Hi, can anyone tell me what the operating temperature should be at WOT for a 2008 75hp Mercury Optimax .
You may be able to find the best answer on the Mercury Outboard Forum.

Remove the plugs and blow them off and blow the cylinders out. When there is no fuel the oil injection keeps pumping the opti oil into the cylinders and can cause a hydrolock but it wont fire. Dry all of that out and you can even spray carb clean in the cylinders and blow them out to dry things up in there. When it starts it will probably smoke pretty bad for a minute but it will even out within a couple of minutes.

You should drain your oil tank and check your sender to see if it is stuck or if the pick up is plugged.

There are lots of deals on line for better prices, get exact model and year. Have a pro marine tech install it, because of liability and no loss of money out of your pocket.
