fit perfectly. just didn't have the seal that goes around the metal rim. however the original seal was still good so that wasn't a problem.

Q:
Are there gaskets that need to be replaced whe we replace the thermostat?
A:
There are thermostat kits available, depending on your make and model, that do include gaskets. We do recommend purchasing replacement gaskets as well, if you do not already have spares.
Q:
Do you have a t-stat for a 9.9 ob, 105 degrees?
A:
We can only match it up by make and year as well. We would also need a model number to see if we can cross reference the OEM number. Call us at the number at the top of the page and we can assist you further.
