Don't wish to be repetitive, here are my three suggestions:
In the order of importance----
1) dump that wimpy oil cooler and install the largest, non-chrome cooler that you can find.
Reason: 600 + ci w/wet sump oiling
2) disconnect the outdrive water pick-up point at the inner transom plate. Install a thru transom water pick-up
Reason: com'on, 700-800 hp and your still using the Merc water pick-up system?????????? Can you say restrictive!!!!
3) remove the crossover and install a water recir pump w/ a t-stat and water by-pass hose.
Reason: Puts your motor in control of the water flow and temp thru the motor. Hey, look at Merc racing motors and see what they use.
#1 and 2 are a must. #3 is optional.
FYI: The Keith Eickert oil thermo unit has the internal valve "open" for oil cooling set at 215-218 degree's.
