On average, or as a range, how much should one expect to pay, per motor, for a top-end refresh on a 500EFI?

Yes they were all set-up to spin in from factory to get more lift. Makes backing up much more difficult can't just use sticks as with most twins.

Ok now i have noticed on a lot of big powered boats there seems to be a water dump out the on the sides or back of the hull for the motors. On my boat the holes are there for it but nothing is hooked up to them. I have the 500 efi's and i was wondering douse my power package not need it or is it something i should look in to hooking up?

I wouldn't say ALL boats were setup to spin in. It depends on the boat, x-dimension, drives, etc. Not ALL boats are the same.

Top End is complete and engines are back in the boat. What the engine builder told me was that the head gaskets were shot and I wouldn't have gotten another season out of them, he also said that he tested all the valve springs and could find one that was within spec, all were weak, none were broke or cracked though. This was all done with 292 hours and easy hours in my opinion. So if you run your boat hard or do a lot of poker runs I'd be looking to tear into things sooner than I did.
