Rotella oil has changed formulation?

I bought a gallon of Rotella T1. The API rating only shows C, for compression engine, I understand it used to show both C and S (spark engine). Does that mean they changed the formulation? Are you...

No when I started the engine the temperature was well above freezing so I don't think the water outlet was blocked.

Freeze damage

My boat is in fresh water. A month ago, last time I went sailing, I had left two 60 watts bulbs on in the engine compartment to prevent freezing. The other day I went back to the boat and found that...

One of them was very loose because of rot. I epoxied them back in place.
Good point. Those lags should be able to hold the engine in place upside down!

Carburetion issue, compression issue, or what?

When in gear and the throttle 3/4 open, I can cruise just under hull speed in calm water. But when I open the throttle all the way I don't hear any change in rpm. Could that be caused by fuel...

Racor fuel/water separator

My boat came with it, but I don't know how it works.
Should I loosen the bolt at the bottom periodically and discard whatever drains out of it?
