Blown headgasket?

I have a chance to buy an '88 Evinrude VRO 150 with a blown headgasket. I'm not familar with 2-stroke motors, the question I have is about he headgasket on a 2-stroke.

Is it the same as on a 4-stroke? I mean is there anything inpaticular that will cause a headgasket to blow on a 2s than a 4s motor? If it's not worth replacing the headgasket I can always use it for parts on my 150 Johnny.
 
Easy fix and no need to remove any other stuff. Leave t-stats and sensors in head.
Now why did it blow it? Lots of things sold as "great condition, all it needs is a head gasket".
Get it real cheap or with a return guarantee if it's not what it's advertised to be.
 
Not sure why it blew right now. The add says that they have the gasket and manual, just hasn't been installed. They are asking $500 OBO but I offered $400.
 
This to replace the thermostats and sensors.
The 24, 1/4" bolts (7/16 socket head).

If just changing the head gasket, no need to remove them.
The other 14 bolts hold the head in place (don't remember the size, looks like 3/8" with a 9/16 socket head).
Be sure and take pictures if you get it and please ask questions when repairing.
 
Just got back after picking up the motor. It sounds like this has happened to the motor twice. The guy said that it happened before but he can't remember which side. What if I pulled a head of my '82 Johnson and put it on the '88 Evinrude?

The motor is a '88 VRO, so the wiring does not match my boat. Now I have two questions, 1st - how hard is it to convert over the wiring to fit the '82 wiring that I have now? 2nd - where can I find the complete control wiring to convert the boat over to the late model wiring?

If I can remember when I start tearing the motor down I'll take pics.
 
I forgot, does anyone have any information for the VRO setup, where the oil tank goes, how to set up a non-VRO for VRO?
 
Spare is saying premix your fuel and dont even bother with trying to hook the VRO back up (his fingers were a little loose on the keyboard, he meant to say TRASH)
 
you have two choices here 1. fix the head gasket and run the boat with no VRO

2. throw the motor in the trash now and do nothing! Cause when the VRO sh!ts the bed you will throw all in the trash anyway, and its cheaper to just do it now!
 
Right now I plan on swapping the power head from one to the other. My Johnson runs but has problems with the lower section. The Evinrude, like I said, has a blown head gasket. So I'm making one good unit from two so-so assemblies.
 
as i remember you can't even swap those 2 powerheads as they have different midsections and different powerhead adapters, plus you wouldn't take the wiring off one to the other as they will not inter change. the red plug is the only thing those 2 motors have in common.
 
The wiring on the Evinrude is trashed. I was planning on using the Johnson power head on the other mid section. I'll take a look in the repair manual and see if the power heads will swap.

So far they look the same, bolt pattern that is. I haven't gottne the Johnson power head off yet.
 
Look closely at the water jackets on the block and head to make sure there is not a leak on one or the other, it will be evident by discoloration different than the majority of the locations on the gasket.
See if they use the same carburetors also.

Looking up part numbers, it looks like they will swap over. The only way I will know is when I get both power heads ready to swap.

a repair manual will not tell you swap years lol, sounds like a FrankenMotor is being attempted

I did some part number crosses at the following site: http://shop.evinrude.com/ Everything I could make out says that they will swap over. If the power head will not swap then the adapters below the power head between the mid and power sections can be swapped. I'll have to do that to make it work.
