Evinrude te60tlene 92 60hp miss

[Chrisham]

buddy of mine is having problems with this motor.cleaned carbs new fuel tried 2 different tanks took coils off running motor no different compression 98 96 92 new plugs could this need a head gasket this compression seems low with my guage

 

[flyingscott]

Get different gauge to double check. That compression is horrible. Of.the second gauge reads the same.pull the head

 

[jakedaawg]

I'll second that assessment if it helps...

 

[Chrisham]

I used the same gauge on a 93 25 it read 120 both cylinders

 

[flyingscott]

If you are confident in your gauge pull the head.

 

[Chrisham]

We are going to pull the head must be scored cylinders could the head gasket be the culprit also

 

[boobie]

Do a cylinder drop test on it to see which cylinder is bad..

 

[Chrisham]

What is a cylinder drop test

 

[flyingscott]

I would usually agree with boobie but not this time. Your compression is bad enough to look at that first. Yes a head gasket can fail.but usually not on all 3. Time to pull the head.

 

[Chrisham]

Is this running it with . Plug wire removed.what would cause this low a compression on all cylinders just a wore out motor

 

[flyingscott]

Do.you have all the plugs out when you are doing a compression test. could be anything a bad gauge, bad head gasket or motor not turning fast enough. Or the motor is worn out I am not there. A head gasket costs around $20 cheap enough for a look see.

 

[Chrisham]

Definitely going to pull the head . when checking compression I just pull one plug at a time.Isnt this how you are supposed to check it

 

[flyingscott]

No you pull all the plugs out for a compression test. You need it to spin as fast as possible. Pull the safety lanyard off to kill spark and run another test with all the plugs out.

 

[boobie]

Maybe I missed it, but how's this thing run ? What's the complaint ??

 

[Chrisham]

Missing bad at high speed somewhat just poking around

 

[boobie]

Maybe you have some ignition problems ??

 

[Chrisham]

Checked compression with kill switch pulled and all plugs removed 109 top 96 middle 92 bottom time to pull head

 

[Chrisham]

my buddy took the head off today.He said cylinders looked good,no scoring.He said head gasket did not look blower around the cylinders.There were some disruptions around the water jackets but I don't see where this would effect anything.I am not sure he or I know what to look for.The only scored cylinders I have seen were on a chainsaw and it was obvious.

Read post # 16 again.

 

[Chrisham]

Took the head gasket to the local marine mechanic.He said sounded like a fuel issue.he said check for an ignition miss with a timing light
