1967 40hp evinrude no water

[cadilacboat]

I have a 1967 40 hp Evinrude. I have no water coming out of the port. I have took the lower end off and replaced the impeller also new seals on the top of the impeller housing. I took the pipes out and there are no plugs in them. I also turned the shaft and it pumped water all the way up the pipes. I poured water in the two ports where the thermostat is and water came out of them with no problem. There is no water in the cylinder that I can see. I have no compression in the top cylinder, 80 to 90 in the bottom.
Dose anyone have any thing I can do or any easy fix.

[R.Johnson]

I think the compression is the first point to look into. If it' a blown head gasket it won't circulate water.

IS it worth it taking it apart

[R.Johnson]

All you need is the head gasket.

[tx1961whaler]

If you were testing it in a barrel, the water has to be up pretty far for it to pump.

The barrel gose up to where it mount to the boat

Well i gess Ill get a head gaskit on order then thanks

[cadilacboat]

Well i got the haed gasket and took it off it dose look blowen in the two middle water jackets. I was looking at the head when i had it off and i saw pitting the the cylender that was blown wat is this caused from and is it going to be a problem

[R.Johnson]

The pitting will probably be in the aluminum casting, not the cylinder sleeve. If not to severe, I would'nt worry about it. Can you post a picture?

[cadilacboat]

yes hold on

[cadilacboat]

there to big for an attachment is there any way you can pm me an email so i can send them

[cadilacboat]

I have just replaced the head gaskit there is still no water still no comression in the top cylender. I think I have more problems . Am i looking to throw it away or is it easy to fix? Is ther anything i can check test.
