. Even if you put 20 hours on the engine over 3 years, it will need to be replaced.

what musky said,

replace more often if used in sandy or dirty water

Don't rely on the outflow telltale on these high tech motors. 
Not reliable for volume or pressure flow of water through the block and rest of motor.

Can cook a $1500 water cooled EMM, $400 injector or $5000 powerhead quickly on these.
The fuel mix runs stratified charge or stoichiometric mix, take little for them to go lean burn and start melting a piston.  Need full spec water flow and pressure all the time on these.

Best bet replace complete pump with the BRP E. kit and follow the detailed instructions which are critical.  
Sandy dirty waters, more often as needed.
Best to install a water pressure sensor and digital gauge

Steel & Musky,

Not trying to be a wise guy or smart mouth here! Just adding my 2 cents to the discussion & making a statement in the form of a question here!

I've had my 3 yr. 300 hour scheduled maintenance done by my local platinum dealer who is known as very reputable & conscientious dealer... as I'm required. I've run Evinrudes & outboards for 57 years. (Ok, all maybe not so impressive by itself.)

I was going to replace my factory water pump at 3 yr. service but, my dealer didn't think it necessary yet. He knows how often and where I use my rig. It is strictly clean fresh water use. I have a pressure gauge and check my flow every use & frequently (almost obsessively) monitor my pressure gauge while in operation. I justifiably consider myself a very conscientious person. Especially, when it comes to my pride and joy Etec 90. I've had this motor since 2014.

I do not believe in taking chances with my dearly purchased retirement extravagance. Yet I've followed my dealers advice & kept my original pump in service. I am aware of the idea that it is better to be safe than sorry & generally support that!

My comment / question here is:
Since these engines are designed with the S.A.F.E. system... shouldn't this be sufficient confidence not to have to replace the pump prematurely if one watches things? The whole intent of the S.A.F.E. system design is to kick in well enough before any major damage occurs to either the electronics or mechanical parts are concerned? Or is the S.A.F.E. system software that marginal as to not be able to be trusted??? To the extent that if one watches all the pressure & visual signs... more than 3 years "routine regardless" service can be reasonable & practical???

If not... maybe Evinrudes DQR (Designed For Quality And Reliability) BRP'S corporate philosophy isn't all that??? Just my opinion about possible reasonable maintenance cost mitigation. I think I am ok for now and will replace the pump at some point beyond 3 years.

Not addressed to me - But... [wink]

An accurate Water Pressure Gauge will be your best hedge against things going sideways.  Record your pressures at each 500 rpm increment, and keep it handy.  Plastic bag wrapped on the LU?  Immediate WP drop, Stop, Reverse, and then tilt up and check.

A gradual drop will indicate time for replacement.  The water pressure itself will not help safeguard your EMM, etc. from higher temps, but many regard it as an Early Warning.  If pressure falls off for no reason, the Temps are going through the roof.  POSSIBLY too late to save your EMM.  Ouch.

Meanwhile, I wouldn't press it too much, as said above.

Just the View from Under the Shade Tree.  [biggrin]

Shady Phil

EDIT:  Yes, from 2010, but doubt that they vary too much on G1 I-3's.  Note the drop at 3,500!  Mine did exactly that and was concerned until I looked at the chart.  All is well!
