Evinrude outboard Motor overheats any suggestions?

Question

I have a 185hp outboard that constantly overheats! I just had the waterpump, and thermostats replaced. I have even taken out the themostats, and loosened the covers to see if water was getting up the upper half. She is pumping water up to the thermostats, but after about 15 minutes at idle, no more water just steam! I'm on a bugdet, so I can't afford to take it to a shop, please help!

Answer 1

I would go back to whoever serviced it. They should have test ran it to make sure it was ok. I think they owe you a diagnosis and a fix. That is poor work on their part. Take it back.

Answer 2

First thing is did they replace the water-pump housing when they did the job or just the impeller?If only the impeller the housing could be melted and this would cause your problem.

Next is there could be a piece of the old impeller stuck in the housing or somewhere else.You must removed your lower unit and check for this because there is nothing else that would cause your problem.Good luck.

Answer 3

ouch, that sounds odd

my first suggestion would have been the water pump, when it is running is a stream of water coming out the pee hole?

(there is another name but I forget it)

do you have compressed air available? I have sometimes found that backflushing the water system helps, blowing air throught the water system from the outlet hose so if there is anything blocking the system it might be forced back out.

If you dont have air available, you can do it with a hose and backflush with water, just bit messier is all.

that's all that comes to mind at the moment, good luck with it.

Head gasket leaking into the cooling system

Exhaust gasket leaking into the cooling system

Do a compression check all cyc>For head gaskets>
