Reply To: Installing a telltale

[amuller]

One obvious issue here is to keep the telltale volume as low as possible, low enough so as not to seriously disturb the cooling water flows. At the same time, we don’t want an orifice so small it will routinely clog. Anybody have numbers?

How do we understand OMC producing motors without thermostats, such as the “33” hp skitwins, etc.? It seems these would be over-cooled most of the time…..
