This is my first boat. I have a 1989 Invader V177 w/3.0L Merc S/N OB450801 that was purchased after being in storage for 15 years. It has 35 hours total, all of which was put on in '89. I have replaced many siezed, corroded parts and am ready to start it up for the first time but there is no spark at the plugs. I replaced the cap, rotor, points (set at 0.022"), plugs, starter, alternator etc and have a fresh battery and cleaned all electrical terminals on the engine. I can get a spark to ground from the coil wire when I crank the engine but I'm not sure if it is weak or not, seems thin and yellow in the sunlight. I can also induce a spark if I push the cut-out switch momentarily off and on with the ignition on. The coil is original though and there is 12.74 volts available on the + side of it. Any suggestions on what to look for or test?
