I have a mid 70's merc 888 in a 24' Zeta cuddy cabin. Due to partial to complete retardedness on my part, the engine is just back from the rebuilders today. I sent him the block with rotating assembly as well as the heads still attached. He checked and bored the block to .060 over (it was already at .040 over from previous rebuild), checked and serviced the heads, and put a new marine cam in, as well as new core plugs, oil pump, lifters, bearings, other things normally done as well. He put a new balancer on the original crank, and I have been reading that the older 302 fords had lighter balancers than the newer ones. Is there an easy way to confirm that the correct balancer is on the crank ? I can't imagine the rebuilder would have made a mistake like that, but who knows ?
Also, what to people normally do for engine break in in a boat ? The rebuilder said to take it easy and modulate the rpm for the first few hours, i.e. don't run the boat up on plane for hours on end, and don't troll along all day, so I suppose I'll have to take a couple days on the water and run the boat like that, instead of how I normally run.
The engine has a closed cooling system, the exhaust manifolds are not cracked (I magnafluxed them, not pressure tested). Is there anything else I should be doing while the engine is out ?
Thanks
