I am not near my boat to measure at the moment but would like to get a spare thermostat. The engine
is a Yanmar
I believe the part number is 129470-49801, it is a bypass type rated at 76.5°C and I think offset but I would prefer not to pay the Yanmar price
So has anyone out there got one that they can measure for me?
If so I need the following info:
1) The diameter of the main body disk.
2) The diameter of the bypass valve disk.
3) The overall height between the two disks when cold/closed.
There should be an aftermarket alternative available I hope.
I have attached a photo
of a bypass thermostat to hopefully help with a reference.
Thanks in advance.
