Review on Sierra International 18 3668D Marine Thermostat by Rashid Summers

Revainrating 4 out of 5

Lots of gaskets for spares

All the various gaskets and fittings you need. Used this on my 2005 Maxum 1800MX with a carbureted 4 cylinder 3.0 liter engine. After cleaning, the scale came up normally. A note: there is no plastic grommet that sits on top of the thermostat. So if you have the jack you will need to order a separate one.

Pros
  • Packing height: 4.064 cm
Cons
  • Outer
