Water Pump Indicator (Water not appearing out the back of the motor)

[ Edited ]

Hi There,

 

I have a 2006 75hp Evinrude eTec motor and it is not sending water out the rear hole in the motor which indicates the system is cooling correctly.  Embarrasingly, I learned this only after driving the boat for a period of time - during this time there was no issue with overheating, no rpm dropping, no horn, no nothing.  The motor runs great, so I don't suspect it has overheated.

 

having said this, I'm very concerned and took the casing off to inspect the hose the water is supposed to come from to ensure it had not become dislodged and it is fine.  I'd read that this was a common problem.  I also verified it is not plugged with debris.

 

At this point, I'm stumped.  Does anyone have any ideas what the problem might be?  Is the water pump dead?

 

Thank you.

  Hi Doug,

 

The overboard water indicator does not cool the engine as such, but it does provide cooling for the engine computer (EMM) and fuel vapor separator tank (VST) as well as being the tell-tale.

 

Chances are you picked up some weeds, mud, sand, etc. which plugged up the smaller diameter hoses and fittings on the engine that connect to the EMM and the VST. A broken or disconnected hose can give the same symptoms but you would find water spraying inside the motor cover.

 

Do not run the motor until repaired  and the water flow restored. See your dealer.

Hey Bill,

 

thank you for the response.  That's something of a relief.

 

Funds are a little tight - is this something I could look over myself or do you highly recommend taking it to the dealer.  If so, I'll bite the bullet - any ideas what the approx. hours to look at this should be?

 

Thanks again.

I do not know your abilities, but you might trace the water lines that attach to the engine computer and the vapor separator tank. Do not use compressed air, just blow through them to make sure they are clear. If you reattach the lines, use the correct "ty-rap" that has the radius on the head to make for a good clamping action around the hose - part number 320107.

Hey there,

 

I'm fairly fluent in basic mechanics, so maybe I'll take a shot.  I did previously try blowing into the water exit (pee) tube and I couldn't get any air through it so based on what you are saying, sounds like it's plugged.

 

I'll report back with my findings.

 

Thank you.

I Doug, just wondering what you found to be the root cause of your issue. I have a 50 HP etec that is doing the same thing. I replaced the impeller, bypassed the thermostat, checked all the hoses for blockage and still have the issue. Very little water coming out of the tell-tale exit hole.

Mark,
Doug's question was 5 years ago. Check the date.

On yours, if the flow is weak, inspect the fittings, hoses, and the vapor separator as well as the EMM passageway for a water restriction.
