Water pump replaced but now this!

[ford84]

So I got the water pump replaced in my "Tracker" Mercury 60 ELPTO 2004 2 stroke taking it apart was interested and I also was going to replace the thermostat which some people told me not to do or worry about. Well after getting to the old water pump and impeller this is what I found



So we ordered the new kit and replaced everything to do with the water pump.



Wasn't really that big of a deal either went smoothly the biggest PIA was putting the lower unit back in to the outboard. But it started right up....there was a pee stream of water...buuuuuuuuuut it was more of a trickle.....so I thought well lets see whats in the thermostat and replace that.





It was all gunked up and there was even some parts in there just sitting around that I scraped out. So I replaced the thermostat and the gaskets as well. Put everything back to gather and yeah.....still not all that great. No change really, while it was running though I noticed water coming out of there places and I am not sure if this is normal because well my first outboard.

As you can see here circled in red the hole its coming out of and then water coming out of it.





Also there was a spot on the lower right next to one of the bolts where it would come out as well....this one is harder to see because well picture of moving water right. But I am also going to post videos. Right in the middle of the red circle you can see a uniform stream of water coming down the hole it comes out of seems to belong there its not a crack or anything and they are both machined holes.



So I was told by oldboat1 to flush out from the thermostat, did that as well.


Also gave some advice and help as well and I am still struggling with this.

Here are the videos of the motor running.

Didn't see a vid, only hear the sound of the motor.
Seeing all the pieces from the impeller clogging up the thermostat, it could also be clogging up the pee hole

 

[ford84]

Yeah I am actually on my way to my buddies house now and going to pull that off and see...we pushed something in there while it was running and had no change but it wasn't a very long item. I am going to trouble shoot this with out going to a marina! I appreciate everyones help in advance. I don't know why the videos won't show either.

Deleted the 2 extra Photobucket video posts since the Youtube vids are working.

Somebody ran the the motor dry and the shredded impeller is the result. All the junk in the thermostat is impeller bits and there may be more scattered through the motor.

Did you check the water tube for blockage? The water leaking around the lower unit could be from water getting past the upper water tube seal where it enters the powerhead.

 

[ford84]

Pulling the tube off in about 15 minutes here had to run and get some zip ties....Is there a way to check if water is getting past the upper tube seal and replace that if needed....I feel as if that is a huge headache and I really don't want to go into removing the power head if I don't have to. Also thank you for deleting the post of the extra videos.

 

[GA_Boater]

Water is making it into the powerhead - the tell tell is working.

Find the end of the tell tell on the motor end and pull it off. Put the muffs on and see how the water is flowing with that end of the hose removed. You can run some heavy fishing line or weed whacker line in the hose to clear it.

I don't know how to actually tell if the upper seal is leaking, but with the tube off you may be able to look for chunks in that area. Yeah, the ability to stand on your head helps. :smile:

 

[ford84]

So got everything flushed out and boom!!!

Wish I could pee like that again :facepalm:

There ya go.

Did you find any rubber bits in the driveway?

 

[bruceb58]

Did you ever start your engine without water?

After finding my thermostat stuck open in my 2006 90HP Mercury, I am going to change out my thermostat on a regular basis.

 

[BWR1953]

I can't tell from the video. Is there water coming out of the front of the lower unit?

+1......

You or the PO ran that engine for an extended period with no cooling water supplied. The rubber just ground itself off against the SS pump housing since there was no cooling nor lubrication (from the water). On the TSTAT, bad advise given not to have look at it, especially when you have a 12 year old engine. Obviously you were wise to check it when you saw the impeller.

Can't make much from your pictures on water leaks. Water exits several places normally. The tell tale runs off the exhaust manifold in most of those engines and water is supplied to that continuously, regardless of the temperature in the powerhead cooling water. If you are concerned about volume of water, remove the ⅛" plastic pipe ell at the manifold cover plate while the engine is running on muffs and clean it out with a wire. Then reverse blow through the hose with compressed air before you put it back together.

Looks fine to me. The junk in your thermostat were chunks of your rubber blades off your water pump. Plus your motor having a thermostat running off a cold hose doesn't open up all the way. You get it in the water get it warmed up and under a load it'll be pushing more out the pisser. The holes are there just so water doesn't sit in your exhaust housing and freeze.

Thermostats work fine even on a hose. When my thermostat was stuck open, it would get to 90 on the hose and 135 after I replaced the thermostat while on the hose.

BTW, when you quote people, remove the pictures.

 

[ford84]

There ya go.

Did you find any rubber bits in the driveway?

GA_Boater Yeah there was little rubber bits all over the place, thankfully we were able to clean the new thermostat out since some little bits got stuck in there too! Still trying to figure out if the water coming out of those other 2 holes is normal. Gotta go to the marina soon anyways so just going to ask them.

bruceb58 We purchased the boat with out the tell tale showing water....we were told that all maintenance was done on the boat and everything was working fine a few days prior....the guy also had the hose used to flush the motor while running it hooked up to his hot water heater, the temp on that water was enough to open there thermostat from a cold start.

Yeah...don't ever do that. The motor will have the thermostat open within a couple minutes. That's a good way to overheat the motor.

If it's plumbed like it's bigger brother (90 triple) the stat has nothing to do with it. Water comes directly from the exhaust manifold cover and that isn't in the tstat circuit. Will agree on more water on the water as water pressure and higher rpms will increase the volume/pressure of the pump output.

On "burning up an engine with 140F water (US domestic hot water heater Normal setting) from a hot water heater":

That's the pellet temp stamp number (143F) aka opening temp of the stat. The OT sensor is set to 195F. Sitting on the driveway at low rpms with no load will not generate enough heat to light off the OT sensor unless you forget to turn the water on. That answer is based upon my not being able to keep my stat open continuously on muffs in the summer, monitored with a non-contact infrared meter.
