I've never seen an E-tec, including my 06 that "pees" they all just dribble lol. But mine builds some serious water pressure.

 

They make an adapter that screws into the pee-hole that redirects the water into a nozzle and shoots it out the side were you can see the stream. There was a bass boat on LOR that had the same engine 225 with the pee-shooter on it.

 

If only the impeller was changed I would definitely check the housing for heat damage. Sometimes the distortion could be extremely hard to see that is why I typically put an entire kit in when I change the impeller. Another possibility is could be the buildup of salt corrosion inside the water passages of the engine. Unless the engine is run up to operating temp while flushing the thermostats don't open so the flush will not completely remove the corrosion from the engine water passages, this acts like an insulating layer and the engine will be unable to cool at higher rpms. I like to remove the thermostats, put the covers on and with the lower unit removed hook a bilge pump to the water intake with a hose. I us a large bucket with a ten to one water to CLR mix and allow the bilge pump to pump water thru the engine from the water pickup above the lower unit for about 5 hours. Rinse with fresh water and reinstall all. This has worked when everything else I have done to rectify an overheat has failed. Make sure to properly dispose of the CLR when finished. Hope this helps... P.S. - I would not recommend modifying the overboard indicator.

 

Is that with motor running or just bilge pump

 

Look up build up buster! Also change your pressure relief spring put a lighter one in. Check to see if your pressure relief valve is under the recall for the service bulletin

 

First you need to have the engine hooked up to the Evinrude diagnostic software to see what kind of overheat condition that you have, there are 3 types - port cylinderhead, stb. cylinderhead, or EMM.

Being an '06 engine, there is also a service bulletin about overheating and it applies only to a certain serial number range. See your dealer to find out if yours is affected and if so, that it was complied with.

Regular water pump, blow off valve, thermostats, and EMM-VST cooling systems have to be serviced at regular intervals, depending on how you run the engine and in what types of conditions.

They talk about the etec high intake screens .... that might be something to consider ....

 

2006 225 etec over heating

I have a new water ibis with a 2006 225 etec on it. It has extremely low water pressure at idle speed and overheats if i go over 4000rpm. At 4000 rpm it turns about 10-12 psi. Just replaced the water pump and that didn't help. The etec dealer in south padre said it was the lightning gear case not taking the aerated water from the tunnel drive. What are my options for new gear case or anything else yall would think would work?

If you have low water pressure at idle, the gearcase intakes are submerged and that is not the problem at the moment. First the tech has to find out why the idle psi is not in the 3-5 range for a V6 E-TEC. There are one or two bulletins about overheating on those early motors, and are determined by serial number.

 

That method of cleaning with car is with a bilge pump and hose hooked to the water tube going up to powerhead and flushing for several hours. Not Running the engine. Just make sure your bucket catches the returning water. You will see lots of flaky corrosion in the bucket when you are through.

 

That was supposed to say C L R

 

If your gearcase has removable screens, they are multiple sizes available to increase flow.

 

Emm cooling ports get filled with debris and build up-take off those lines and make sure clear. Weed eater cord works as a good “pipe cleaner”.
