As soon as you get the boat I would .....

1. Change motor oil
2. Change gear oil
3. Change impellor.

This way you have some kind of maint. baseline. Those 3 things are pretty easy to do yourself.

You said your Temps are getting up there, do you know if there is a separate water pick up for your inner cooler, or is it one pick up teed off?

i dont think it has a seperate pickup for the intercooler. could this be a problem?

If the one pick up is feeding the inner cooler and the motor it could be, the water is going to take the path of less resistance, which would rob your motor. Just a guess, I have a whipple as well and I had to reduce the water going into the cooler so my motor would get more water flow. What kind of whipple set up do you have?
