500hp carbed thermostats
I bought this boat used 3 years ago from an estate where the owner died so I have no references.
I went to change my thermostats and was surprised at what I saw on the previous ones. When I popped the top cover the thermostats were sitting right there on top of the sleeve. I checked the parts diagrams for the 500 and it showed what I was used to seeing in my previous engines- thermostat goes down in the housing, then gasket, then sleeve and then top cover.
Can someone with experience enlighten me as to the proper install?
