I am trying to replace the blue drain plugs in my motor - Mercury 330 HP Scorpion, that the dealer removed last fall. I've found 5 of the 7 drain holes but I can't seem to find the last two. I've been hanging upside down in my engine bay long enough that my neighbours are starting to wonder. Any help would be appreciated, photos would be terrific (I do have the manual). I have located the port and cylinder block and exhaust manifold plugs and one other one closer to the stern (not sure what it is called). I think the ones I can't find are (as labelled in the manual) the check valve, and the water circulating pump hose or the fuel cooler to thermostat housing hose. Help! Thanks
