        I have used the dull aluminum for my Johnson projects from NY marine. It looks great but it has a fleck to it and it is quite shiny. Much different than the original Merc colour.

          Perhaps his Mercury dull aluminum is a different formulation from his OMC dull aluminum. Don’t know for sure, as I don’t do Mercurys.

            Talked to Peter McDowell today same dull aluminum used on both Johnson and Mercs. Checked the compression today top cylinder is 110 lbs and bottom is 80lbs. There is no play when the pistons are in the middle of thier stroke but when they reach tdc and switch to thier downward movement there is definately some play-slop for lack of a better term. In other words the crank will move slightly before the pistons start to move. Also seems to be some resistance turning the crank with the plugs out. Do these things seem normal?the resistance almost feels like a bad crank bearing?

                Where would I even start to find rings for this old motor?

                  First,
                  check with a ohmeter from 3k to open from ground to spark plug to test the secondary windings

                      Happy New Year,

                      I sent you a private message as we have the new piston rings on-hand. We can help with many other parts for a KD4 or most any vintage Mercury (and a growing amount of Evinrude and Johnson) as well (our family marine business turned 65 years old as a corporation yesterday, and is 70 years old since it’s founding this year – all the while with boats, outboard motors, and such).

                      Thank You,
                      Joe
