I've got 502 Magnum EFi Gen.6 as a gift from my boss. Engine is in a bad shape and I planning to rebuild it.
Unfortunately nothing is available in my country...
Can anybody direct me to "one stop" parts supplier ? Nothing fancy, just a reasonable quality reasonable priced stuff ...
Any help will be much appreciated.

mercruiserparts.com , great service,

There really are not any full rebuild kits. You have to take it apart and determine what it needs. The factory merc parts will be way more expensive than buying them from an engine builder or hp parts supply place.

That's right, mercruiser originals are not cheap at all...
I've took engine apart allready.
Water ingress in cylinders ,some corrosion on the walls - so, I have to rebore the block. What'll be better - to go to the next oversize or straight to 4.500?
One valve is brocken (thanks God nothing with the head! ) ,I planning to change all, so, this is second position on the list...
One pushrod bent. New ones?
Full gasket kit - for sure.
New main and conrod bearings.
Circulation pump.
Electric fuel pump.

Any suggestions?
