Default 3.0L merc efi

i started my 23cc project. nothing special yet just taking out the wireing and stripping the console. ill have porn of that when i get started on the console. i bought this boat knowing the motor had a bad hole in it. well it was killing me to not know what it looked like in there so i took the head off last night.
what i want to know is, is it cost effective to rebuild a 3.0? whats the best way to do it? bore out all cylinders and put oversize pistons? (im leaning towards that.) i think this motor had an oil injection problem because all the cylinders have a problem. anyone who has taken this on please give me your opinion. im not afraid of rebuilding it and ive got the tools to do it.


this is the hole with 0 psi:


the rest of the holes have about 100 psi and look like this:


how much does it cost to get a block bored??
thanks for any input guys!!!
