So here's my problem I called merc with engine #s they gave me a merc & gm part number for exhaust push rods both were about 50 thousandths longer than the ones that are in the boat now. Can someone tell me where I might get the correct part # they are 3/8 by 8.690 they look like a stock GM performance push rod.

comp cams makes them .go with 8.700.

I have a used set of stock Gen6 pushrods that you can have, just pm me your address. I guess I better measure them first though. Stand by

Nope, mine measure 8.635" sorry. As Mike stated, just order up some aftermarket ones. They come in .050" increments. That extra .010 shouldn't hurt a thing.
