The deflectors are just about the only thing left..... when you change them you will need new head gaskets too. I did it all on my V-4 and have zero issues

I can hold my hand on the cylinder head for a count of 3 maybe 4, and it is not overheating. Invest in one of those cheap infra-red thermomiters and check the actual temp. You may not have a problem at all, just not very tough hands.

Re: evinrude 115 84 overheat

When you replaced the thermostats, did you check the valve body inside the thermostat housing? It has (depending on year) two pinholes or a single oval hole. These holes pass a small amount of water to the back of the stats to tell them when to open. If this/these hole(s) are plugged up (a common problem,) you can get still get an overheat.

the valve body is brand new .

You could take off one of the head covers (not the head) and have a look inside at the condition of the cooling passages inside the head. Look for any water flow restrictions. What you see inside these heads may be the same as what is inside the rest of the block.
