    Oh the joys of changing out spark plugs under a center console, it only took me a mere 3 hours... yippie. :-)

    That is why I like my 75 center console. The whole front folds down. Spark plugs, 20 minutes. Carb, 7 minutes. Did both today, 30 minutes with a cup of coffee.

      Trust me I look at how the console could be modified to do just that.

      My hands barely fit between the gutter rails. Good thing I have long arms and reached from the front.

            I'll let one of my little elves go for a little while one evening to do it next time!

              Still trying to figure out the ignition gremlin... replaced plugs and rotor also cleaned rotor cap and she still will fire off not even a little bit. No one carries the rotor cap so I have one on order, hopefully it will show up today.

                  If it were me the first thing I would do is pull the coil wire from the distributor and see if there is fire when you turn her over. If yes, and it is strong fire, then you are probably on the right track with distributor, etc. Though unlikely, would also verify the wires are set up for the correct firing order. (Worked on a boat one July 4th where a mechanic put wires on in the reverse order.)

                  If there is no fire verify coil is good and receiving correct voltage. Will need to know if you have points and condenser or electronic ignition before offering more info.

                  PS: Good luck!

                    I ordered a cap and rotor from go2marine Wednesday and sadly it will not be here until Tuesday (not the best turn around time) found the same parts yesterday on Amazon and I'll have it on Sunday (tommrow). Spark at the coil is strong not so much at the plugs. It's like 50% less there. I'll check the firing order today, MSD ignition.

                      I'll bet its that msd box.
                      i had a msd 6al box that gave me fits!
                      jump starting the motor if its ever done can spike the voltage and take out the box.
                      not saying thats what always happens but its a possibility.

                        Well that may be what happened in sorts... I'm not sure if when my son and I tried starting the Heather Rose if he had the battery charger on boost at one point or another. I don't want to ask him because he'll feel guilty about it.

                      Pat, I have an MSD box that I am not using. PM me your address and I'll get it headed your way.

                          The quality of the 6AL is not what it used to be. I prefer the HEI module.
