  • thermostats

    i have twin outboards 225 hp ox 66 yamaha 1998 engines

    Is there a special technique or method for installing thermostats?

    drfish,
    Take a look at the diagram for your motor in the online catalog (above). Look under "Cylinder Crankcase 1". Each thermostat is under the thermo cover that is held in place by two bolts. You will need two new gaskets to go with the thermostats. Should be pretty easy to replace.
    Good luck [img]smile.gif[/img] ,
