Force 125 thermostat o-ring part number?

[Glastron Boater]

Hey guys, I'm getting really close to have this boat running. I got the system back flushed, lower unit back on with new water pump impeller.

just got the thermostat and gasket in the mail, but it didn't come with the thermostat O-RING like the one I pulled out...

Does anyone know a part number I can look for here or possibly have my auto parts store cross reference?

I looked here on iboats and all I found was the thermostat and the gasket, but no O-RING.


Thanks in advance.

What year is your Force? I looked up 2 and they were different.

The grommet can be found all over the place.
Crowley wants way too much.

This site sells it for under $8.

Mine I believe is an 87.
