can anyone ID this 650 head?

[Mouthfulloflake]

took the shell off, and sealed around the plugs with hi temp copper permatex.

does anyone know the make of this head?

I guess there is ZERO chance of finding that gasket anymore huh?

 

[Mouthfulloflake]

doh

 

[Mouthfulloflake]

bump, no one has ideas?

boat was a retired race boat, 1990 superjet.

lots of attention to detail in the initial setup, probably 15 years ago or more.

I assume this head is that vintage.

any ideas?

if no one i'd's it, we can make one bro

freaking wife forgot to sign me back in......

 

[Mouthfulloflake]

make the gasket?

I think that copper stuff will seal it, it worked well on my 15 year old re-used exhaust gaskets.

I was more curious about who made the head!

I wondered why your wife was calling me 'bro' that seemed a little wierd, even for her!

 

[ketsair]

hahaha, if you have to have the material made, we can do it, just need the thickness, which likely wouldn't be detrimental on that if it's a little thick

 

[Mouthfulloflake]

I I can measure it, but its compressed from the initial tightening.

Id likely lap both sides, and copper spray a few coats and bolt it back together.

do you have a magic gasket widget CNC machine or what>

Rogo also made the Rooster Shooter.

They are out of business.

 

[Mouthfulloflake]

I am afraid to ask about the rooster shooter, but thanks for the link on the head.

I sealed this one up (hopefully) with some permatex goo.

if not I will try again, and if that doesnt work, I will swap back to the 701 backup engine.

underlying theme here shonuff, stay away from my ski.

[Mouthfulloflake]

nah, I painted it grey and pressed it back into service.

:biggthumpup:

I might could use one of the inner gaskets, or two.

awesome info, I was told it was a mariner head too.
