In an effort to ease summer heat fade....I swapped my oem thermo for a 158* merc....years ago. Somethin like $48.
Remove end hose.Take a 2qt pitcher of as close to boiling water as you can stand. Slowly pour it over the thermo housing. With large channel locks...slowly turn end cap. It will pop off. It goes back on easier than it comes off. Some have used a worm clamp to reapply pressure on the housing at the cap after it's been replaced. I did.

It is a Merc Marine thermostat....158*...or so I always thought. Maybe it was a 160*...all the old threads are gone...couldn't find it on the board.
I'm sure there's more than one old timer here with a better memory than mine.
Your lucky day....
Since nuthin was wrong with my oem thermo I stuck it in the wrapper of the then new 160* Mercruiser thermostat.
replaces 99155A1 160*
made in Canada
