    Is this a ground wire for hydraulic pump?

    Yeah, 44 year old boat, been in and out many times I’m guessing. Bolt only holds piece that covers flywheel. Original was probably lost at one time and fella replaced it with what he could find.

    Is this a ground wire for hydraulic pump?

    1978 Mercruiser, serial number 3773776. Motor was removed in a shop. For various reasons, I am putting back in. This is the only wire I’m not sure of.

    Merc 140 fuel pump install, no ros?

    Oops….good eye! I forgot to mention that the clear line you see going line going from the pump to the “tank” is strictly there for a test run while motor is out of boat. It will go to a small gas can. Actual fuel line is to code. Great catch.
