What where your oil temps last year?
What is your current engine temp?
As a rule of thumb you usually replace the housing and plate on the seawater pump. Its not that much more. If you have good pressure you will be fine.

I run my engines at 135-140 coolant just for the purpose of keeping the oil temps under 230f. I've done everything imaginable to get the oil temps right, but this is the only thing that made it so I can run hard for long periods of time. I used to be like you. 30 second shot then crack the hatch and let the oil temp drop. I even wiped out the mains on the sb engine one summer when I let temps get up to and over 300f. I have had no ill affects from running my engines at this coolant temp. They look great inside. This will be my 3rd summer running on this build and with the coolant and oil temps inline.

I had a circ pump fail, and it had roughly the same effect.

Look up your motor here and then click on thermostat or cooling when you get that far. They have the exploded views of the original merc manuals.
