Closed deck



Open deck, this particular one used to be very similar to your v8

Thanks for the pictures. I understand now. When I think of a closed deck I was thinking more like the Mercury motors without heads where you have to put pistons in through the bottom.

Nope, the top pic is obviously a 60* they do not use gaskets they use O-rings but its still a closed deck motor

Ralph was not asking about V8's re-read his post, all the pics I posted were OMC's

Here is a ~99-01 closed deck 90* V6 and no theres no head gasket on it
