2006 225 evirude etecs on 28ft hydrasport- 375 hrs - overheat problems with port engine @ planning speed. over 60 days @ certified evinrude mechanics shop !!!! - they have tried EVERYTHING !!! changed water pump and housing 2 times, removed transom mounted transducers, installed "scoops" on intakes, new lower temp thermostats, removed powerhead to look for blockage, removed heads to look for blockage, removed "low speed diaphram" on top of emm, adjusted engine "toe", and swapped lower units, (port engine still ran hot, but did not go into overheat shutdown, i had them put the lower units back as evinrude designed them, overheat immediatly came ******.
boat runs @ normal temp @ idle and slow speeds, 1 minutes into planning speeds (less than 1 mile on plane), the overheat alarm goes off and the engine goes into "safe mode" and slows down by itself. after idling for 2 minutes, the motor has colled down, and the process can be repeated - every time.
there have been a variety of other evinrude issues crop up, and get resolved during the 60 days - these all with port engine (the one overheating): bad shifter part in lower unit, blown gears in lower unit, adjust shift cable, blown prop hub, replace coroded thermostats, replace neutral saftey switch. then, in the stbd engine we had a bad computer, bad oil pump, and a "missing" gasket - that caused 4 prop hubs to blow.
for some reason, i dont think this is normal? or is it? i can tell you first hand that evinrude, and the extended warranty company could both care less about the issues.
the problems are not the mechanics shop, as this work has been split between 2 shops !!!! with the second redoing some of the work by the first shop.
if there is someone out there that could help with some advise, i could use some.
First install water pressure guages, at least then you can see exactly when it drops out.
then you can experiment with trim settings and see what happens.
Compare it to the other lower unit when you swap them, ect.
Have you owned this boat and ran it for 375 hours with no issues and then something triggered this problem, or it just started one day?
Is this a repower with older motors, that have just been installed on the boat?
Is there anything on the hull, like a transducer or high speed water pickup thats inline with the port motor?
Have you tried to lower the motors to see what happens?
Shooting in the dark here..............Are you lean on fuel or oil ? and are the plugs fresh and indext correctly ?

Is your boat on a trailer? If so, take it somewhere else....sounds like the first shop hosed you and screwed some stuff up...overheating issues can be a nightmare, but a good technician can shorten the time in the shop....it seems you've done everything on the list, I'm thinking like welder, possible lean issue....what are you using for oil?...I wonder if it could possibly be too lean on the oil injection?...that would definently heat it up at higher rpm's....
Is there a range while it's on plane, or does it do it at all speeds on plane?
This will sound WAY off the wall. Duf on whalercentral had a similar problem with multiple trips to the dealer under warranty. After a LOT of hair pulling, turned out to be some sort of "O" ring I think on the flushing attachment. You can go to whalercentral and do a search and you will find it.
Let us know.

Another off the wall thing to check would be any transom mounted transducer. I had someone step on one and it was angled down pretty good. The wave created by the transducer was right at the water pickup on the lower unit. Everything was fine until a minute or so of running on plane then it would heat up.
thnaks for the suggestions. already have pressure gauges. they read the same on both engines. there is plenty of pressure when it overheats, same as the other engine.
boat is a 2000, was repowered with new etecs @ end of 05, everything ran great for the first 300 hrs.
transom mount transducers were removed @ demand of evinrude local guru, he was screaming "dirty water". it made no difference.
did not try to lower engines, everything was fine until reciently, will suggest to mechanics, who are completely bewildered.

boat has floscan fuel flow system, shows the overheating engine as using 2x fuel as normal engine, mechanics feel that is reading wrong, as laptop running evinrude software says my gauge is wrong.
would evinrude software show a lean oil or fuel condition?
again, will ask mechanics to check asap. according to them plugs look fine.
Back in the day....you would mark the cylinder with different types of a wax that have different melting points then run the boat...it would reveal what temp the engine is running....I'll bet that it's not really running hot but is thrown into the loop by an electrical glitch.....just a thought....you could also run the boat and take both cowls off immediately and check the temps with a temp gun....worth a try...good luck....
And what the hell are you doing to your engine to cause all those mechanical problems?
evinrude software agrees with my gauges, and i belive the sensor was already replaced, just in case.
the boat gets used 2 or 3 times per month in south florida, kept on a dry storage rack. mostly offshore fishing for sailfish and dolfin, some trips to keys for diving and snorkle.

i use only evinrude oil, and overheat happens at planning speed, even if its slow (3700 rpm)
we did have to replace an oil pump on the other engine, how do i tell if the oil is lean?

we have the evinrude software on laptop connected straight to engine, it agrees with gauges on boat. when overheat happens we see steam from the engine, where the other engine never has steam, but will try the heat gun on next seatrail

i baby the boat, dont run very hard.
The evinrude software and guage would likely read off the same sensor.
Although on some engines, the temperature guage on the boat is connected to a single wire temp sensor and the ECM / computer is connected to a two wire sensor.
My buddy had the exact same overheating problem on his 225 e-tec.He had it back to the dealer 3 times and they could not find anything wrong.
They finianly put in larger diameter water lines and so far so good.
Next time I talk to him I'll get more details for you.
Look at the hose connection that connects to the outlet hole. Mine was attached with a zip tie and was causing the engine to overheat. I hope you get it solved. I am so glad I do not have the E-tec anymore.

That's a band-aid fix. That's not a proper repair. The problem is still there, it's just being hidden.
Barring extenuating circumstances, the mechanic should not have to modify the existing system to make it work.
That's like saying will my 10amp fuse keeps blowing, so I put a 30amp fuse in it and it's fine now.
Desperate for help with evinrude etec overheat
