This was previously posted with no replies. I hhave decided to repost and rephrase:
Engine is a 5.7 1994 Mercruiser S//N OF353346, (recently overhauled).
The original thermostat housing was corroded and has been replaced with Mercruiser part # 87290A23 as per Service bulletin 99-2.
I have researched the threads and find contrary advice as to how to set the check balls. From tight to loose... Any reference to a Mercruiser Manual? I have them all and can find no reference as to how to calibrate...
Also can I replace the riser gasket from "two large/two small slots" to "four large"
Experts out there please input
