Anyone ever have problems with their new thermostats
Im on my second new Quicksilver 140 degree thermostat and no luck. They were both stamped 140
My engine will run around 155-160 then cycle up to 180 with these, first one only up to 170. Running it without a thermostat it holds 110
I even tested them in a pan of boiling water with a thermometer and they both just start to crack in the 150's
Should the stat be fully open at 140? or just cracking at 140
Not sure what I should do now.

OK, now do you still have your old thermostat, or did you toss it? Did you put your old stat in, or was it there when you bought the boat?

Do a search, there are several good threads discussing this. Check in the technical forum.

In the pan my old one starts to crack sooner then the new ones. Quite a difference in opening from old to new with the pan tempature in the 150 range. Old is definately open more. Maybe because the spring is more worn out, not sure.
I had the motor rebuilt so I was putting a new one in. Trying to keep the temp around 140
Last year with the old one in it would run in the 150-160 temp range.

Yep, that's what I was getting at. I replaced mine with new ones and had the same oscillating temps. If he still has his old one he can take a look and check to see it it has the holes.

Still not making sense watching them in a pan not opening up till way past 140
