This is what the cooling system is now, its a new motor so Im not sure what it orginally had on it.

This is how it was.

Thats a raw water system, No restictor plate under risers ans as far as the therm. cover gasket it looks like the round cork type in the 1995 parts breakdown. System II design part#27-80671 The therm base gasket is # 27-530451

If your therm. cover gasket has the two bolt holes then you need the gasket with the small square section blocked.

Looks like your cover is this style but not open like the pic. The area circled will be blocked for your system part # 27-41812 The one in the pic is for a closed system which your's isn't.
