    An easy one for you guys: tools?

    Merry Christmas all!!

    I'm going to look at a 1992 115 HP V4 Johnson outboard and want to know what tools I need to take. (actually, it's attached to the boat I'm trying to buy). Are these motors SAE or metric bolts/nuts? What size sparkplug socket do I need? Are the sparkplugs recessed or easy access? What size compression tester adapter will thread in the spark plug hole? Is the lower unit drain plug a large flathead screw? Anything else? I have a ton of mechanics tools but don't want to bring the whole ton!

    Anything special I need to look out for with these motors? I want to check it out thoroughly.

    Thanks much!

    Take an adjustable crescent wrench to turn the (biggest) flat screwdriver if you are going to remove the drain plug. Take a hammer to hit it with to start the turning and maybe to get it in the slot, sometimes the slot gets buggered.
