As to outdrives. Given the cost of the boat you are comtemplating you
should consider changing marinas if the depth of your marina will not
allow
you to use a conventionally propped boat.

Check the thread. It's his own pier on Kent Island.

But regardless of which type of drive, you're going to be hard-pressed to
keep anything over 30' in three feet of water. Jet drive boats like the
Hinckley's being the exception, but prepare for sticker shock.

I think you'll find that a boat
of that size will be very difficult to sell on the used market when the
time
for that inevitably comes.

Diesel in boats over 34' certainly do seem to sell faster on the used
market. I wouldn't go so far as calling it 'difficult' to sell a larger gas
powered boat. But when you get into the 37' and up range you really do
benefit from the torque the diesels have to offer.
