We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common !
The note Paul posted on the "photo of the day" the other day about all the time and money spent on boats, only to leave the distributor cap in place until it fails, is a good one. I recommend everyone (no matter what motors you are running) buy new caps at the beginning of each season as a good proactive boating practice, and keep the good ones that come off the boat as spares. Mark them with an indellible ink as "good used", and stash them aboard where you can get them. In addition, I would wipe them down with WD40 and put them in a zip lock bag to keep them from corroding or getting damaged. Each year as more "good used" caps come aboard, you may elect to take a chance and run a little longer. However, in my long experience with boats, a little proactive work in advance is not only a safety issue, it will potentially keep you from being stranded at a very inopportune time, possibly with guests aboard too.
For the $70 or so it will take to get new caps (and rotors too), that is roughly the equivalent of 20 gal of fuel, so let's keep this in perspective.
