Engine angle to transom?

I have a 1979 Montauk hull with a 1972 Johnson 65 HP engine. It has been a while since I've owned an outboard without power trim. (Spent too many years sailing I guess) The Engine can be set at various angles to the transom with a pin. Which direction, out or in, will produce what results? Most of our use is kids waterskiing and cruising around the bay here in Erie, PA.

Out will raise bow, increase top speed, make
a bumpier ride on windchop, and if overdone,
make it porpoise. In is the reverse. I have
PTT, and I usualy run it trimmed almost all
the way for the ride.

You want the motor's cavitation plate to be more or less parallel to the bottom of the boat.
You will most likely use the second hole out from the transom for the pin.
If your options are having the motor a trimmed a bit in (gearcase closer to the transom) and trimmed a bit out (gearcase further from the transom) then you probably want it trimmed in if you are water skiing, and generally putting around.
If you are looking for the highest top speed possible than put the motor into a trimmed out position.
